What lenders examine before they say yes

A mortgage lender does not decide based on a single number. They examine your credit history (how you've paid past debts), your income (whether you can afford the monthly payment), your down payment (how much of your own money you're putting in), and the property itself (whether it's worth what you're borrowing). Most lenders also run a background check and verify your employment. The process typically takes 30 to 45 days from process to closing.

The largest barrier for most people is the down payment. Conventional mortgages — the kind offered by banks and mortgage companies — usually require between 3 and 20 percent of the home's purchase price upfront. A $300,000 home with a 10 percent down payment means you need $30,000 in cash before you can borrow the rest. Government-backed loans like FHA mortgages allow down payments as low as 3.5 percent, but they come with additional insurance costs and stricter rules about the property.

Key Takeaways

  • Lenders examine your credit score, income, down payment amount, and the property's value — not just one of these factors.
  • Most conventional mortgages require a down payment of at least 3 to 20 percent of the home price, paid from your own funds.
  • Your debt-to-income ratio (how much you owe monthly compared to what you earn) must usually stay below 43 to 50 percent for approval.
  • The mortgage process involves a pre-qualification conversation, a formal process, an appraisal, underwriting review, and a final closing — each step takes days or weeks.
  • Different loan types (conventional, FHA, VA, USDA) have different down payment rules, credit score minimums, and property requirements.

Credit score and debt-to-income ratio: the two numbers lenders use to filter

Your credit score is a three-digit number that summarizes your borrowing history. It ranges from 300 to 850. Most conventional lenders want a score of at least 620, though scores above 740 get better interest rates. Your score comes from three credit bureaus — Equifax, Experian, and TransUnion — and reflects whether you've paid bills on time, how much debt you're carrying, and how long you've had credit accounts open.

Your debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes to debt payments. If you earn $5,000 a month and pay $2,000 toward car loans, credit cards, and student loans, your DTI is 40 percent. Most lenders cap the new mortgage payment at a DTI of 43 percent, meaning your total monthly debt (including the new mortgage) cannot exceed 43 percent of your gross income. Some lenders go up to 50 percent for borrowers with strong credit and savings.

You can improve both numbers before explore. Paying down credit card balances lowers your DTI when ready. Paying bills on time for several months raises your credit score gradually. Disputing errors on your credit report — which you can do for free through AnnualCreditReport.com — can remove inaccurate negative marks.

The mortgage process and pre-qualification process

Most people start with a pre-qualification, an informal conversation with a lender where you describe your income, debts, and down payment. The lender tells you roughly how much you could borrow. This takes minutes and requires no documents. It's useful for knowing your budget before house hunting, but it's not a promise — the lender hasn't verified anything yet.

Once you find a home and make an offer, you move to the formal mortgage process. You fill out a standardized form (the Uniform Residential Loan process, or Form 1003) and provide documents: recent pay stubs, W-2s from the past two years, bank statements showing your down payment funds, a list of debts, and permission for the lender to pull your credit report. Self-employed borrowers need two years of tax returns and sometimes profit-and-loss statements.

The lender orders a property appraisal — a licensed appraiser visits the home and compares it to similar recent sales in the area to confirm it's worth what you're paying. If the appraisal comes in low, you either renegotiate the price, increase your down payment, or walk away. The appraisal usually takes one to two weeks and costs $400 to $600, paid by you upfront.

Underwriting: where the lender verifies everything

After you submit your process and documents, an underwriter — a person employed by the lender — reviews everything. They verify your employment by contacting your employer directly. They confirm your bank balances match what you claimed. They check that your down payment came from your own savings, not from a loan (lenders want to know you have skin in the game). They review your credit report for recent late payments or new debt you didn't disclose.

The underwriter usually finds gaps or inconsistencies and sends you a list of conditions — requests for more documents or explanations. Common requests include a letter explaining a late payment, proof that you paid off a debt, or clarification about a deposit in your bank account. You have a few days to respond. This back-and-forth can add a week or two to the timeline.

Once the underwriter is satisfied, they issue clear to close — permission for the lender to fund the loan. At this point, the loan is locked in (assuming you haven't changed jobs or taken on new debt). The title company prepares closing documents, and you schedule a closing appointment.

Conventional, FHA, VA, and USDA loans: which type fits your situation

Conventional mortgages are offered by banks and mortgage companies without government backing. They typically require a credit score of 620 or higher, a down payment of at least 3 percent, and proof of stable income. If your down payment is less than 20 percent, you'll pay private mortgage insurance (PMI) — an extra monthly fee that protects the lender if you default. PMI usually costs 0.5 to 1.5 percent of the loan amount per year, added to your monthly payment.

FHA loans are backed by the Federal Housing Administration and allow down payments as low as 3.5 percent and credit scores as low as 580. The trade-off is that FHA loans require mortgage insurance no matter your down payment size, and the insurance premium is typically higher than PMI on conventional loans. FHA loans also have stricter rules about the property — it must meet safety and livability standards, and you cannot buy a home in a flood zone without additional insurance.

VA loans are for military members, veterans, and surviving spouses. They require no down payment and no mortgage insurance, but you must have a Certificate of may be able to access from the Department of Veterans Affairs. USDA loans are for rural homebuyers with moderate incomes. They also require no down payment but are limited to properties in designated rural areas.

Interest rates, loan terms, and closing costs

Your interest rate is the percentage of the loan amount you pay annually to borrow the money. Rates change daily based on market conditions and the Federal Reserve's actions. Your personal rate depends on your credit score, down payment size, loan type, and loan term. A borrower with a 750 credit score and 20 percent down might get a rate of 6.5 percent, while a borrower with a 620 score and 3 percent down might pay 7.5 percent for the same loan amount.

Most mortgages are either 15-year or 30-year loans. A 15-year mortgage has a higher monthly payment but you pay less interest overall. A 30-year mortgage has a lower monthly payment but costs more in total interest. Some lenders offer 10-year, 20-year, or 40-year terms, but 15 and 30 are standard.

Closing costs are fees charged by the lender, title company, and other parties involved in the transaction. They typically range from 2 to 5 percent of the loan amount — on a $300,000 loan, that's $6,000 to $15,000. Closing costs include the appraisal fee, title search, title insurance, loan origination fee, underwriting fee, and property taxes and insurance prorated to your closing date. You receive a Loan Estimate within three days of explore, which itemizes all expected costs. You receive a Closing Disclosure at least three days before closing, which shows the final numbers.

What can disqualify you or delay approval

Recent late payments (within the past two years) are a major red flag. A 30-day late payment on a credit card or mortgage is recoverable with explanation, but a 60-day or 90-day late payment makes approval much harder. Foreclosures and bankruptcies require a waiting period — typically three years after a foreclosure and two to four years after a bankruptcy discharge, depending on the loan type.

New debt taken on during the mortgage process can kill your approval. If you finance a car or open a credit card after submitting your process, your DTI rises and you may no longer may have access to. Job changes are also risky — if you change employers or industries, the underwriter may ask for additional documentation to confirm your income will continue. Quitting your job before closing is grounds for the lender to withdraw the offer.

Large unexplained deposits in your bank account raise questions. The underwriter needs to know where your down payment came from. If you received a gift from a family member, you'll need a signed gift letter stating it doesn't have to be repaid. If you sold something or received a bonus, you'll need documentation.

Frequently Asked Questions

How much house can I afford?

A common rule is that your monthly mortgage payment should not exceed 28 percent of your gross monthly income. On a $5,000 monthly income, that's roughly $1,400. Use an online mortgage calculator to see what loan amount that translates to in your area, accounting for your down payment, local interest rates, and property taxes. Remember this is a ceiling, not a target — you may be comfortable with less.

Should I get pre-approved before house hunting?

Yes. Pre-approval involves submitting documents and having the lender verify your income and credit, so you receive a written commitment for a specific loan amount. It shows sellers you're a serious buyer and prevents you from falling in love with a house you can't actually afford. Pre-approval is valid for 60 to 90 days.

What's the difference between a fixed-rate and adjustable-rate mortgage?

A fixed-rate mortgage has the same interest rate for the entire loan term — 15 or 30 years. Your monthly payment never changes. An adjustable-rate mortgage (ARM) has a low fixed rate for an initial period (typically three to seven years), then the rate adjusts annually based on market conditions. ARMs are riskier because your payment can increase significantly after the fixed period ends, but they offer a lower initial rate.

Can I pay off my mortgage early without penalty?

Most mortgages have no prepayment penalty, meaning you can pay extra toward principal or pay off the loan entirely without fees. Paying extra principal shortens your loan term and saves you interest. Check your loan documents or ask your lender to confirm there's no prepayment penalty before signing.

What happens if the appraisal comes in lower than the purchase price?

You have three options: renegotiate the home price down to the appraised value, increase your down payment to cover the gap, or walk away. The lender will not lend more than the appraised value, so if you want to proceed at the original price, you must make up the difference in cash.
