Things to consider before applying for a mortgage loan

Key takeaways 

• Your credit score, debt load and savings don’t just determine whether you qualify — they shape your rate and monthly payment. Taking a close look at all three upfront helps you zero in on what you can realistically afford.
• The mortgage isn’t the full picture. Once you factor in taxes, insurance, utilities and upkeep, the true cost of owning a home can run roughly 30% to 45% higher than the loan payment alone.
• It pays to shop around. Getting loan estimates from at least three lenders and comparing rates, fees and discount points is one of the simplest ways to cut your total borrowing cost.

Before applying for a mortgage, borrowers should assess several factors that will shape both approval and long-term cost. Credit profile, debt load, savings and loan program all influence the terms a lender will offer.

This guide outlines the financial and personal considerations to weigh before starting the application process.

Readiness depends on both financial stability and a realistic plan to stay in the home for at least three to five years.

From a lender’s perspective, that typically includes a steady employment history, often two years, income that covers existing obligations and savings beyond what is required at closing.

That also means maintaining an emergency fund equal to three to six months of living expenses, separate from your down payment. Without that cushion, an unexpected repair or income disruption soon after purchase can strain your finances.

Personal timing matters as well. If a job change, relocation or other major shift is likely, renting may offer more flexibility. Buying involves upfront costs and front-loaded interest payments, making it less advantageous over shorter time horizons. A common benchmark is to remain in the home for at least five years, though that period can extend depending on mortgage rates and local conditions.

In practice, buying tends to make the most sense when financial stability and long-term plans are aligned.

For a clearer picture of where you stand, evaluate your financial position before contacting lenders.

The amount a lender is willing to approve and what fits comfortably within your budget are often different. Lenders use your debt-to-income ratio, or DTI, to set borrowing limits, but your actual budget should reflect the full cost of ownership.

A widely used guideline, known as the 28/36 rule, limits housing costs to 28% of gross monthly income and total debt obligations to 36%. Many loan programs allow higher ratios. For example, Federal Housing Administration (FHA) guidelines extend to 43%, and automated underwriting for conventional loans can approve ratios near 50% with strong compensating factors. Higher ratios, however, leave less room for other expenses.

The real cost goes beyond principal and interest.

Depending on location and property type, the mortgage payment may account for only 60% to 70% of total housing costs. Before settling on a price range, factor in:

• Property taxes, which vary widely by location and often range from 0.5% to 2% of a home’s value annually
• Homeowners insurance
• Private mortgage insurance if the down payment is below 20%
• Homeowner association (HOA) fees, if applicable
• Utilities, including electric, gas, water, trash and internet
• Maintenance, commonly estimated at 1% to 4% of the home’s value per year, with newer homes typically on the lower end

These expenses are often underestimated early in the process. Using a mortgage calculator to model different scenarios can help set a more realistic price range.

Minimum requirements vary by loan type. Conventional loans typically require a 620 credit score. Federal Housing Administration loans accept scores as low as 580 with 3.5% down, or 500 with 10% down. The Department of Veterans Affairs sets no official minimum, though many lenders look for scores between 580 and 620.

In addition to eligibility, credit score directly influences loan pricing. For conventional loans, lenders apply loan-level pricing adjustments that increase costs for lower-score borrowers. A buyer with a 660 score may receive a higher rate than one with a 740 score on the same loan.

Government-backed loans, including FHA and VA, generally rely less on these layered adjustments. As a result, borrowers with lower scores may find those programs more competitive on a monthly basis.

Things to consider before you apply

• Pull credit reports from Equifax, Experian and TransUnion at AnnualCreditReport.com and dispute errors
• Reduce revolving balances to below 30% of available credit
• Avoid opening new accounts in the months before applying
• Keep existing accounts open to preserve credit history

Down payment requirements range from 0% for VA and USDA loans to 20% for conventional loans to avoid mortgage insurance. Closing costs typically add another 2% to 5% of the loan amount. Conventional loans may require as little as 3% down, while FHA loans require 3.5% for eligible borrowers.

Your down payment influences ongoing costs. A conventional loan with less than 20% down requires private mortgage insurance, which increases monthly expenses. That cost should be weighed against the benefit of preserving liquidity.

At the same time, allocating too much cash to the down payment can leave you under-reserved. Maintaining an emergency fund is generally more important than eliminating mortgage insurance.

Down payment assistance programs are available at the state and local level, and some lenders and nonprofits offer additional options. Gift funds from family members may also be used if documentation requirements are met. Both are worth exploring well in advance.

The right loan depends on credit profile, savings and eligibility.

Note: Loans backed by the Department of Veterans Affairs do not require mortgage insurance but include a one-time funding fee, typically 1.25% to 3.3% of the loan amount. This fee may be waived for veterans with a service-connected disability.

Understanding which programs you qualify for helps set realistic expectations around savings and credit.

Pre-qualification provides a rough estimate based on self-reported information. Pre-approval requires a lender to verify income, assets and credit and issue a conditional commitment for a specific loan amount.

For buyers preparing to make offers, pre-approval carries more weight because it signals to sellers that financing has already been vetted.

Lenders typically request documentation of identity, income, assets and debts. Requirements vary by employment type and loan program. Self-employed borrowers often need additional records, such as profit-and-loss statements and business tax returns.

Standard documents you’ll need:

• Tax returns for the last two years
• Pay stubs for the last one to two months
• Several recent bank statements
• Proof of other income if you’re using it in your application

Sometimes, you might need additional documents as well if you have a less-common situation:

• Military service records and/or certificate of eligibility for VA loans
• 1099s and additional tax returns if you’re self-employed
• Gift letters if you’re using gift money for your down payment

Comparing lenders can materially affect the total cost of the loan. Request loan estimates from at least three lenders and review them side by side.

The interest rate provides only part of the picture. The annual percentage rate, or APR, incorporates fees and offers a clearer measure of total cost.

What to look at on the loan estimate

• APR, which provides the most consistent basis for comparison
• Origination charges and lender fees
• Discount points, which lower the rate in exchange for upfront cost
• Third-party fees, such as appraisal and title charges

Once you select a lender, you can lock the interest rate for a specified period, typically 30 to 60 days, to protect against market movement during processing. Confirm the lock period and any extension terms.

After applying, the priority is consistency. Lenders re-verify finances before closing, and changes can affect approval.

Common pitfalls include:

• Opening new credit accounts or co-signing loans
• Making large purchases that increase debt
• Changing jobs without informing the lender
• Depositing large sums without documentation
• Closing existing credit accounts

Keeping your financial profile stable through closing reduces the risk of delays or revisions to the loan.

Does checking my own credit score hurt my chances of getting a mortgage?

No. Checking your own credit is a soft inquiry and does not affect your score. Hard inquiries occur only when a lender reviews your credit as part of an application. Mortgage inquiries made within a defined window are typically treated as a single inquiry.

What happens if your financial situation changes after pre-approval?

Lenders re-verify finances before closing. A decline in income, new debt or a lower credit score can lead to revised terms, a reduced loan amount or a denial during final underwriting.

Can I apply for a mortgage if I have student loan debt?

Yes. Student loan payments are included in your DTI, but they do not automatically disqualify you. Staying within program limits is what matters.

Do I need a real estate agent before getting pre-approved?

No. Many buyers seek pre-approval first to establish a price range before beginning their home search.
