Understanding Your Mortgage Affordability
Buying a home is one of the biggest financial decisions you'll ever make. Our mortgage calculator helps you understand exactly how much house you can afford based on your income, debts, and down payment. Unlike simple calculators that only show monthly payments, we provide a comprehensive analysis that considers all aspects of homeownership.
The mortgage approval process involves multiple factors beyond just your income. Lenders evaluate your debt-to-income ratio, credit score, employment history, and available assets. Understanding these factors before you start house hunting can save you time and help you set realistic expectations.
Key Factors That Determine Your Mortgage Affordability
- •Debt-to-Income Ratio (DTI): Most lenders prefer a DTI below 43%, though some may go up to 50% with compensating factors
- •Credit Score: Higher scores (740+) qualify for the best rates, potentially saving thousands over the loan term
- •Down Payment: 20% avoids PMI, but programs exist for as little as 3-5% down
- •Cash Reserves: Lenders like to see 2-6 months of mortgage payments in savings
Our calculator uses the same guidelines that mortgage lenders use, giving you an accurate picture of what you can qualify for. We also provide a more conservative estimate based on financial best practices, helping you avoid becoming "house poor" – a situation where your housing costs leave little room for other expenses and savings.

Calculation Method
Understanding Interest Rates
Mortgage interest rates significantly impact your buying power. A difference of just 1% can mean tens of thousands of dollars over the life of your loan.
Rate Impact Example:
On a $300,000 loan:
- • 6.5% rate = $1,896/month
- • 7.5% rate = $2,097/month
- • Difference: $201/month or $72,360 over 30 years
Factors affecting your rate include credit score, down payment size, loan term, and current market conditions. Even small improvements to your credit score can lead to significant savings.
Hidden Costs of Homeownership
Your mortgage payment is just one part of homeownership costs. Budget for these additional expenses:
- 💰Property Taxes: Typically 1-2% of home value annually
- 🏠Homeowners Insurance: $1,000-3,000+ per year
- 🔧Maintenance: Budget 1-3% of home value annually
- 🏘️HOA Fees: Can range from $100-1000+ monthly
Complete Guide to Getting a Mortgage
Types of Mortgages Explained
Conventional Loans
The most common type of mortgage, not backed by government agencies. Requires at least 3% down for first-time buyers, 5% for repeat buyers. Best for borrowers with good credit (620+) and stable income.
FHA Loans
Government-backed loans with more flexible requirements. Allow down payments as low as 3.5% with a 580+ credit score. Popular with first-time buyers but require mortgage insurance for the life of the loan.
VA Loans
Available to eligible veterans and service members. Offer 0% down payment options and no PMI requirement. Often have the best rates available but require a VA funding fee.
USDA Loans
For properties in eligible rural and suburban areas. Offer 0% down payment options for qualified buyers. Income limits apply based on area median income.
The Mortgage Application Process
Pre-qualification (1-2 days)

Pre-approval (3-10 days)
Detailed review including credit check and income verification. Results in a conditional commitment for a specific loan amount.
House Hunting and Offer
Shop within your pre-approved range. Make offers with your pre-approval letter to strengthen your position.
Formal Application

Processing and Underwriting (30-45 days)

Common Mistakes to Avoid
- ⚠️Making major purchases before closing: Don't buy a car, furniture, or open new credit accounts during the mortgage process.
- ⚠️Changing jobs during the process: Employment changes can derail your approval. Wait until after closing.
- ⚠️Forgetting about closing costs: Budget 2-5% of the purchase price for closing costs and prepaid items.
- ⚠️Not shopping around: Compare offers from multiple lenders - even a 0.25% difference adds up over 30 years.
- ⚠️Maxing out your budget: Leave room for maintenance, emergencies, and lifestyle expenses.
