❓ Housing Affordability Calculator FAQ
What is the 28/36 rule?
The 28/36 rule is a common guideline used by lenders to determine how much mortgage you can afford. It states that your housing expenses should not exceed 28% of your gross monthly income, and your total debt payments (including housing) should not exceed 36% of your gross monthly income.
What is the difference between front-end and back-end ratios?
The front-end ratio (housing ratio) is the percentage of your gross monthly income that goes toward housing expenses , mortgage principal, interest, taxes, and insurance (PITI). The back-end ratio (debt-to-income ratio) is the percentage of your gross monthly income that goes toward all debt payments, including housing, car loans, student loans, and credit cards.
What is PITI?
PITI stands for Principal, Interest, Taxes, and Insurance. It's the total monthly cost of owning a home, including the mortgage payment (principal and interest), property taxes, and homeowners insurance.
How much house can I afford with a $75,000 salary?
With a $75,000 annual income ($6,250/month), the 28/36 rule suggests you can afford a monthly housing payment of up to $1,750 (28% of $6,250) and total debt payments of up to $2,250 (36% of $6,250). Assuming a 6.5% interest rate, 30-year loan, 20% down, 1.2% property tax, and $1,200/year insurance, you could afford approximately $250,000–$280,000 home.
What if my DTI is higher than 36%?
Some lenders may approve loans with a DTI up to 43% or even 50% with strong compensating factors like a high credit score or significant cash reserves. However, a higher DTI means you'll have less financial flexibility and may struggle with unexpected expenses.
What is a good down payment?
A 20% down payment is traditional because it helps you avoid private mortgage insurance (PMI). However, many loans allow down payments as low as 3.5% (FHA) or 3% (conventional).
What are property taxes and how do they affect affordability?
Property taxes are annual taxes paid to local governments based on your home's value. They typically range from 0.5% to 2.5% of the home's value. Higher property taxes increase your monthly payment and reduce the home price you can afford.
Does this calculator include PMI?
This calculator does not automatically include PMI (Private Mortgage Insurance). If your down payment is less than 20%, you may need to add PMI to your monthly payment. Consult your lender for accurate PMI costs.
How accurate is this calculator?
This calculator provides accurate estimates based on standard financial formulas and the 28/36 rule. However, actual mortgage qualification depends on your credit score, lender requirements, and other factors. Use this as a planning tool and consult a mortgage lender for a precise pre-approval.
