Buying your first home is exciting — but also overwhelming. One of the biggest questions first-time buyers face is: how much house can I actually afford?
Before you fall in love with a listing, it’s critical to understand your numbers. A realistic budget helps you stay financially secure while enjoying your new home with peace of mind.
The 28/36 Rule: Your Starting Point
Lenders often use the 28/36 rule to determine affordability:
- 28% of your gross monthly income can go toward housing costs (principal, interest, taxes, insurance — known as PITI)
- 36% of your gross monthly income can go toward total debt (housing + other debt like car payments, credit cards, student loans)
Let’s say your household income is $6,000/month:
- 28% = $1,680 available for housing
- 36% = $2,160 total debt cap
If your student loans and car payment total $500/month, that leaves about $1,660/month available for your mortgage.
Down Payment: What Can You Contribute?
The more you put down, the less you'll borrow — and the more affordable your monthly payment will be. Common down payment levels include:
- 3%: Conventional first-time buyer loans
- 3.5%: FHA loans
- 0%: VA and USDA loans (for qualified buyers)
- 10–20%: Conventional loans with no mortgage insurance
Pro Tip: Many state and local programs offer down payment assistance for first-time buyers.
How Your Credit Score Affects Affordability
Your credit score impacts your interest rate — which affects how much house you can afford. A better score = lower rate = lower monthly payment.
- 740+ = best rates
- 680–739 = competitive
- 620–679 = may qualify but at higher rates
- <620 = work on improving your credit before applying
Even a 0.5% change in interest rate can affect your buying power by tens of thousands of dollars.
Other Monthly Costs to Consider
Your mortgage payment isn't the only cost of owning a home. Make sure your budget also includes:
- Property Taxes – Varies by location (can range from $1,500 to $8,000/year)
- Homeowners Insurance – Typically $600–$1,200/year
- Mortgage Insurance – Required if putting down <20%
- HOA Fees – Common with condos and planned communities
- Utilities & Maintenance – Heating, cooling, water, repairs, landscaping, etc.
How Much Should I Have in Savings?
In addition to your down payment and closing costs, aim to have an emergency fund:
- 3–6 months of expenses in savings
- Extra funds for moving, furniture, deposits, etc.
Don’t drain your savings just to buy — you’ll want cushion after you move in.
Use Mortgage Calculators — Carefully
Online mortgage calculators can help you estimate your payment. Make sure yours includes:
- Taxes
- Insurance
- PMI (if applicable)
- HOA fees
We recommend starting with a conservative budget. Once you get pre-approved, you’ll have more clarity on what’s realistic.
How Pre-Approval Helps Clarify Affordability
Getting pre-approved by a lender gives you:
- A clear price range you qualify for
- An estimate of your monthly payment
- Proof to sellers that you're a serious buyer
You can still buy under your max approval amount — and many buyers do. Just because you qualify for a $400,000 loan doesn’t mean you should use it all.
Examples of Affordability
Let’s say your monthly housing budget is $1,600:
- With a 7% interest rate, that might afford a $240,000 home with 3% down
- At a 6% rate, your buying power could increase to $260,000–$270,000
Tip: Use a DPA program to cover the down payment and put more toward closing costs or savings.
Conclusion: Buy What You Can Comfortably Afford
Your first home should bring stability, not stress. Focus on monthly comfort, not just what the lender says you “can” buy. Set a budget that allows you to:
- Build emergency savings
- Invest in home maintenance
- Still enjoy your lifestyle
