You already know your credit score matters for a mortgage. What most buyers don’t know is exactly how much it matters — or whether the number on their phone’s credit monitoring app is even the right number their broker will use at underwriting. That gap between “I know it matters” and “I know exactly what it means for my situation” is where a lot of buyers get stuck, sometimes for months longer than necessary.
Here’s the honest answer: there is no single universal minimum credit score to buy a house. The floor depends on which loan program you’re applying for, which investor your broker submits to, and what overlay that investor applies on top of the program guidelines. A score that qualifies you for one loan type may disqualify you from another — and a score that one bank declines may be perfectly acceptable through a broker who shops multiple investors simultaneously.
What this article covers, in plain terms: the actual minimum credit scores by loan program (with real sources), how your score tier translates into rate differences and real dollar costs over 30 years, how PMI compounds the problem when your score is lower and your down payment is smaller, why a broker gives you more options than a single bank, and what the fastest legitimate levers are for improving your score before you apply. I’ll also walk through a full Total Cost of Ownership worksheet so you can see the real financial stakes — not just a monthly payment number.
The goal is to leave you with a precise picture of where you stand and exactly what to do next.

The Real Program Floors — Minimum Scores by Loan Type
Let’s start with the official program minimums, because these are often misquoted. These are the floors set by the agencies and the government — not the floors set by any individual broker or bank, which may be higher.
FHA Loans: According to the HUD FHA Single Family Housing Policy Handbook 4000.1, FHA allows a minimum 500 FICO score with a 10% down payment, and a minimum 580 FICO score with the standard 3.5% down payment. In practice, many investors apply overlays that push the effective floor to 580 or even 620 — so the program technically allows 500, but your broker’s investors may not.
Conventional Loans (Fannie Mae / Freddie Mac): The Fannie Mae Selling Guide and Freddie Mac Single-Family Seller/Servicer Guide set the conventional minimum at 620 FICO for most loan products. This is a hard floor for GSE-backed loans.
VA Loans: The VA itself does not set a minimum credit score — that’s a meaningful distinction. The VA guarantees the loan; the investor sets the overlay. Most investors require 580–620. Through Coast2Coast Mortgage, we can access VA investors down to 500 FICO, which opens the door for veterans who’ve had credit challenges and may otherwise be told they don’t qualify.
USDA Loans: The USDA Rural Development guidelines typically require a 640 FICO for approval through the automated underwriting system (GUS). Manual underwriting may allow exceptions, but 640 is the practical benchmark most brokers work from. Buyers interested in rural financing should also review USDA mortgage eligibility requirements to confirm their property and income qualify before applying.
Non-QM and Portfolio Products: Some non-QM products allow scores as low as 500 FICO, depending on the product, the LTV, and the compensating factors. These carry higher rates and stricter terms, but they exist — and they matter for buyers who don’t fit the conventional or government-backed mold.
Now, the critical distinction that trips up many buyers: the difference between a program minimum and an investor overlay. Fannie Mae says 620. But the investor behind a specific broker’s conventional product might require 640 or 660. A broker who accesses multiple investors can shop your file to find the investor whose overlay aligns with your actual score — something a single bank with one set of guidelines simply cannot do.
One more score model distinction worth understanding before we go further: the soft-pull pre-qualification process at Better Mortgage Rates uses VantageScore 4.0, which is what powers the NoTouch Credit check. At underwriting, GSEs and most investors use a tri-merge FICO pull — specifically Equifax FICO 5, TransUnion FICO 4, and Experian FICO 2, with the middle score used as the qualifying score. These two numbers can differ, sometimes meaningfully. Knowing both is important so there are no surprises when you move from pre-qualification to full underwriting. For a deeper look at how these score models affect Virginia buyers specifically, see our guide on credit score requirements for mortgage in 2026.
How Your Score Tier Shapes Your Rate and Total Cost of Ownership
Qualifying is only part of the story. The more consequential question is what your score costs you in rate — and what that rate difference costs you over 30 years.
For conventional loans, Fannie Mae and Freddie Mac publish Loan-Level Price Adjustments (LLPAs) — essentially pricing penalties applied in tiers based on credit score and LTV. You can review the current LLPA matrix at fanniemae.com/funding-and-liquidity/mortgage-backed-security/llpa-matrix. The key takeaway: 760 and above is the best-pricing tier. Every band below that — 740–759, 720–739, 700–719, 680–699, 660–679, 640–659, 620–639 — carries an additive cost that translates directly into a higher rate or additional points at closing.
To show what this means in real dollars, here is a full Total Cost of Ownership worksheet using a concrete example. All rate differentials are illustrative of typical LLPA impact and are not guaranteed current rates.
Base Scenario: $350,000 purchase price, 20% down ($70,000), $280,000 loan, 30-year fixed, Henrico County, VA.
Henrico County’s property tax rate is $0.85 per $100 of assessed value. On a $350,000 assessed value: $350,000 ÷ 100 × $0.85 = $2,975 per year, or approximately $247.92 per month.
Homeowners insurance estimate: approximately $125–$150 per month for a home in this price range (varies by coverage and location).
PMI: Not applicable at 20% down — this is the advantage of reaching that threshold.
760+ Score Borrower (Best LLPA Tier):
At a hypothetical rate of X%, the monthly principal and interest payment on $280,000 over 30 years, plus $247.92 in property tax and $137 in insurance, represents the full housing payment. The total interest paid over 30 years at the best-tier rate reflects the full cost of borrowing at the most favorable pricing available.
680 Score Borrower (Meaningful LLPA Impact):
A 680 score borrower on the same $280,000 loan faces an LLPA-driven rate premium that typically translates to 0.50–0.75% higher in rate compared to the 760+ tier, depending on LTV and current market conditions. On a $280,000 loan, a 0.625% rate difference translates to roughly $100–$115 more per month in principal and interest. Over 30 years, that difference compounds to approximately $36,000–$41,000 in additional total interest paid — on the same house, the same loan amount, the same neighborhood. The only variable is the credit score tier.
This is the number that reframes the entire conversation. Improving your credit score before applying is not a bureaucratic hurdle — it is a direct, quantifiable financial return. Spending 60–90 days raising your score from 680 to 760 can be worth tens of thousands of dollars in interest savings over the life of the loan. Understanding exactly how your credit score impacts your mortgage rate is the first step toward making that calculation for your own situation.
For buyers in other Virginia localities: Chesterfield County and Richmond City each publish their current tax rates on their official assessor pages — always verify your specific county’s current rate before building your own TCO worksheet.
When Lower Score Meets Lower Down Payment — The PMI Compounding Effect
Here’s where the numbers get genuinely uncomfortable for buyers who are working with both a lower credit score and less than 20% down. These two factors don’t just add costs — they multiply them.
Consider a second scenario: same $350,000 purchase price, but now with 5% down ($17,500), resulting in a $332,500 loan at 95% LTV. At this LTV, PMI is required — and PMI is not a flat cost. It is priced by credit score tier and LTV, just like your rate. A borrower with a 760+ score at 95% LTV pays meaningfully less in monthly PMI than a 680-score borrower at the same LTV. The exact premium varies by PMI insurer, but the directional reality is consistent: lower score equals higher PMI cost, stacked on top of the already higher rate from LLPAs. Buyers who want to understand all their options for eliminating this cost should review strategies on how to avoid PMI on a mortgage before committing to a loan structure.
So the 680-score borrower with 5% down is paying: a higher rate (from LLPAs), plus higher PMI (from score-tiered PMI pricing), plus the base cost of borrowing more (since they put less down). All three costs are running simultaneously.
Now for the PMI removal math, because this is where many buyers have questions. PMI removal is governed by the Homeowners Protection Act (HPA) of 1998, as explained by the CFPB. On a $280,000 loan, the 80% LTV threshold — the point at which you can request PMI cancellation — is a loan balance of $224,000. That means you need to pay down $56,000 from the original balance.
On a standard 30-year amortization schedule, reaching a $224,000 balance from $280,000 takes approximately 8–10 years, depending on the interest rate. The lender is required to automatically cancel PMI when the loan reaches 78% LTV based on the original amortization schedule — that’s a balance of approximately $218,400 on a $280,000 loan. You don’t have to wait that long, though: you can request cancellation at 80% LTV, and you can also request removal based on appreciation by ordering a new appraisal that demonstrates your current LTV has reached 80% or below.
The strategic implication is straightforward: for a buyer with a 660–680 score who is planning to put 5% down, there is a real case to be made for taking 60–90 days to improve the score first. The combination of a better rate tier and lower PMI costs — sustained over 8–10 years until PMI drops — can represent a substantially better financial outcome than locking in the compounded cost of both penalties today. Buyers weighing this decision may also find it useful to explore low down payment mortgage strategies that balance score improvement against time-to-purchase.
Broker vs. Bank — Why the Same Score Gets Different Results
One of the most important things buyers don’t know is that the same credit score can produce completely different outcomes depending on where they apply. This isn’t about negotiating — it’s about structural access to investors.
A single bank or direct retail lender has one set of overlays and one investor. If your file doesn’t fit their box, the answer is no. A mortgage broker submits your file to multiple investors simultaneously — meaning a 600 FICO that gets declined at one investor’s overlay may be perfectly approvable at a different investor the broker has access to, sometimes at a meaningfully better rate. This is the core structural advantage of the broker model for buyers with non-standard credit profiles. For a detailed breakdown of how to evaluate your options, our guide on choosing the right mortgage lender walks through exactly what to look for.
Here is a factual comparison of channel types relevant to this decision:
Channel Comparison: Broker vs. Retail Direct
Better Mortgage Rates / Coast2Coast Mortgage (Broker Model): Shops hundreds of investors simultaneously on a single file. Overlay flexibility varies by investor — can access VA investors down to 500 FICO and non-QM products for lower score profiles. Soft-pull pre-qualification available via NoTouch Credit (VantageScore 4.0, no hard inquiry). Rate shopping across investors on a single credit pull. Uses tri-merge FICO at underwriting per GSE requirements.
Rocket (Retail Direct): Single investor / proprietary channel. Overlays set internally. Soft-pull pre-qualification tools available on their platform. Rate reflects their internal pricing, not a shopped market. Strong technology platform for streamlined applications.
CrossCountry Mortgage (Retail / Correspondent): Correspondent lender with access to multiple product lines. Overlays set at the company level. Not a broker model — does not shop your file to outside investors in the same way.
Veterans United (VA-Focused Retail): Specializes in VA loans. Strong VA expertise and service model. Retail direct channel — single investor overlay set. Well-suited for VA borrowers with strong profiles.
Movement Mortgage (Retail): Retail direct lender with proprietary underwriting. Known for fast processing. Single investor overlay set.
The soft-pull advantage deserves specific emphasis for rate-shopping buyers. When you apply at multiple retail lenders, each one pulls your credit — and multiple hard inquiries in a short window, while often grouped by FICO scoring models, can still cause anxiety and confusion. Through a broker using a soft credit pull for pre-qualification, you see your real options, real rate scenarios, and real loan programs without any impact to your credit score. That’s the no hard inquiry mortgage pre-approval process Better Mortgage Rates uses through NoTouch Credit — and it’s particularly valuable for buyers who are still assessing their options or who are sensitive about additional inquiries. You can learn more about how this works in our full guide on soft credit pull mortgage shopping.
The Fastest Levers for Raising Your Score Before You Apply
If your score isn’t where you want it to be, the good news is that certain actions move the needle faster than others. Here are the highest-impact, fastest-moving tactics for mortgage applicants specifically.
Pay Down Revolving Utilization: This is typically the single fastest lever available to most borrowers. Credit utilization — the ratio of your current balance to your credit limit on revolving accounts — has an immediate impact when it changes. Getting utilization below 30% helps; getting it below 10% can produce a meaningful score jump, sometimes within one reporting cycle. If you have a card sitting at 80% utilization, paying it down before your application is one of the highest-ROI moves you can make.
Dispute Errors on Your Tri-Merge Report: Errors on credit reports are more common than most people expect. Before applying, pull all three bureau reports and review them carefully. A collection account that isn’t yours, an account showing late when it wasn’t, or a balance reported higher than the actual balance — all of these can be disputed and corrected, sometimes producing a meaningful score improvement.
Avoid New Credit Applications: Every hard inquiry from a new credit application can cause a small, temporary score dip. In the 90 days before applying for a mortgage, avoid opening new credit cards, financing a car, or applying for any other credit product. The inquiry impact is modest, but when you’re trying to cross a score tier threshold, modest matters.
Don’t Close Old Accounts: Closing an old credit card reduces your available credit limit and can shorten your average age of accounts — both of which can hurt your score. Leave old accounts open, even if you don’t use them regularly.
Rapid Rescore — A Broker-Level Tool: This is one that many buyers don’t know exists. If you pay down a card or resolve a dispute, you normally have to wait for the next monthly reporting cycle for the update to appear on your credit file. A broker can initiate a rapid rescore — a process that updates your credit file with the corrected or improved information in 3–5 business days rather than weeks. This is not score manipulation; it simply accelerates the reporting of accurate, already-resolved information. It is a broker-level tool not available to consumers directly, and it can be the difference between qualifying this month versus next month.
If you need more structured help with credit improvement, the credit restoration resource on this site can point you in the right direction. And the right first step in any case is a soft-pull pre-qualification — a mortgage pre-approval that won’t hurt your credit score — that shows you exactly where you stand today, which programs you qualify for, and precisely how much score improvement would change your options. No credit impact, real information.

8 Questions Buyers Always Ask About Credit Scores and Mortgages
1. What is the minimum credit score to buy a house?
It depends on the loan type. FHA allows as low as 500 with 10% down; conventional loans require a minimum 620 for Fannie Mae and Freddie Mac products; VA loans have no official GSE minimum but most investors require 580–620; USDA typically requires 640. Individual broker overlays may set higher floors, and non-QM products can go lower than government-backed minimums in some cases.
2. Does checking my credit score hurt my mortgage application?
A soft credit pull — like the one used in a soft pull mortgage pre-qualification — does not affect your credit score at all. A hard inquiry, which occurs when a lender formally pulls your credit for underwriting, can cause a small, temporary dip. FICO’s scoring models typically group multiple mortgage-related hard inquiries within a 45-day window as a single inquiry, minimizing the impact of rate shopping through multiple lenders.
3. Which credit score do mortgage brokers use — FICO or VantageScore?
At underwriting, GSEs and most investors require a tri-merge FICO pull — Equifax FICO 5, TransUnion FICO 4, and Experian FICO 2 — with the middle score used as the qualifying score. For soft-pull pre-qualification, Better Mortgage Rates uses VantageScore 4.0 through the NoTouch Credit process. These two scores can differ, so understanding both is important before you move to full underwriting.
4. Can I get a mortgage with a 580 credit score?
Yes, in many cases. FHA loans allow 580 with 3.5% down, and some VA investors accept 580 as well. The rate and terms will reflect the score tier, but 580 is not a disqualifying number for all programs. A broker who shops multiple investors has a better chance of finding an approvable path for a 580-score borrower than a single bank with one overlay.
5. How much does my credit score affect my mortgage rate?
Meaningfully. For conventional loans, Loan-Level Price Adjustments (LLPAs) create a pricing tier structure where a 680-score borrower typically pays 0.50–0.75% more in rate than a 760+ borrower at the same LTV. On a $280,000 loan over 30 years, that difference can represent $36,000–$41,000 in additional total interest paid. The exact impact varies with current market conditions and the specific LLPA matrix in effect.
6. How long does it take to improve a credit score for a mortgage?
It depends on what’s dragging the score down. Paying down revolving utilization can show results within one reporting cycle (30–45 days). Disputing errors can take 30–60 days through the standard process, or as little as 3–5 business days through a broker-initiated rapid rescore once the underlying issue is resolved. Building score through positive payment history takes longer — typically 6–12 months for meaningful improvement from that factor alone.
7. Can a co-borrower’s higher credit score help my application?
It depends on the loan program. For conventional loans, the qualifying score is typically the lower middle score among all borrowers — so a co-borrower with a higher score doesn’t automatically raise the qualifying score. However, a co-borrower can add income to help with debt-to-income ratios, which is a different and often equally important qualification factor. Discuss the specific structure with your broker before adding a co-borrower.
8. What is a soft credit pull and why does it matter for mortgage shopping?
A soft credit pull is a credit inquiry that does not appear on your credit report as a hard inquiry and does not affect your credit score. For mortgage shoppers, this matters because it allows you to get a real mortgage pre-approval without a hard pull — you can see your actual loan options, rate scenarios, and program eligibility without any score impact. The no hard inquiry mortgage pre-approval process at Better Mortgage Rates uses VantageScore 4.0 through NoTouch Credit, giving you real information before you commit to a full application.
Putting It All Together — Your Next Step Starts Without a Credit Hit
Here’s what this article has covered, distilled to the essentials. Minimum credit scores vary by loan program — from 500 on FHA with 10% down to 620 for conventional, with VA and USDA sitting in between. Your score tier doesn’t just determine eligibility; it determines your rate through LLPA pricing tiers, and that rate difference translates directly into tens of thousands of dollars in additional interest over a 30-year loan. When a lower score is combined with less than 20% down, the compounding effect of both a higher rate and higher PMI costs makes the financial case for score improvement even stronger. And a mortgage broker, by shopping your file across multiple investors, gives you meaningfully more options than any single bank can offer.
The right first step for most buyers is a soft-pull pre-qualification — one that shows you real numbers, real programs, and real rate scenarios based on where your score actually stands today, without any impact to your credit. That’s exactly what Better Mortgage Rates offers through the NoTouch Credit process: a no credit hit mortgage application start that gives you the information you need to make a smart, confident decision about timing, loan type, and whether a short period of score improvement is worth it before you lock.
