What Drives Your Budget
Key Factors That Affect Affordability
๐
Debt-to-Income Ratio (DTI)
Most lenders want total monthly debts (including new mortgage) below 43% of gross income. The lower your DTI, the more you can borrow.
๐ฐ
Down Payment
Larger down = smaller loan + lower payment + no PMI at 20%. Every extra $10K down reduces your monthly payment by ~$60.
๐
Interest Rates
At 6.29%, every $10K borrowed adds ~$62/month. Rate differences directly shrink or expand your buying power by tens of thousands.
๐
Location & Local Costs
Property taxes and insurance vary widely. A $400K home in Texas can cost $400+/month more than the same home in Nevada.
๐ฏ
Credit Score
Going from 680 to 760 can lower your rate 0.25%โ0.50% โ that's worth tens of thousands over the life of the loan.
FAQ
Affordability Calculator FAQ
How much house can I afford on a $75,000 salary?
As a rough guide, 3โ4ร your annual income: roughly $225,000โ$300,000. But your actual number depends on debts, down payment, interest rate, and local taxes. Use the calculator above with your real numbers for a personalized answer.
Does this include property taxes and insurance?
Yes โ enter monthly property tax and insurance amounts directly into the calculator. Budget 1.5%โ2.5% of the home's value annually for taxes and insurance combined as a starting estimate if you don't know your local rates.
What if I have student loan debt?
Enter your monthly student loan payment in the "Monthly non-housing debt payments" field. Even $300/month in student loans can reduce your buying power by $50,000+. FHA also has specific rules for student loans in deferment โ ask your lender.
Should I spend the maximum I'm approved for?
Generally no. Lenders approve based on what you can pay, not what you should pay. Keep housing below 25%โ28% of gross income when possible. Leave room for maintenance (1โ2% of home value/year), savings, and unexpected costs.
What's the difference between front-end and back-end DTI?
Front-end DTI = housing payment รท gross income (lenders typically cap at 28%). Back-end DTI = all monthly debts including housing รท gross income (usually capped at 36โ43%). Both limits are configurable in the calculator's qualification rules section.
Where can I get official guidance on mortgage affordability?
The Consumer Financial Protection Bureau (CFPB)
offers free tools and guidance on mortgage qualification, DTI limits, and what lenders look for.
HUD.gov
also provides resources for first-time homebuyers on budgeting and loan options.
