Buying a home is one of the biggest financial decisions you can make. Before you start touring properties or applying for a mortgage, it is important to understand one basic question:
How much house can you actually afford?
The answer is not simply the largest mortgage a lender is willing to approve. Your affordable home price should leave enough room in your budget for everyday expenses, savings, emergencies, retirement, repairs, insurance, taxes, and other financial goals.
The Consumer Financial Protection Bureau (CFPB) specifically recommends focusing on what you can comfortably afford rather than simply how much a lender says you qualify for.
This guide explains how to estimate your affordable home price, what lenders consider, how much income you may need, and common mistakes to avoid in 2026.
What Determines How Much House You Can Afford?
Several factors affect your home-buying budget:
- Your gross monthly income
- Existing monthly debt
- Credit score and credit history
- Down payment
- Mortgage interest rate
- Loan term
- Property taxes
- Homeowners insurance
- Mortgage insurance
- HOA fees
- Maintenance and repair costs
- Your emergency savings
- Other financial goals
The CFPB notes that your affordable home price depends on factors including your monthly budget, down payment, loan type, interest rate and terms, and ongoing property costs.
That means two people earning the same salary may have very different home-buying budgets.
A Simple Rule of Thumb for Home Affordability
One traditional guideline is the 28% rule.
Under this approach, your total monthly housing payment should generally be around 28% or less of your gross monthly income.
For example, if your household earns:
$8,000 per month before taxes
Then:
$8,000 × 28% = $2,240
That gives you a rough target of about $2,240 per month for your total housing payment.
However, this is only a starting point. The CFPB emphasizes that affordability should be based on your complete financial situation rather than a single percentage.
Don’t Forget Your Total Monthly Housing Payment
One of the biggest mistakes prospective buyers make is looking only at the mortgage principal and interest.
Your real housing cost can include:
| Cost | What It Covers |
|---|---|
| Principal | Amount borrowed toward the home |
| Interest | Cost of borrowing the money |
| Property taxes | Local taxes on the property |
| Homeowners insurance | Insurance protecting the property |
| Mortgage insurance | May apply with certain loan structures |
| HOA fees | Required fees for some communities |
| Maintenance | Repairs and ongoing upkeep |
| Flood/supplementary insurance | May apply depending on location |
The CFPB recommends including property taxes, homeowners insurance, mortgage insurance, HOA fees and other ownership costs when determining what you can comfortably afford.
A house that looks affordable based on principal and interest alone could become expensive once these additional costs are included.
How Your Income Affects Home Affordability
Your income is one of the most important factors in determining your mortgage budget.
Suppose your household earns $100,000 per year.
Your gross monthly income is approximately:
$100,000 ÷ 12 = $8,333
Using a 28% housing guideline:
$8,333 × 0.28 ≈ $2,333
This does not mean you automatically qualify for a mortgage payment of $2,333. Your lender will also consider your debts, credit profile, assets and other information.
And importantly, a lender’s maximum approval isn’t necessarily the same as your personal comfort level.
Understand Your Debt-to-Income Ratio
Another major factor is your debt-to-income ratio (DTI).
DTI compares your monthly debt obligations with your gross monthly income.
The basic calculation is:
DTI = Total Monthly Debt ÷ Gross Monthly Income × 100
For example, suppose you earn $8,000 per month and have:
- Car payment: $500
- Student loan: $300
- Credit card payments: $200
- Proposed housing payment: $2,000
Your total monthly debt would be:
$500 + $300 + $200 + $2,000 = $3,000
Your DTI would be:
$3,000 ÷ $8,000 = 37.5%
Lenders use DTI as one measure of your ability to manage debt payments. Different loan programs and lenders can have different limits.
For example, Fannie Mae’s current guidelines allow qualifying conventional borrowers to have DTI ratios as high as 50% in certain automated underwriting cases, while manually underwritten loans generally have lower limits.
But just because you can qualify at a particular DTI doesn’t mean you should build your personal budget around the maximum.
How Much Should You Put Down?
Your down payment can significantly affect your mortgage.
A larger down payment generally means:
- A smaller mortgage
- Lower monthly principal and interest
- Potentially lower mortgage insurance costs
- Lower loan-to-value ratio
- Less interest paid over the life of the loan
A 20% down payment is not universally required. Fannie Mae notes that some conventional loans can allow down payments as low as 3%, depending on eligibility.
However, putting less than 20% down can result in mortgage insurance on many conventional loans.
The CFPB also recommends keeping an emergency cushion instead of putting every dollar of savings into the down payment. It suggests considering at least three to six months of expenses as an emergency cushion.
Don’t Empty Your Savings to Buy a Bigger House
A common mistake is using almost all available savings for the down payment.
Imagine you have:
$80,000 in savings
You might technically be able to put most of it toward your home purchase. But doing so could leave you with little money for:
- Closing costs
- Moving expenses
- Furniture
- Repairs
- Emergency expenses
- Job loss
- Medical expenses
- Other unexpected costs
The CFPB recommends accounting for closing costs, moving expenses, renovations and an emergency cushion before deciding how much cash to put toward the purchase.
A slightly cheaper house with healthy savings may be easier to manage than a more expensive house that leaves you financially stretched.
How Interest Rates Affect How Much House You Can Afford
Mortgage rates have a major effect on affordability.
The same loan amount can produce significantly different monthly payments at different interest rates.
For example, consider a hypothetical $400,000 mortgage:
| Interest Rate | Loan Term | Approx. Principal & Interest |
|---|---|---|
| 5% | 30 years | ~$2,147/month |
| 6% | 30 years | ~$2,398/month |
| 7% | 30 years | ~$2,661/month |
| 8% | 30 years | ~$2,935/month |
These figures are illustrative and exclude taxes, insurance, mortgage insurance and other costs.
This is why you should not calculate affordability based on the home price alone. Your mortgage rate can substantially change the monthly payment.
The CFPB recommends using a realistic interest-rate assumption when estimating your affordable home price and revisiting the calculation as you obtain more information.
Example: How to Calculate an Affordable Home Price
Let’s say you have:
- Annual household income: $96,000
- Gross monthly income: $8,000
- Existing monthly debt: $700
- Down payment: $50,000
- Emergency savings: Separate
- Target housing budget: $2,000 per month
You could start by determining how much of the $2,000 would actually be available for principal and interest.
Suppose you estimate:
- Property taxes: $300/month
- Homeowners insurance: $150/month
- Mortgage insurance/other costs: $100/month
That leaves approximately:
$2,000 − $300 − $150 − $100 = $1,450
So your estimated principal-and-interest budget would be around $1,450 per month.
You could then use a mortgage calculator to estimate the loan amount that fits that payment.
Finally, add your available down payment to estimate a potential home price.
This is only an illustration. Your actual affordability will depend on your interest rate, loan program, taxes, insurance, credit profile and other costs.
A Better Way to Think About Affordability
Instead of asking:
“What is the most expensive house I can qualify for?”
Ask:
“What monthly payment can I comfortably afford while still reaching my other financial goals?”
This approach is more useful because buying a home does not eliminate your other expenses.
You may still need money for:
- Retirement contributions
- Emergency savings
- Transportation
- Food
- Healthcare
- Childcare
- Education
- Travel
- Debt repayment
- Home maintenance
- Other investments
The CFPB specifically recommends considering your broader financial priorities rather than simply maximizing your mortgage approval.
Don’t Forget Closing Costs
Your down payment isn’t the only cash you’ll need.
Closing costs can include:
- Loan fees
- Appraisal
- Title-related costs
- Government charges
- Prepaid taxes
- Insurance
- Other transaction expenses
The CFPB says closing costs typically range from about 2% to 5% of the home purchase price, excluding the down payment, although actual costs vary by loan, lender, location and transaction.
For a $400,000 home, 2% to 5% would represent roughly:
$8,000 to $20,000
That can make a significant difference to your cash requirements.
Consider Maintenance and Repairs
Renters generally call a landlord when something major breaks.
Homeowners are responsible for their property’s maintenance.
Potential expenses include:
- Roof repairs
- HVAC replacement
- Plumbing
- Appliances
- Electrical work
- Landscaping
- Painting
- Pest control
- Water damage
- General maintenance
The CFPB recommends considering repair and maintenance expenses when evaluating the financial commitment of homeownership.
Don’t assume your monthly mortgage payment represents the entire cost of owning a home.
What If You Can’t Afford the Home You Want?
If your preferred home is outside your comfortable budget, you have several options.
You could:
- Increase your down payment.
- Pay down existing debt.
- Improve your credit profile before applying.
- Look at less expensive properties.
- Consider a different location.
- Wait and increase your savings.
- Compare different mortgage programs.
- Increase household income.
- Reduce other monthly expenses.
- Reassess your target monthly payment.
The goal isn’t necessarily to buy the biggest home possible. The goal is to purchase a home without putting unnecessary pressure on your overall finances.
Home Affordability Checklist for 2026
Before making an offer, consider whether you can comfortably handle:
- Monthly mortgage payment
- Property taxes
- Homeowners insurance
- Mortgage insurance, if applicable
- HOA fees, if applicable
- Utilities
- Maintenance and repairs
- Closing costs
- Down payment
- Emergency savings
- Existing debt payments
- Retirement contributions
- Other financial goals
Also check whether your income is stable and whether you expect any major financial changes in the near future.
The CFPB lists steady income, manageable debt, savings for a down payment and the ability to handle taxes, insurance and other ownership expenses among the factors prospective buyers should consider.
Final Thoughts
So, how much house can you afford?
There isn’t one universal number.
Your affordable home price depends on your income, debts, down payment, credit profile, interest rate, loan term, taxes, insurance, mortgage insurance, maintenance costs and financial goals.
A lender may approve you for more than you personally want to spend. That’s why it is important to build your own budget before relying on a lender’s maximum loan amount.
Start with a comfortable monthly housing payment, account for all homeownership costs, protect your emergency savings, and then work backward to determine a realistic home price.
The right home is not necessarily the most expensive one you can qualify for. It is one that fits your overall financial life.
