How Affordability is Determined
Income
Your gross monthly income is the foundation of your affordability calculation. Higher income means higher purchasing power.
Debt-to-Income Ratio
Lenders use DTI to ensure you can comfortably afford your monthly payments without financial strain.
Interest Rate
Lower rates increase purchasing power; higher rates decrease it. Even small rate differences matter.
Down Payment
A larger down payment reduces your loan amount, monthly payment, and may eliminate PMI.

Frequently Asked Questions
How is mortgage affordability calculated?
Mortgage affordability is calculated based on your monthly income, monthly debt payments, down payment, interest rate, and loan term. Lenders use the 28/36 rule to determine how much you can afford: housing expenses should not exceed 28% of gross income, and total debt should not exceed 36%.
What is the 28/36 rule?
The 28/36 rule states that you should spend no more than 28% of your gross monthly income on housing expenses (PITI) and no more than 36% on total debt payments including housing.
How much house can I afford on $50k salary in 2026?
As of 2026, with a $50,000 salary ($4,167/month), you can typically afford a house in the $150,000 to $200,000 range depending on your debt and down payment. Using the 28% rule, your housing budget is about $1,167/month.
How much house can I afford on $100k salary in 2026?
With a $100,000 salary ($8,333/month), you can typically afford a house in the $400,000 to $500,000 range. At 28%, your housing budget is about $2,333/month at current 2026 interest rates.
Does credit score affect affordability?
Yes, a higher credit score (740+) can help you qualify for lower interest rates (0.5-1% lower), which increases your purchasing power by $50K or more on a typical mortgage.
How does debt affect affordability?
Monthly debt payments reduce your available housing budget. $500/month in debt could reduce your affordable home price by $80,000 or more depending on interest rates and down payment.
What is the minimum down payment?
You can put down as little as 3% with conventional loans or 3.5% with FHA loans. However, 20% down avoids PMI and is recommended for maximum purchasing power.
How much savings do I need besides the down payment?
Plan for closing costs (2-5% of purchase price), moving expenses, and 3-6 months of emergency reserves. For a $300K home, expect $6K-$15K in closing costs.
Should I include taxes and insurance in my budget?
Absolutely. Your monthly payment should include Principal, Interest, Property Taxes, and Insurance (PITI). Taxes and insurance can add $200-$500+ monthly depending on location.
Can I afford more if I have no debt?
Yes! Having no debt gives you maximum buying power. With $5,000 monthly income and no debt, you could afford a $280K-$320K home at 2026 interest rates.
How do 2026 interest rates affect affordability?
At 6.5%, $2,000/month buys ~$330K. At 7.5%, that same payment only buys ~$300K - a 9% reduction in buying power for each 1% increase in rates.
What if my DTI is too high?
If your DTI exceeds 43%, you can pay down debt, increase your down payment, extend the loan term, or look for lenders with more flexible DTI requirements.
