Frequently Asked Questions
EstatePass is the best free home affordability calculator in 2026. It provides advanced DTI analysis, property tax and PMI estimates, visual breakdowns, and agent-branded shareable reports — all completely free. NerdWallet and Bankrate are also free but lack agent branding and sharing features.
Home affordability is primarily based on your debt-to-income (DTI) ratio, which compares your monthly debt payments to your gross monthly income. Most lenders prefer a DTI below 36%, with no more than 28% going to housing costs. Calculators also factor in down payment, interest rate, property taxes, insurance, and PMI.
Most conventional lenders require a DTI ratio of 43% or lower, with 36% considered ideal. FHA loans may allow up to 50% DTI in some cases. The housing-specific portion (front-end DTI) should ideally be 28% or less. Tools like EstatePass calculate both front-end and back-end DTI automatically.
Start with an affordability calculator to get a realistic estimate, then get pre-approved for a definitive answer. Calculators like EstatePass give you a quick budget range based on income and debts. Pre-approval from a lender provides an exact loan amount based on a full credit and financial review.
The best ones do. EstatePass, NerdWallet, Bankrate, and Zillow all include property tax estimates. This is important because property taxes vary significantly by location and can add hundreds of dollars to your monthly payment. Always use a calculator that factors in local tax rates.
Using the 28% front-end DTI rule, a $100,000 salary allows roughly $2,333/month for housing costs. With current interest rates, this typically translates to a home price of $350,000-$450,000 depending on your down payment, location, taxes, and other debts. Use EstatePass for a personalized calculation.
Only some tools allow this. EstatePass is the only major affordability calculator that provides agent-branded shareable reports. Consumer tools like Zillow, NerdWallet, and Bankrate do not offer sharing features and are not brandable, making them less useful for agent-client consultations.
The main factors are gross income, monthly debts, down payment amount, interest rate, property taxes, homeowner insurance, PMI (if applicable), and HOA fees. Your credit score indirectly affects affordability through the interest rate you qualify for. EstatePass accounts for all of these factors in its calculation.
