This guide walks you through the mortgage pre approval process from first look to signed letter. By the end you will hold a pre-approval backed by verified documents, and you will know the real monthly cost of the home it supports, not just principal and interest. Before you start, gather recent pay stubs, two years of tax returns and W-2s, two months of bank statements, and a government-issued ID. Having these on hand turns a week of back and forth into a day or two.

Step 1: Understand What Pre-Approval Is and Pick Your Target Price Range
Two terms get mixed up constantly. Pre-qualification is an estimate built from information you report yourself: income, debts, savings. Pre-approval goes further: your documents and credit are reviewed, and you receive a written, conditional letter stating a loan amount. Neither is a final loan commitment. The letter can still change if your finances shift, the appraisal comes in low, or underwriting finds something new. It also does not lock a rate.
The most common mistake is treating the maximum on that letter as your budget. A maximum reflects what a loan program will allow, not what fits your life alongside childcare, travel, retirement savings, and a repair fund. Set a monthly housing payment you are comfortable with first, then work backward to a price.
Duane Buziak explains that the payment printed on a pre-approval is never the whole cost. The full picture is Total Cost of Ownership, which includes:
- Principal and interest
- Property tax, which varies by county
- Homeowners insurance
- Private mortgage insurance (PMI), if your down payment is under 20% on a conventional loan
- HOA dues, if the property has them
Write down a target monthly number now, and a price range that roughly matches it. You will test that range against real figures in Step 7.
Step 2: Check Your Credit Profile Without Hurting Your Score
Start at AnnualCreditReport.com, the federally authorized source for free reports from the three bureaus. Read each one for accounts you do not recognize, wrong balances, and late payments that were actually on time. Dispute errors with the bureau in writing before you apply, since corrections can take weeks.
Expect your score to look different from the number in a consumer app. Mortgage underwriting has historically relied on specific FICO versions, and the requirements are set by Fannie Mae and Freddie Mac guidance, which changes. Check their current published requirements rather than assuming your app matches. Vantage Score 4.0 is another scoring model; in plain terms, it is an alternative way of reading the same credit file, and how much weight it carries depends on the program and the investor, so confirm that for your own file.
For a first look, a soft credit pull mortgage option avoids damage entirely. Duane Buziak uses NoTouch Credit Pull, so your initial review causes no credit hit. You see where you stand before any hard inquiry is recorded.
Scoring models generally treat several mortgage inquiries made within a short shopping window as one. The length of that window depends on the model, so verify the current rule with the CFPB as of 2026. Starting soft sidesteps the question.
Until closing, avoid anything that moves your file:
- Opening new credit cards or store accounts
- Financing a car or furniture
- Closing old accounts, which can shorten your history and raise utilization
- Co-signing for anyone
Step 3: Calculate Your Debt-to-Income Ratio and Down Payment Position
Debt-to-income (DTI) is the share of gross monthly income that goes to debt. The formula: add your monthly debt payments and your proposed housing payment, then divide by gross monthly income.
Here is an illustration with made-up numbers. Suppose gross income is $9,500 a month. Debts are a $350 car payment, $250 student loan, and $100 minimum card payment, totaling $700. The proposed housing payment is $3,075 (built in Step 7).
- Front-end DTI (housing only): $3,075 / $9,500 = about 32.4%
- Back-end DTI (housing plus all debts): $3,775 / $9,500 = about 39.7%
Limits vary by program, and they shift with the borrower’s credit, reserves, and automated underwriting findings. Conventional loans follow the Fannie Mae Selling Guide, FHA loans follow HUD guidance, and VA loans follow VA.gov requirements. Check each for current ceilings as of 2026 instead of relying on rules of thumb.
Next, decide your down payment. On a conventional loan, putting down less than 20% generally means PMI, which adds to the monthly cost until you reach the removal thresholds covered in Step 7. Also plan for cash reserves, since some programs and files require several months of payments left in the bank after closing. If part of your down payment is a gift, expect a signed gift letter and a paper trail showing the funds moving from the donor to you. Gift rules differ by program, so confirm them before the money moves.
Step 4: Gather and Organize Your Documents
What you submit depends on how you earn income.
- W-2 employees: about 30 days of recent pay stubs and two years of W-2s
- Self-employed: two years of complete personal (and business, where applicable) tax returns, plus a year-to-date profit and loss statement
- Retirement, Social Security, or other income: award letters, plus proof the income continues
- Everyone: a government ID and two months of statements for every account you are using for funds
Bank statements must include all pages, even the ones that look blank, because underwriters verify that nothing is missing. Any large deposit that is not regular payroll needs an explanation and a paper trail: a sale receipt, a transfer from your own savings, or a gift letter. Undocumented cash deposits are one of the most common reasons files stall.
Avoid sending partial statements or unsigned returns. An incomplete document is usually rejected outright, and the review clock effectively restarts when the corrected version arrives.
Save each file as a clearly named PDF, for example 2025-Tax-Return-Signed.pdf or Checking-Statement-September-2026.pdf. Phone photos with cropped corners are a frequent culprit. Duane Buziak’s process runs 24/7, so you can upload whenever it suits you, including evenings and weekends.
Step 5: Compare Brokers and Lenders Before You Submit a Full Application
A bank or single-source mortgage company prices loans from its own menu. A broker, such as Duane Buziak, can shop hundreds of lenders at one time and place your file where the pricing and guidelines fit best. That is often most useful when your situation has a wrinkle: self-employment income, a lower score, or a cash-out refinance up to 90%.
The comparison below is general and based on how these companies publicly describe themselves. Details change, so verify each row as of 2026 before relying on it.
- Duane Buziak at Better Mortgage Rates (broker): rates come from many wholesale sources compared at once; initial review uses a no-touch soft pull; offers a range of loan types; 24/7 process; works with Realtor referrals.
- Rocket: a large online mortgage company; pricing comes from its own loan offerings; ask what credit pull it uses at each stage; digital-first process.
- Movement: a retail mortgage company working through its own loan officers; pricing comes from its own offerings; ask about credit pull type and timing.
- Veterans United: known for its focus on VA loans; pricing comes from its own offerings; a natural comparison point if you are using VA benefits.
- A typical bank: one set of in-house programs; often a hard pull at application; process and speed depend on the branch and its underwriting queue.
Ask every company the same four questions so you can compare fairly:
- What type of credit pull do you use, and is mortgage pre approval without hard pull available at the first step?
- How long is the letter valid?
- Can you give me a fee estimate in writing?
- Has an underwriter reviewed my documents, or is the letter based on a system check alone?
The last question separates a strong letter from a weak one. A letter that is underwriter-reviewed carries more weight with sellers than one issued from stated numbers.
Step 6: Submit Your Application and Review the Loan Estimate and Pre-Approval Letter
After you submit, underwriting reviews your credit, income, assets, and documents. You will receive a conditions list, which names what is still needed, such as an updated pay stub or a letter explaining a deposit. Clear these promptly. Once the review is satisfied, you receive the conditional letter. A validity period of 60 to 90 days is common, but confirm the exact date with whoever issues yours.
When you apply for a specific loan, you will receive a Loan Estimate. The CFPB’s Loan Estimate guide explains the form section by section. Read it line by line and focus on:
- The interest rate and whether it is locked
- The APR, which folds certain costs into a rate-like figure so you can compare offers
- Estimated cash to close, which combines your down payment and closing costs
- Escrow items, meaning the property tax and insurance amounts collected monthly
Closing costs exist on every loan. Rather than chasing a promise of none, ask about no-out-of-pocket closing options, which structure how those costs are paid.
Request a letter that states the loan type, the loan amount, and the conditions attached. Specifics make it credible. A strong letter helps with Realtor referrals and gives sellers more confidence in your offer.
Finally, do not confuse the letter with a rate lock. A pre-approval does not guarantee a rate. Locking is a separate step, usually taken once you have a contract on a home, and it holds your rate for a set period.
Step 7: Build Your Total Cost of Ownership Worksheet and Plan PMI Removal
These inputs are illustrative, not a quote or an offer: a $400,000 home, 5% down ($20,000), a $380,000 loan, an assumed 6.5% fixed rate, and a 30-year term. Your actual rate will depend on your file and the market.
For property tax, the example uses Henrico County, Virginia. The county publishes its rate on its real estate assessments page. This example assumes $0.85 per $100 of assessed value as an illustration; confirm the current rate and as-of date on that page before you budget, since rates are set annually.
- Principal and interest: about $2,402
- Property tax: $400,000 x 0.0085 = $3,400 a year, or about $283
- Homeowners insurance (assumed $1,800 a year): $150
- PMI (assumed 0.6% of the loan a year, or $2,280): $190
- HOA (assumed): $50
- Total monthly cost: about $3,075
Compare that total with your Step 1 number. If your comfortable payment is $2,800, this home is too much regardless of what the letter says you can borrow. Adjust the price and re-run the math.
PMI removal math
Under the Homeowners Protection Act, as explained by the CFPB, you can generally request removal when the balance reaches 80% of the original value, and PMI ends automatically at 78%, provided you are current on payments. Verify the conditions for your loan.
- 80% of $400,000 = $320,000, meaning $60,000 of principal paid down. On a standard schedule that takes about 123 months, a little over 10 years.
- 78% of $400,000 = $312,000, reached after about 135 months, roughly 11 years.
At $190 a month, the PMI paid before the 80% point is roughly $23,000 if the premium stays flat. Extra principal payments or a documented rise in value can shorten that timeline.
Where to Go After the Letter Is in Your Hands
Before you tour a single home, check your letter’s expiration date and read every condition on it. Then keep your finances steady until closing: no new debt, no job changes without telling your broker first, and no unexplained transfers between accounts. Keep your TCO number visible while you shop, and let it, not the maximum on the letter, decide which listings you visit.
