Save for a down payment, aiming for at least 20% to avoid private mortgage insurance (PMI). Gather financial documents like tax returns, pay stubs, and bank statements. Calculate your debt-to-income (DTI) ratio and aim to keep it below 43% (see section “Debt-to-Income Ratio (DTI)”). Shop around for mortgage rates and get pre-approved to strengthen your bargaining position.
Review your credit score from all major bureaus (see section “Credit Scores and Underwriting Optimization”). Ensure you obtain your FICO score (see section “The FICO Scoring Model”) (not some other scoring model like Vantage), as this is the model most banks use for mortgage evaluations. Aim for a score of 750 or higher, which generally places you in the top credit tier. Report any errors to improve it.
Start by using a pre-qualification calculator available on various websites. These tools, based on self-reported data, can give you an initial idea of whether you qualify for a mortgage. For example, you can use NerdWallet’s pre-qualification calculator.
When entering your income, consider the following:
To make your offer stand out, consider obtaining a mortgage pre-approval from a lender. Unlike pre-qualification, which relies solely on the information you provide, pre-approval involves a credit check and more detailed questions. However, lenders typically do not review documents like W-2s or bank statements at this stage. Consequently, some sellers may not view pre-approval as significantly more reliable than pre-qualification.
For more detailed information, refer to the Consumer Financial Protection Bureau (CFPB) guidelines on mortgage pre-approval.
Upfront underwriting involves submitting your mortgage application and financial documents for review before you find a property. This pre-approval process allows lenders to assess your creditworthiness and issue a conditional commitment, speeding up the final approval once you make an offer. It reduces uncertainty, strengthens your bargaining position, and can lead to quicker closings. While many large lenders provide this service, they often keep it under wraps because it’s an upfront cost for them without guaranteed return.
Note: Use a dedicated spam email address and a throw-away phone number for this process.
You do not owe anything to the lender who provided your pre-approval. It is in your best interest to shop around, as even a 1/8 of a point difference in interest rates can save you hundreds or thousands of dollars annually.
Note: At this stage, you do NOT need to provide your full Social Security Number (SSN). Simply state, “My FICO score is X”. If they insist on a hard credit pull to give you an accurate rate, hang up. While a cluster of hard pulls technically doesn’t harm your score, it is unnecessary and a red flag if they mislead you from the start.
When comparing rates, ensure you are comparing equivalent offers. Ask each lender for their “0 points, 0 fee” rate. You can consider “buying down” your rate later (paying upfront for a lower interest rate), but during the comparison phase, stick to 0 points.
Once you find a mortgage rate you are satisfied with (after checking with at least 2–3 lenders), you can provide your Social Security number (usually through an online portal), submit basic information, and request a “rate lock”. Until you receive a form that looks like this “Loan Estimate” with “rate lock - YES” checked in the upper-right corner, the lender can change their rates for any reason.
While you are still under no obligation with this lender, most people do not switch lenders at this point. You are now ready to proceed to the formal application and closing process.
When you’re ready to apply for a mortgage, most lenders will have you do so through an online portal, though some may still accept applications via email. Typically, you’ll need to provide the following documents:
After a few rounds of review (e.g., “please send us one more month of X”, “please resend this document”, etc.), you’ll be directed to an e-signing portal where you’ll sign the formal application (similar to “Uniform Residential Loan Application”, but pre-filled), various disclosures, and other necessary documents. The goal of this process is to reach the conditional approval stage, which means the primary remaining steps are the appraisal, title work, and closing.
