First-Time Home Buyer Guide 2026: How Much House Can You Afford?
Quick Answer
Most lenders recommend spending no more than 28% of your gross monthly income on housing costs (mortgage, taxes, insurance). On a $75,000 salary, that's roughly $1,750/month, which supports a home price around $275,000–$325,000 depending on your down payment, interest rate, and location. But what you qualify for and what you can comfortably afford are often very different numbers.
The 28/36 Rule
Lenders use two ratios to decide how much to lend you:
Front-end ratio (28%): Your total housing costs — mortgage payment, property taxes, homeowner's insurance, and HOA fees — should not exceed 28% of your gross monthly income.
Back-end ratio (36%): Your total monthly debt payments — housing costs plus car loans, student loans, credit cards, and other debts — should not exceed 36% of gross monthly income.
Example: On $80,000/year ($6,667/month gross):
- Max housing payment: $1,867 (28%)
- Max total debt: $2,400 (36%)
- If you have $400/month in car + student loan payments, your max housing drops to $2,000
How Much Down Payment Do You Need?
The 20% down payment rule is a myth for first-time buyers. Here are your actual options:
Conventional loan: As low as 3% down. On a $300,000 home, that's $9,000 instead of $60,000. You'll pay Private Mortgage Insurance (PMI) of roughly $100–$250/month until you reach 20% equity.
FHA loan: 3.5% down with a credit score of 580+. More lenient credit requirements, but you'll pay mortgage insurance for the life of the loan (unless you refinance later).
VA loan: 0% down for eligible veterans and active military. No PMI. This is the single best mortgage product available — see our VA Loan Benefits guide.
USDA loan: 0% down for homes in eligible rural and suburban areas. Income limits apply, but they're higher than you'd expect.
According to data from the National Association of Realtors, the median down payment for first-time buyers was 8% in recent years — not 20%.
The True Cost of Buying a Home
The purchase price is just the beginning. Budget for these additional costs:
Closing Costs (2–5% of purchase price)
- Loan origination fees
- Appraisal and inspection
- Title insurance
- Attorney fees
- Prepaid property taxes and insurance
On a $300,000 home, expect $6,000–$15,000 in closing costs. Some can be negotiated or rolled into the loan.
Ongoing Costs Beyond the Mortgage
- Property taxes: Vary dramatically by location (0.3% in Hawaii to 2.5% in New Jersey)
- Homeowner's insurance: $1,500–$3,000/year average
- Maintenance: Budget 1% of home value per year ($3,000/year on a $300K home)
- HOA fees: $200–$500/month in communities with shared amenities
- Utilities: Often higher than renting, especially for larger homes
Step-by-Step: From Browsing to Keys
Step 1: Check your credit score. Aim for 700+ for the best rates. Every 20-point improvement can save thousands over the life of your loan. You can check for free at AnnualCreditReport.com.
Step 2: Get pre-approved (not pre-qualified). Pre-approval means a lender has verified your income, assets, and credit. It shows sellers you're serious and tells you exactly how much you can borrow.
Step 3: Determine your comfortable budget. Just because you're approved for $400K doesn't mean you should spend $400K. Use the 28% rule on your take-home pay (not gross) for a more comfortable target.
Step 4: Find a buyer's agent. A good agent knows the local market, negotiates on your behalf, and guides you through the process. Their commission is typically paid by the seller.
Step 5: House hunt with discipline. Set a hard budget ceiling before you start looking. It's easy to fall in love with a home $50K above your budget — that's an extra $300/month for 30 years.
Step 6: Make an offer and negotiate. Your agent will help you craft a competitive offer. In most markets, there's room to negotiate on price, closing costs, or repairs.
Step 7: Complete inspections. Never skip the home inspection ($300–$500). It can reveal $10,000+ in hidden problems. Also consider radon testing, pest inspections, and sewer line scopes.
Step 8: Close the deal. Final walkthrough, sign paperwork, get keys. Budget 2–4 hours for closing day.
Common First-Time Buyer Mistakes
Buying the most you qualify for. Lenders will approve you for more than you can comfortably afford. They don't factor in your lifestyle, savings goals, or irregular expenses. Stay at least 10–15% below your max approval.
Ignoring total monthly costs. A $1,800 mortgage payment becomes $2,500 when you add taxes, insurance, PMI, and HOA. Always calculate the full PITI (Principal, Interest, Taxes, Insurance).
Draining your emergency fund for the down payment. You should have 3–6 months of expenses saved after closing, not before. Homeownership comes with surprise costs — the furnace, the roof, the plumbing.
Skipping the inspection to win a bidding war. In competitive markets, buyers sometimes waive inspections. This is extremely risky. A major structural issue can cost $50,000+ to fix.
Not shopping mortgage rates. According to the Consumer Financial Protection Bureau, comparing just three lenders can save you more than $3,500 over the first five years of a mortgage. Always get multiple quotes.
Rent vs Buy: When Does Buying Make Sense?
Buying isn't always better than renting. Consider buying when:
- You plan to stay in the area for 5+ years
- Your total housing costs (PITI) are within 10–15% of equivalent rent
- You have a stable income and emergency fund
- You're not carrying high-interest debt

FAQ
How much should I save before buying my first home?
Aim for: down payment (3–20% of purchase price) + closing costs (3–5%) + moving costs ($2,000–$5,000) + emergency fund (3–6 months expenses). For a $300K home with 5% down, that's roughly $15,000 + $12,000 + $3,000 + $15,000 = $45,000.
Is it better to buy with a 15-year or 30-year mortgage?
A 30-year mortgage has lower monthly payments, giving you more flexibility. A 15-year mortgage saves significantly on interest but requires about 40% higher monthly payments. Most first-time buyers choose 30-year for the lower payments, then make extra payments when possible.
What credit score do I need to buy a house?
FHA loans require a minimum 580 score (3.5% down) or 500 (10% down). Conventional loans typically need 620+. But for the best rates, aim for 740+. Each tier improvement saves you meaningful money over 30 years.
Should I pay points to lower my interest rate?
Paying points (prepaid interest) lowers your rate but costs 1% of the loan amount per point. It makes sense if you'll stay in the home long enough to recoup the upfront cost — typically 5–7 years. Our mortgage calculator can model this for you.
