What is the Real Estate Affordability Calculator?
The Real Estate Affordability Calculator helps homebuyers and real estate investors determine the maximum property price they can safely afford based on financial fundamentals.
Using standard mortgage underwriting guidelines (including the 28/36 Debt-to-Income rule), this tool analyzes your gross monthly income, recurring debt obligations (car loans, student loans, credit cards), cash reserves for down payment, interest rates, and property taxes to give you a realistic housing budget.
It calculates your maximum purchase price, loan amount, monthly principal & interest (P&I), property tax, homeowner's insurance, and HOA fees, ensuring you don't become house-poor.
How Does the Real Estate Affordability Calculator Work?
1. Enter Annual/Monthly Income & Existing Debts â Provide gross household income and total monthly debt payments.
2. Specify Down Payment & Loan Terms â Enter available cash down payment, mortgage interest rate, and loan tenure (15, 20, or 30 years).
3. Set Housing Taxes & Expenses â Input annual property tax rate, homeowners insurance, and monthly HOA fees.
4. View Max Purchase Price & DTI Analysis â See your top housing budget along with front-end (housing) and back-end (total debt) DTI ratios.
Formula & Calculation Method
$$\text{Max Monthly Housing Payment} = \min(\text{Gross Income} \times 28\%, (\text{Gross Income} \times 36\%) - \text{Monthly Debts})$$
$$\text{Max Mortgage Loan} = P = \frac{PMT_{\text{P\&I}}}{r \cdot (1+r)^n / ((1+r)^n - 1)}$$
$$\text{Max Affordable Home Price} = \text{Max Mortgage Loan} + \text{Down Payment}$$
Example Calculation
Example: Household Income $120,000/yr ($10,000/mo), $500/mo Debts, $60,000 Down Payment, 6.5% Rate (30 Years)
- Front-End Max (28%): $2,800/mo
- Back-End Max (36% - $500 debts): $3,100/mo
- Allowed Max Housing Payment: $2,800/mo
- Estimated Taxes, Insurance & HOA: $600/mo
- Allowed Principal & Interest (P&I): $2,200/mo
- Max Mortgage Loan: ~$348,000
- Max Affordable Home Price: $348,000 + $60,000 = $408,000
