What a mortgage lender examines before saying yes

A lender approves your mortgage process by checking five concrete things: your credit score, your income and employment history, the size of your down payment, your debt-to-income ratio, and the property itself. They are not making a judgment about you as a person. They are calculating the statistical likelihood that you will repay the loan, and they price or deny the loan based on that calculation.

The process takes 30 to 45 days from process to closing. During that time, a loan officer will order a credit report, verify your employment by contacting your employer directly, order an appraisal of the property, and pull title records. You will be asked to provide tax returns, pay stubs, bank statements, and a written explanation for anything unusual in your financial history. The lender is not being difficult — they are following rules set by the agencies that buy mortgages from them after closing.

Key Takeaways

  • Lenders look at your credit score, income, down payment size, existing debts, and the property value — not your character or life story.
  • You will need to provide recent tax returns, pay stubs, bank statements, and employment verification; the lender contacts your employer directly.
  • Your debt-to-income ratio — the percentage of your gross monthly income that goes to all debt payments — cannot usually exceed 43 percent.
  • The property itself is appraised independently; if it appraises below the purchase price, you may need to pay the difference out of pocket or renegotiate.
  • Pre-approval is not a may provide; final approval depends on the appraisal, employment verification, and no major changes to your finances between process and closing.

Credit score and credit history

Most lenders require a credit score of at least 620 to consider you, though scores of 740 and above get the best interest rates. Your credit score is a three-digit number generated by Equifax, Experian, or TransUnion based on your payment history, the amount of debt you carry, the length of your credit history, and the mix of credit types you use.

The lender will pull your full credit report, not just the score. They are looking for late payments, collections accounts, foreclosures, or bankruptcies. A single late payment from five years ago is less damaging than a recent one. A bankruptcy that was discharged seven years ago is less damaging than one from last year. If you have had credit problems, the lender wants to see evidence that you have since paid on time consistently.

You can request a free credit report from each of the three bureaus once per year at annualcreditreport.com. Check it for errors before you explore for a mortgage. If you find a mistake — a payment marked late that you made on time, an account that is not yours — you can dispute it directly with the bureau. Disputes typically take 30 days to resolve.

Income, employment, and tax returns

The lender will verify your employment by calling your employer directly. They will ask how long you have worked there, whether you are full-time or part-time, and whether there are any plans to terminate your employment. If you have been at your current job for less than two years, they will ask for employment history going back two years and may require a letter from your previous employer.

You will need to provide your last two years of tax returns. If you are self-employed, own a business, or receive income from investments or rental property, the lender will examine these returns closely to calculate your average income. They typically average the last two years rather than using the most recent year alone, because income can fluctuate. If your income dropped significantly in the most recent year, the lender may use the lower figure.

You will also need recent pay stubs — usually the last 30 days — to show that you are still employed and earning what you reported on your process. If you receive bonuses, commissions, or overtime, bring documentation showing that this income is recurring and likely to continue. A lender will not count a one-time bonus as part of your regular income.

Down payment and savings

The size of your down payment affects both whether you are approved and what interest rate you receive. A larger down payment means you are borrowing less and the lender is taking on less risk. Conventional loans typically require a down payment of 5 to 20 percent of the purchase price. Federal Housing Administration (FHA) loans allow down payments as low as 3.5 percent. Veterans Affairs (VA) loans may require no down payment at all if you are a may have access to veteran.

The lender will ask where your down payment money came from. If you received a gift from a family member, you will need a signed letter from that person stating that the money is a gift and does not need to be repaid. If you withdrew money from savings or investments, you will need bank statements showing the withdrawal. The lender wants to confirm that you did not borrow the down payment money, because that would increase your debt and change your debt-to-income ratio.

You will also need to show that you have cash reserves after closing — usually two to six months of mortgage payments in a savings account. This demonstrates that you can weather a job loss or unexpected expense without defaulting on the loan. Some lenders require more reserves if you are putting down less than 20 percent.

Debt-to-income ratio and existing obligations

Your debt-to-income ratio is the total of all your monthly debt payments divided by your gross monthly income. Most lenders will not approve a mortgage if your ratio exceeds 43 percent. Some will go as high as 50 percent if your credit score is very high and your down payment is large, but 43 percent is the standard threshold.

The lender counts all debt: car loans, student loans, credit card balances, child support, alimony, and any other monthly obligation. They do not count utilities, insurance, or rent. They do count the new mortgage payment you are about to take on. If your gross monthly income is $5,000 and you already owe $1,500 per month in car and student loans, you can afford a mortgage payment of no more than $650 per month (43 percent of $5,000 is $2,150; subtract the $1,500 you already owe).

If your debt-to-income ratio is too high, you have two options: pay down existing debt before explore, or wait until your income increases. Paying off a car loan or credit card before explore can lower your ratio enough to cross the approval threshold. Asking for a raise or changing jobs to higher-paying work will increase your income and lower your ratio.

Property appraisal and title search

The lender will order an independent appraisal of the property you are buying. The appraiser is not employed by the lender; they work for a third-party appraisal company. The appraiser inspects the property, measures it, checks for structural problems, and compares it to similar properties that have sold recently in the same area. The appraisal report includes the appraiser's opinion of the property's fair market value.

If the appraisal comes in lower than the purchase price, you have three options: pay the difference out of pocket, renegotiate the purchase price with the seller, or walk away from the deal. The lender will not lend more than the appraised value, because they are using the property as collateral. If you default, they will foreclose and sell the property; they need to know it is worth at least what they are lending.

The lender will also order a title search. A title company will examine the public records to confirm that the seller owns the property free and clear, or that any existing liens will be paid off at closing. If there are unpaid property taxes, contractor liens, or other claims against the property, these must be resolved before the lender will fund the loan.

Pre-approval versus final approval

Pre-approval is a preliminary decision based on the information you provide. The lender reviews your credit, income, and debts and tells you how much they are willing to lend. Pre-approval is useful because it shows sellers that you are a serious buyer and have already passed a basic financial check. It is not a may provide of a loan.

Final approval comes after the appraisal, employment verification, and title search are complete. Between pre-approval and final approval, the lender will re-check your credit to make sure you have not opened new credit accounts or missed any payments. They will also confirm that you are still employed. If you change jobs, take on new debt, or miss a payment, your final approval can be withdrawn.

Some lenders issue a "clear to close" letter once final approval is granted. This means the loan is ready to fund and you can schedule your closing appointment. Do not make any large purchases or changes to your finances between clear to close and closing day; lenders sometimes do a final check the day before closing.

Common reasons lenders deny mortgages

The most common reason for denial is a debt-to-income ratio that is too high. The second most common is a credit score that is too low or a recent late payment. The third is an appraisal that comes in below the purchase price and the buyer cannot or will not make up the difference.

Other reasons include unstable employment history, insufficient income documentation, a large unexplained deposit in your bank account, or a major change in your finances between pre-approval and final approval. If you are denied, ask the lender for a specific reason in writing. Some reasons can be fixed — paying down debt, waiting for a late payment to age, or finding a less expensive property. Others, like a recent bankruptcy, require time to pass.

Frequently Asked Questions

What is the minimum credit score I need to get a mortgage?

Most conventional lenders require a credit score of at least 620. FHA loans may go as low as 580 with a larger down payment. Scores above 740 typically receive the best interest rates. Your full credit history matters too — a recent late payment is more damaging than one from several years ago.

Can I get a mortgage if I am self-employed?

Yes, but the process takes longer. Lenders typically average your income over the last two years using your tax returns. You may need to provide profit-and-loss statements, business tax returns, and bank statements showing business deposits. If your income has been declining, the lender will use the lower figure.

What happens if the appraisal is lower than the purchase price?

The lender will not lend more than the appraised value. You can pay the difference out of pocket, ask the seller to lower the price, or withdraw from the purchase. Some sellers will renegotiate if the appraisal is significantly lower than expected.

Can I get a mortgage with a recent bankruptcy?

Most lenders require at least two years to pass after a bankruptcy is discharged before they will consider you. Some will wait three to seven years depending on the type of bankruptcy and your credit activity since then. Rebuilding your credit with on-time payments during this period will improve your chances.

What if I change jobs between pre-approval and closing?

Tell your lender when ready. If you are moving to a similar job with similar pay, the lender may straightforward verify employment with your new employer. If you are taking a pay cut or moving to a less stable field, your approval could be withdrawn. Avoid changing jobs during the mortgage process if possible.
