Understanding Credit Scores and How They Work

Your credit score is a three-digit number that lenders use to understand your borrowing history. This number ranges from 300 to 850, and it reflects how responsibly you've handled credit in the past. Credit reporting agencies—Equifax, Experian, and TransUnion—collect information about your financial behavior and calculate these scores using specific factors.

The most common scoring model, called FICO, breaks down your score into five categories. Payment history makes up 35% of your score, which means paying bills on time matters most. The amount of debt you currently owe accounts for 30%. The length of your credit history represents 15%. New credit inquiries count for 10%, and the types of credit you use make up the final 10%.

A score above 670 is typically considered good, while scores below 580 are generally seen as poor by most lenders. If your score falls between 580 and 669, you're in the fair range. Many mortgage lenders prefer scores of 620 or higher, though some programs may work with lower scores. Understanding where your score stands helps you know what to expect when you contact lenders.

Your credit score can change monthly based on new information reported to the credit bureaus. Paying down debt, making on-time payments, and avoiding new accounts can help your score improve over time. However, negative items like late payments stay on your report for seven years, though their impact decreases as time passes.

Practical takeaway: Request your free credit report from all three bureaus at annualcreditreport.com. Review it for errors or unfamiliar accounts, and note your current score range. This gives you a baseline for understanding what lenders might see about your credit history.

Steps to Improve Your Credit Profile Before Seeking a Mortgage

Before talking to mortgage lenders, you can take several steps to strengthen your credit profile. The most important action is making all payments on time, starting immediately. Even one late payment can lower your score by 100 points or more. Set up automatic payments or calendar reminders to ensure you never miss a due date on any account—credit cards, loans, utilities, or medical bills.

Paying down existing debt is your second priority. When you owe less money relative to your credit limits, your "credit utilization ratio" improves. For example, if you have a $5,000 credit card limit and owe $4,500, your utilization is 90%—considered high. Paying that balance down to $1,500 brings your utilization to 30%, which looks much better to lenders. Aim to use no more than 30% of your available credit across all accounts.

Avoid opening new credit accounts while you're preparing for a mortgage. Each new account triggers a hard inquiry, which temporarily lowers your score. Additionally, new accounts lower your average account age, and lenders want to see established credit history. Wait until after your mortgage is approved before opening new credit cards or loans.

If you have accounts that have been delinquent, bringing them current should be a priority. Paying off old collection accounts may not remove them from your report, but it shows lenders you've addressed the problem. Some lenders care more about recent payment patterns than old negative items.

Consider becoming an authorized user on someone else's account with good payment history. This can add positive credit history to your report, though some lenders view this differently. Alternatively, if you have no credit history at all, secured credit cards—where you deposit money as collateral—can help you build credit over time.

Practical takeaway: Create a three-month action plan. Month one: set up automatic payments and pay down your highest credit utilization accounts. Month two: continue payments and bring any delinquent accounts current. Month three: review your credit report again to see improvement before contacting lenders.

Mortgage Basics: Types of Loans and How They Differ

Mortgages come in several types, and understanding the differences helps you explore which might work for your situation. The most common type is the conventional loan, which comes from private lenders and typically requires a down payment of 3% to 20% of the home's purchase price. These loans follow guidelines set by lending companies rather than government agencies.

Federal Housing Administration (FHA) loans are insured by the government, which means lenders accept lower credit scores and smaller down payments—sometimes as little as 3.5%. This makes FHA loans a real option for people with credit challenges or limited savings. However, FHA loans require mortgage insurance premiums, which add to your monthly payment cost.

VA loans are available to military service members, veterans, and surviving spouses. These government-backed loans often require no down payment and have competitive interest rates. USDA loans serve people in rural areas and also may require no money down. Each loan type has different requirements and benefits.

Loans also differ in how interest rates work. Fixed-rate mortgages keep the same interest rate for the entire loan term—typically 15, 20, or 30 years. Your monthly payment stays the same throughout. Adjustable-rate mortgages (ARMs) start with a lower interest rate that changes after a set period, usually causing your payment to increase. ARMs can be risky if you plan to stay in the home long-term, since rates could rise significantly.

The loan term matters too. A 30-year mortgage has lower monthly payments but costs more in total interest. A 15-year mortgage has higher monthly payments but builds equity faster and costs less overall. Some people choose a middle ground with a 20-year term.

Practical takeaway: List your priorities: How long do you plan to stay in the home? Can you afford higher monthly payments for a shorter loan? Do you have military service or live in a rural area? These answers help point toward loan types worth exploring with lenders.

Income, Employment, and What Lenders Review

Mortgage lenders examine your income carefully because they need to know you can make monthly payments. Most lenders use a debt-to-income (DTI) ratio to measure this. DTI compares your monthly debt payments to your gross monthly income. For example, if you earn $5,000 per month and have $1,500 in monthly debt payments, your DTI is 30%. Most lenders want to see DTI ratios below 43%, though some may accept up to 50% for borrowers with strong credit.

Lenders accept several types of income. W-2 employment income from a traditional job is the easiest to document—lenders simply review your recent pay stubs and tax returns. Self-employment income, freelance work, and business income require more documentation, typically two years of tax returns showing consistent or growing earnings. Some lenders worry that self-employment income is less stable, so they may scrutinize it more closely.

Other income sources may count too. Retirement income, Social Security, child support, alimony, and rental income can all factor into your total income, though lenders usually require documentation like bank statements, tax returns, or award letters. Overtime and bonus income may be included if you have a history of receiving it—usually two years of records showing consistency.

Employment history matters as well. Lenders generally want to see two years of steady work history. If you've changed jobs recently, you'll need to explain the move. Job changes within the same industry or field usually raise fewer concerns than complete career shifts. If you have gaps in employment, be prepared to document what happened and why.

Lenders will verify your employment by contacting your employer directly. Some may call during the mortgage approval process to confirm you still work there. This is another reason to avoid changing jobs while your mortgage is being processed—it can complicate the verification.

Practical takeaway: Calculate your DTI ratio now. Add up all monthly debt payments (credit cards, student loans, car loans, child support) and divide by your gross monthly income. If it's above 43%, focus on paying down debt or increasing income before contacting lenders. Gather two years of recent pay stubs and tax returns to have ready.

Down Payments, Savings, and Affording Homeownership Costs

Your down payment is the money you put toward purchasing the home upfront. The remaining amount becomes your mortgage loan. Down payments range from 0% to 20%
