The 28/36 Rule: Your Starting Point
Before diving into house hunting, most mortgage lenders use the 28/36 debt-to-income (DTI) rule to determine how much you can borrow. Here's how it works: your monthly mortgage payment (principal, interest, taxes, and insurance) shouldn't exceed 28% of your gross monthly income. Additionally, your total monthly debt payments—including the new mortgage, car loans, student loans, and credit cards—shouldn't surpass 36% of your gross income.
Let's say you earn $60,000 annually, or $5,000 per month gross. Your maximum housing payment would be $1,400 (28% of $5,000). If you already have $300 in other monthly debt, your total debt payments can't exceed $1,800 (36% of $5,000), leaving $500 for the mortgage.
This rule is not guaranteed approval—it's a guideline. Some lenders are more flexible, especially for first-time buyers with excellent credit, while others are stricter. Use Our Free Calculator to see your personalized numbers based on your financial situation.
Down Payment Options for First-Time Buyers
One of the biggest hurdles for first-time homebuyers is saving for a down payment. The good news? You don't need 20% down anymore. Here are your realistic options:
| Loan Type | Minimum Down Payment | Who It's For | Key Feature |
|---|---|---|---|
| FHA Loan | 3.5% | First-time buyers, lower credit scores (580+) | Lower down payment, but requires mortgage insurance |
| VA Loan | 0% | Military members, veterans, surviving spouses | No down payment, no PMI required |
| USDA Loan | 0% | Rural or suburban homebuyers (income limits apply) | Low interest rates, 0% down |
| Conventional Loan | 3-5% | Borrowers with good to excellent credit (620+) | Flexible terms, competitive rates with PMI |
| Jumbo Loan | 10-20% | High-value home purchases ($766,550+) | For expensive properties, stricter lending |
FHA loans are particularly popular with first-time buyers because they require just a 3.5% down payment on the home price. If you're buying a $300,000 home, that's only $10,500 down. However, you'll pay for mortgage insurance premiums (MIP)—an upfront 1.75% cost and annual premiums of 0.55% to 0.8% depending on your loan amount and credit score.
If you're a veteran or active military member, VA loans offer 0% down with no mortgage insurance required, making them the most affordable option available. USDA loans are similarly generous for rural homebuyers.
Calculate Your Maximum Home Price
Here's a step-by-step breakdown of how to determine your price range:
- Determine your gross monthly income. If you earn $75,000 annually, that's $6,250 per month before taxes.
- Calculate your maximum housing payment (28% rule). $6,250 × 0.28 = $1,750 per month.
- Subtract property taxes, insurance, and HOA fees. Averages vary by state. In Texas, property taxes run ~1.6% annually; in New Jersey, ~2.15%. For a $300,000 home in Texas, annual property tax is roughly $4,800 ($400/month). Homeowners insurance averages $100-200/month.
- Calculate your principal and interest payment. Using a 30-year mortgage at 7% interest: $1,750 - $500 (taxes/insurance) = $1,250 for P&I. A $200,000 loan at 7% for 30 years = $1,331/month. So this budget supports roughly $200,000 in borrowing.
- Add your down payment. If you can put down 3.5% ($7,000), your affordable home price is approximately $207,000.

Understanding Closing Costs and Hidden Expenses
First-time buyers often forget about closing costs, which typically run 2-5% of the loan amount. On a $250,000 mortgage, expect $5,000-$12,500 in closing costs. These include:
- Origination fees: 0.5-1% charged by the lender
- Appraisal: $400-$600 to verify the home's value
- Title search and insurance: $500-$1,500 to ensure clear ownership
- Attorney fees: $500-$1,500 (required in many states)
- Home inspection: $300-$500 (optional but strongly recommended)
- Survey: $300-$500 in some cases
- Property taxes and insurance prepayment: $1,000-$3,000 (lender requirements)
Good news for first-time buyers: you may qualify for assistance programs. Many states offer down payment assistance (DPA) programs that grant $5,000-$15,000 to help with down payments and closing costs. The National Council of State Housing Finance Agencies tracks available programs by state.
Also budget for ongoing homeownership costs beyond the mortgage: property maintenance (typically 1% of home value annually), homeowners insurance ($800-$2,000+ yearly depending on location), and property taxes (varies dramatically by state—from 0.3% in Hawaii to 2.49% in New Jersey).
Credit Score, Interest Rates, and Loan Approval
Your credit score directly impacts your mortgage interest rate. Here's what you can expect in 2024 (rates fluctuate with Federal Reserve policy):
| Credit Score Range | Typical Interest Rate (30-yr Fixed)* | Monthly Payment on $250,000 Loan |
|---|---|---|
| 740-850 (Excellent) | 6.5-7.0% | ~$1,636 |
| 700-739 (Good) | 7.0-7.5% | ~$1,748 |
| 660-699 (Fair) | 7.5-8.25% | ~$1,911 |
| 580-659 (Poor) | 8.5-9.5% (FHA) | ~$2,124 |
*Rates as of early 2024; check current rates with multiple lenders
A 100-point increase in your credit score could save you $100-200+ per month—that's $36,000-$72,000 over a 30-year mortgage. Before applying, pay down existing debt, fix any credit report errors, and avoid new credit inquiries.
First-time buyer programs often relax credit requirements. FHA loans accept scores as low as 580 (with 3.5% down) or even 540 (with 10% down). VA and USDA loans are similarly flexible. However, expect higher interest rates and PMI costs at lower credit tiers.
State-by-State Variations: Why Location Matters
Your location dramatically affects affordability. Consider property taxes, insurance costs, and home prices:
- Low-tax states: Texas (avg. 1.6% property tax), Florida (0.85%), Alabama (0.41%)—great for keeping monthly payments low.
- High-tax states: New Jersey (2.15%), Illinois (1.97%), Wisconsin (1.85%)—significantly increase your total housing costs.
- High-cost markets: San Francisco, New York City, Boston, and Los Angeles have median home prices $800,000-$1,500,000+. Even with strong income, affordability is challenging.
- Affordable markets: Des Moines, Memphis, Pittsburgh, and Kansas City offer median home prices $200,000-$350,000, making homeownership accessible on middle-class incomes.
