Home Affordability

What's Your Maximum Home Price?

The gap between what you want and what you can comfortably afford is where financial stress lives. Our calculator applies the industry-standard 28/36 lending guidelines to your income, debts, and down payment to determine the maximum home price that keeps your finances healthy — not just the maximum a bank will approve.

Enter your annual gross income, monthly debt payments (car loans, student loans, credit card minimums), available down payment, expected mortgage rate, and estimated property taxes and insurance. The calculator returns your maximum home price, maximum monthly payment, and the loan amount you'd qualify for.

Quick estimate: Multiply your annual gross household income by 3–4.5 for a rough maximum home price. A household earning $100,000 can typically afford $300,000–$450,000 depending on debt, rates, down payment, and local taxes.

The 28/36 Rule Explained

Lenders use two ratios to determine how much you can borrow. The front-end ratio (28%) limits your total housing payment (mortgage principal + interest + property taxes + homeowners insurance + HOA) to 28% of your gross monthly income. The back-end ratio (36%) limits your total debt payments (housing + all other debts) to 36% of gross monthly income.

Example: Household income $90,000/year ($7,500/month gross). Front-end limit: $7,500 × 0.28 = $2,100 maximum housing payment. If property taxes are $300/month and insurance $130/month, the maximum mortgage P&I payment is $2,100 - $430 = $1,670. At 6.4% for 30 years, that supports a loan of approximately $263,000. With 20% down, maximum home price is approximately $329,000.

Back-end check: If you have $400/month in car payments and $300/month in student loans, total debt = $2,100 (housing) + $700 = $2,800. Back-end limit: $7,500 × 0.36 = $2,700. You exceed the 36% ratio — the back-end constraint reduces your affordable home price until total debt fits within $2,700/month.

The 28/36 rule is a guideline, not a hard cap. Some lenders approve loans with DTIs up to 43% (the FHA's maximum) or even 50% for borrowers with strong compensating factors (high savings, excellent credit, large down payment). But qualifying for a loan and being comfortable with the payment are very different things — stretching to 43% DTI leaves little room for savings, emergencies, or lifestyle.

What Lenders Consider Beyond the Ratios

Credit score affects both approval and rate. A 780+ score qualifies for the best rates (potentially 0.5–1% lower than average). Below 620, conventional loans become difficult and FHA becomes the primary option.

Down payment affects loan size, PMI, and rate. 20% eliminates PMI ($100–$400/month savings). 10–19% requires PMI but keeps the loan manageable. 3–5% is the minimum for conventional/FHA but maximizes monthly costs.

Employment stability — lenders prefer 2+ years at the same employer or in the same field. Self-employed borrowers need 2 years of tax returns showing consistent income. Gaps in employment within the last 2 years require explanation.

Cash reserves — having 2–6 months of mortgage payments in liquid savings after closing improves approval odds and demonstrates financial stability. Some loan programs require minimum reserves.

Loan type affects affordability. FHA loans require only 3.5% down and accept credit scores as low as 580 but add mandatory mortgage insurance for the life of the loan. VA loans (veterans) require 0% down and no PMI. USDA loans (rural areas) offer 0% down. Conventional loans require 3–20% down with PMI dropping off at 20% equity.

Beyond the Calculator: Hidden Costs of Homeownership

Our calculator estimates your maximum based on PITI (principal, interest, taxes, insurance). But total homeownership costs extend further.

Maintenance: 1–2% of home value annually. A $350,000 home needs $3,500–$7,000/year set aside for repairs and upkeep. New construction needs less initially; homes 20+ years old may need more.

Utilities: Homeowners typically pay more for utilities than renters because homes are larger and you're responsible for all systems. Budget $200–$400/month depending on climate, home size, and efficiency.

HOA fees: Range from $100–$700+/month for condos and planned communities. These are mandatory and increase over time. Factor HOA into your affordability calculation — $400/month in HOA reduces your affordable mortgage payment by $400.

Closing costs: 2–5% of the loan amount, paid at purchase. On a $300,000 loan: $6,000–$15,000. This is money needed in addition to your down payment.

Furnishing and moving: A new home often needs furniture, appliances, window treatments, and other setup costs. Budget $5,000–$20,000+ depending on the home's condition and your existing furnishings.
