Understanding Home Affordability

How Much House Can You Afford?

Home affordability depends on your income, debts, down payment, mortgage rates, property taxes, and insurance. Lenders use key ratios to determine how much they will lend.

The 28/36 Rule

Spend no more than 28% of gross monthly income on housing costs and no more than 36% on total debt. This helps ensure you do not become house poor.

Down Payment Impact

A larger down payment reduces your loan amount, monthly payment, and may eliminate PMI. Many programs allow 3-5% down.

Hidden Costs

Budget for property taxes, insurance, maintenance (1-2% of home value/year), HOA fees, and utilities.

Interest Rate Sensitivity

A 1% rate increase on a $300,000 loan adds roughly $200/month. Over 30 years that is over $70,000 in additional interest.

Practical Example

With $80,000 annual income, $40,000 down payment, $500/month debts, and 7% rate on a 30-year term.

Using the 28/36 rule, the maximum home price would be approximately $220,000-$250,000 depending on local tax rates.

Frequently Asked Questions

What is a good DTI ratio for a mortgage?

Most lenders prefer a DTI of 36% or less for total debt, and no more than 28% for housing costs alone.

How much down payment do I need?

Conventional loans require 3-20% down. FHA requires 3.5%. VA and USDA may require zero down.

Does this calculator include PMI?

This estimates principal, interest, taxes, and insurance. Add PMI separately if down payment is under 20%.

What if interest rates change?

Even 0.5% changes significantly affect affordability. Test different rate scenarios.

Should I include bonuses in my annual income?

Lenders typically use base income. Variable income may count if documented for 2+ years.
