Buying a home is a significant financial decision, and determining how much mortgage you can afford is a crucial first step in the process. Understanding affordability involves more than just your income; it also includes factors such as debt, credit score, down payment, and current interest rates. This guide will provide you with all the tools and knowledge you need to assess how much mortgage you can afford, ensuring a financially sound and stress-free home-buying experience.
1. Understanding Mortgage Affordability
What Does Mortgage Affordability Mean?
Mortgage affordability refers to the maximum amount you can comfortably borrow to purchase a home without straining your finances. This depends on factors like your monthly income, expenses, and overall financial health.
The 28/36 Rule
A common rule lenders use to assess affordability is the 28/36 rule:
- 28% of Your Gross Income for Housing
- Your monthly mortgage payment, including principal, interest, taxes, and insurance (PITI), should not exceed 28% of your gross monthly income.
- 36% for Total Debt Payments
- Your total monthly debt obligations, including the mortgage, car loans, credit cards, and student loans, should not exceed 36% of your gross income.
Why Understanding Affordability Matters
- Prevents financial strain.
- Ensures long-term financial stability.
- Helps you find homes within your budget, saving time and effort.
2. Key Factors Affecting Mortgage Affordability
Several variables impact how much mortgage you can afford. Understanding these factors will help you calculate your budget accurately.
Income
Your gross monthly income is the starting point for determining affordability. This includes wages, bonuses, freelance income, and any other regular earnings.
Debt-to-Income Ratio (DTI)
- How to Calculate DTI
- Divide your total monthly debt payments by your gross monthly income and multiply by 100 to get your DTI percentage.
- Why It Matters
- Lenders use your DTI to assess your ability to manage monthly payments. A lower DTI increases your chances of approval and better loan terms.
Credit Score
- Impact on Loan Terms
- A higher credit score qualifies you for lower interest rates, reducing monthly payments and overall loan costs.
- Improving Your Credit Score
- Pay bills on time, reduce credit card balances, and avoid opening new lines of credit before applying for a mortgage.
Down Payment
- Typical Down Payment Percentages
- A 20% down payment is ideal, but many lenders offer loans with as little as 3-5% down.
- Effect on Affordability
- A larger down payment reduces the loan amount, lowering monthly payments and avoiding private mortgage insurance (PMI).
Interest Rates
Interest rates significantly affect your monthly payment and overall loan cost. Compare rates from multiple lenders to secure the best deal.
Loan Term
- Common Terms
- 30-year fixed-rate mortgages have lower monthly payments but higher total interest costs.
- 15-year loans have higher monthly payments but save on interest over the loan’s term.
- Impact on Affordability
- Choose a term that balances monthly affordability with long-term savings.
Property Taxes and Insurance
Factor in local property taxes and homeowners insurance when calculating your monthly payment. These vary by location and property value.
3. How to Calculate How Much Mortgage You Can Afford
Step 1: Calculate Your Monthly Income
Add all sources of income to determine your gross monthly income. For example:
- Salary: $6,000/month
- Freelance Income: $1,000/month
- Total Gross Income: $7,000/month
Step 2: Estimate Monthly Debt Payments
List all monthly debt obligations, such as:
- Car loan: $400
- Student loan: $300
- Credit card payments: $200
- Total Debt: $900
Step 3: Use the 28/36 Rule
- Calculate 28% of Your Income
- $7,000 x 0.28 = $1,960 (maximum housing expense).
- Calculate 36% of Your Income
- $7,000 x 0.36 = $2,520 (maximum total debt, including mortgage).
- Determine Remaining Budget
- $2,520 – $900 (existing debt) = $1,620 (maximum mortgage payment).
Step 4: Factor in Additional Costs
Include property taxes, insurance, HOA fees, and PMI if applicable.
4. Tools and Resources for Calculating Affordability
Mortgage Calculators
Online mortgage calculators help estimate monthly payments by inputting loan amount, interest rate, term, and other variables.
Affordability Calculators
Affordability calculators consider income, debts, and down payment to give you a clear budget range.
Pre-Approval Process
Getting pre-approved by a lender provides an accurate picture of how much mortgage you can afford.
5. Tips for Maximizing Your Budget
Improve Your Credit Score
Higher credit scores lead to lower interest rates, which can save thousands over the loan term.
Save for a Larger Down Payment
A higher down payment reduces monthly payments and total loan costs. Aim for at least 20% to avoid PMI.
Shop Around for Lenders
Compare mortgage offers from multiple lenders to secure the best rates and terms.
Stick to Your Budget
Avoid stretching your finances by staying within your calculated affordability range.
6. Avoiding Common Mistakes
Underestimating Costs
Don’t overlook costs like maintenance, utilities, and repairs when budgeting for homeownership.
Overborrowing
Just because a lender approves you for a certain amount doesn’t mean you should borrow it all. Consider your comfort level with monthly payments.
Skipping Pre-Approval
Failing to get pre-approved can lead to wasted time looking at homes outside your budget.

Scenario 1: Dual-Income Household
- Combined Income: $9,000/month
- Total Debt: $1,500/month
- Down Payment: $50,000
- 28% Rule: $9,000 x 0.28 = $2,520 (housing budget).
- 36% Rule: $9,000 x 0.36 = $3,240 (total debt limit).
- Remaining Mortgage Budget: $3,240 – $1,500 = $1,740/month.
This household can afford a home with a monthly mortgage payment of $1,740, including taxes and insurance.
Scenario 2: Single-Income Household
- Income: $4,500/month
- Total Debt: $800/month
- Down Payment: $20,000
- 28% Rule: $4,500 x 0.28 = $1,260 (housing budget).
- 36% Rule: $4,500 x 0.36 = $1,620 (total debt limit).
- Remaining Mortgage Budget: $1,620 – $800 = $820/month.
This individual can afford a home with a monthly mortgage payment of $820, including taxes and insurance.
