How Much House Can You Afford? A Practical Guide to Total Housing Costs

Start With Total Housing Cost, Not Just Mortgage

Most buyers begin with one question: "What mortgage payment can I handle?"

That’s a good start, but it’s not enough.

A safer question is: "What is my full monthly housing cost, and will it still feel manageable after I move in?"

Your real monthly number usually includes:

• Principal + interest (mortgage)
• Property taxes
• Homeowners insurance
• HOA/condo fees (if applicable)
• Maintenance and repair reserve
• Utilities (electric, gas, water, sewer, internet)
• Optional but common: flood insurance, landscaping, snow removal, pest control

Step 1: Set a Comfortable Monthly Target

Before calculators, define your comfort zone. Use your real take-home pay and current spending.

A practical way to set a target:

1. Start with monthly net income
2. Subtract fixed obligations (car, student loans, childcare, etc.)
3. Subtract living costs you want to preserve (food, savings, travel, retirement)
4. The remaining amount is your maximum housing budget

Then back off a little. Leave breathing room for surprises.

Step 2: Estimate Mortgage Payment First

Mortgage is still the largest line item, so model this first.

As you test scenarios, adjust:

• Purchase price
• Down payment
• Interest rate
• Loan term

Don’t stop at one payment estimate. Run multiple cases (best case, expected case, conservative case).

Step 3: Add Property Tax and Insurance

These are often underestimated, especially by first-time buyers.

Property Tax

Tax varies significantly by town and assessed value. Use the local tax rate and an updated assessed value estimate when possible.

For town-specific context, browse our Town Guides and Monthly Report by Town pages before finalizing your budget range.

Homeowners Insurance

Insurance depends on replacement cost, claim history, and location risk. Get real quotes early instead of using generic placeholders.

Step 4: Add Maintenance and Repair Reserve

Every home needs ongoing upkeep, even newer homes.

A common planning range is 1%-2% of home value per year, adjusted for age/condition.

Examples:

• $700,000 home -> roughly $583-$1,167/month reserve
• $1,000,000 home -> roughly $833-$1,667/month reserve

This is not "extra." It’s part of true ownership cost.

Step 5: Include Utilities and Ownership "Friction" Costs

These smaller items add up faster than most buyers expect.

Include realistic monthly estimates for:

• Electric + gas/oil/heat
• Water + sewer
• Internet
• Trash (if paid separately)
• Seasonal services (lawn/snow)

Also account for one-time move-in costs:

• Basic furnishing and setup
• Minor fixes and immediate upgrades
• Moving costs

Step 6: Check Your Cash Position (Not Just Monthly Payment)

Affordability is both a monthly and cash question.

Before buying, plan for:

• Down payment
• Closing costs
• Initial repair/furnishing budget
• Emergency reserve after closing (ideally 3-6 months of expenses)

If your cash is exhausted at closing, your risk is too high even if the monthly payment looks "okay."

Step 7: Stress-Test Before You Commit

Run a simple stress test before deciding your max price:

• What if rates are 0.5%-1.0% higher?
• What if taxes are reassessed upward?
• What if one major repair happens in year one?
• What if one income stream is interrupted for a few months?

If one stress case breaks the budget, lower the price target now, not after closing.

A Simple Affordability Framework You Can Use Today

Think in three tiers:

• Comfortable: You can save monthly and still live normally
• Stretch: You can make it work, but flexibility is limited
• Risky: Any surprise expense creates stress or debt

Aim for comfortable, not "maximum approval amount."

Final Thoughts

Buying power and affordability are not the same thing. The right purchase price is the one that supports your long-term goals, not just the one a lender might approve.
