How Much Is My Home Worth? And How Much House Can I Afford?

Buying or selling a home usually starts with two important questions: How much is my home worth? and How much house can I afford?

They sound similar, but they solve different problems. A home’s estimated market value helps sellers understand what buyers might pay. Affordability helps buyers decide whether the monthly costs fit their income and financial commitments.

Getting both estimates right can prevent expensive mistakes. An online home valuation may provide a useful starting point, but it is not the same as an appraisal. Similarly, a mortgage lender may approve a loan amount that feels uncomfortable once everyday expenses are included.

Here is how to approach both questions using practical examples and current US housing information.

How Much Is My Home Worth?

A home’s market value is generally the price a willing buyer might pay under normal market conditions. It depends on more than the property’s size or original purchase price.

Important factors include:

• Location and neighbourhood demand
• Recent sales of similar nearby properties
• Property size, layout and condition
• Number of bedrooms and bathrooms
• Renovations and maintenance
• Local inventory and competing listings

For example, two houses with similar floor areas can have different values if one has a renovated kitchen, a newer roof or a more desirable location.

1. Compare Recent Sales in Your Area

One practical way to estimate a property’s value is to examine recently sold homes that are similar to yours. Real estate professionals often refer to these as comparable sales, or “comps.”

Look for properties with similar:

• Location and neighbourhood
• Square footage
• Property type and age
• Bedroom and bathroom count
• Condition and features

For instance, imagine three comparable homes recently sold for $385,000, $400,000 and $415,000.

Their simple average is:

($385,000 + $400,000 + $415,000) ÷ 3 = $400,000

This gives you a starting estimate, not a guaranteed selling price. Differences in property condition, lot size and sale timing can justify adjustments.

2. Use Online Home Value Estimates Carefully

Online property valuation tools can provide a quick estimate using available property records, recent sales and market information.

However, automated estimates may not know about a recently renovated bathroom, foundation damage, a new roof or other details that affect a property’s condition.

Use more than one estimate where possible, compare the results with recent local sales, and treat any online figure as a guide rather than a formal valuation.

3. Consider a Professional Appraisal

A professional appraisal provides a more detailed assessment of a property’s value. An appraiser considers the property’s characteristics and relevant market evidence.

An appraisal may be required by a mortgage lender during a purchase or refinance. Sellers can also consider professional advice when preparing a listing price.

How Much House Can I Afford?

The answer depends on your income, existing debt, savings, credit profile, mortgage rate and other ownership costs.

A lender’s approval amount is not necessarily the amount you should spend. The Consumer Financial Protection Bureau (CFPB) recommends considering your own budget and financial priorities rather than relying only on the amount a lender is willing to provide. It also helps to understand how lenders decide your loan eligibility.

Your total housing budget should account for:

• Mortgage principal and interest
• Property taxes
• Homeowners insurance
• Mortgage insurance, if applicable
• HOA fees, where relevant
• Maintenance and repairs

A Practical Home Affordability Calculation

Let’s consider a hypothetical US home purchase.

Assumptions:

Item	Amount
Home purchase price	$400,000
Down payment	20% ($80,000)
Mortgage loan	$320,000
Loan term	30 years
Illustrative interest rate	7.24% fixed

Freddie Mac reported an average 30-year fixed mortgage rate of 7.24% on October 29, 2026. This is a market benchmark, not a rate every borrower will receive.

At 7.24%, a $320,000 mortgage over 30 years produces an estimated monthly principal-and-interest payment of approximately $2,180.

For a broader monthly budget, assume:

Monthly expense	Illustrative amount
Principal and interest	$2,180
Property taxes	$300
Homeowners insurance	$100
Total before other costs	$2,580

These tax and insurance amounts are assumptions for the example, not national averages. Actual costs depend on the property and location. Maintenance, HOA fees and other expenses could increase the total.

The calculation also shows why looking only at the mortgage payment can give buyers an incomplete picture. For a salary-based example, see how much house you can afford on a $75,000 salary.

Do Not Forget the Down Payment and Closing Costs

The down payment is not the only cash needed to purchase a home.

The CFPB says closing costs typically range from 2% to 5% of the purchase price, excluding the down payment.

For a $400,000 home:

• 2% closing costs = $8,000
• 5% closing costs = $20,000
• 20% down payment = $80,000

That means the illustrative upfront cash requirement could be approximately $88,000 to $100,000, before moving costs, furnishings, repairs or an emergency reserve.

A down payment below 20% may also mean paying for private mortgage insurance on many conventional loans, depending on the loan terms. Keep a separate emergency fund rather than spending every available dollar on the purchase.

How Do Mortgage Rates Affect Affordability?

Interest rates can make a noticeable difference to monthly payments. Your credit score and loan details can also affect the rate a lender offers you.

For example, the same $320,000 mortgage over 30 years would have an approximate principal-and-interest payment of:

Interest rate	Monthly payment
6.50%	$2,023
7.24%	$2,180
7.75%	$2,292

These are illustrative calculations using fixed rates and excluding taxes, insurance and fees.

At 7.75%, the monthly payment is about $269 higher than at 6.50%. Over a long repayment period, differences in borrowing costs can add up substantially.

This is why buyers should compare loan estimates and avoid assuming that a future rate reduction will necessarily happen.

What Is Happening in the US Housing Market?

The Federal Housing Finance Agency (FHFA) reported that US house prices increased 2.6% between July 2025 and July 2026, based on its seasonally adjusted House Price Index.

That national figure does not describe every local market. Prices can rise in one city while remaining flat or falling in another.

Before estimating your home’s value or deciding how much to spend, check recent sales and local market conditions rather than relying only on national headlines.

Common Mistakes to Avoid

Relying on one online estimate: Automated tools cannot always account for property condition or recent improvements.

Ignoring total ownership costs: Taxes, insurance, maintenance and HOA fees can make a seemingly affordable mortgage difficult to manage.

Using the lender’s maximum approval as your budget: A larger loan may leave less room for savings, emergencies and other financial goals.

Spending all available savings on the purchase: Keep money aside for moving, repairs and unexpected expenses.

Assuming home prices always rise: Property values can decline, and selling costs may reduce the money you receive.

Final Thoughts

Knowing how much your home is worth and how much house you can afford requires two separate calculations. Sellers should compare their property with recent local sales and consider its actual condition. Buyers should look beyond mortgage approval and calculate the full cost of ownership.

A realistic budget, reliable property comparisons and a financial cushion can help make a home purchase more manageable. The goal is not simply to buy the most expensive home a lender will approve, but to choose a property that fits your long-term financial plans.
