How Much House Can I Afford? (2026 Guide)

“How much house can I afford?” is the first question every buyer asks — and the one most buyers answer wrong. The classic mistake is treating the lender’s maximum as a target. A lender’s approval tells you the most you can borrow under their formulas. It says nothing about whether the payment leaves room for groceries, savings, childcare, or the water heater that will die in year two.

This guide gives you both: the lender’s number (28/36 rule and debt-to-income ratio) and your number (your actual budget). Work the math with your figures and you will know your price range, monthly payment, and cash needed at closing.

The Short Answer: What “Afford” Really Means

Two different answers exist, and confusing them is how people end up house poor:

• What you qualify for: the maximum a lender will approve, from your income, debts, credit, and down payment — typically anchored to the 28/36 rule below.
• What you can comfortably afford: the price whose total monthly cost (mortgage, taxes, insurance, PMI, HOA, maintenance) fits your take-home pay while leaving room for savings and real life.

These numbers are often far apart. Smart buyers shop to the lower one. Gut-check: if the total monthly cost would top a third of take-home pay or force you to stop saving, it is too much house — approval or not.

Quick ballpark by salary, using the 28% guideline at an illustrative 6.75% 30-year rate, 20% down, ~1.1%/yr property tax, ~$1,800/yr insurance, and no other debts (debts shrink these — see the worked example):

Annual income	Max housing (28%)	Illustrative max price*
$50,000	$1,167/mo	~$167,000
$75,000	$1,750/mo	~$262,000
$100,000	$2,333/mo	~$358,000
$125,000	$2,917/mo	~$453,000
$150,000	$3,500/mo	~$549,000
$200,000	$4,667/mo	~$740,000

*Illustrative only, as of 2026. Real affordability depends on debts, credit, exact rate, local taxes/insurance, and lender guidelines, which vary. Use the worksheet below for your personal number.

The 28/36 Rule, Explained With Real Math

The 28/36 rule is the guideline most lenders start from. Both parts use gross (pre-tax) monthly income:

• 28% — front-end ratio: total housing costs (PITI plus HOA/PMI where they apply) at or under 28% of gross monthly income.
• 36% — back-end ratio: all monthly debts — housing plus car, student loans, card minimums, personal loans, support payments — at or under 36%.

It is a guideline, not a law — conventional loans often allow 45% back-end ratios, and FHA/VA loans may stretch further with strengths like excellent credit or big cash reserves.

The classic $6,000/month example: max housing = $6,000 × 0.28 = $1,680; max total debt = $6,000 × 0.36 = $2,160. With $500/month in car and student loan payments, the back-end room for housing is $2,160 − $500 = $1,660 — which binds, beating the $1,680 front-end figure. Whichever limit is lower wins. That is the entire game, and the next section plays it out fully.

Front-End vs Back-End DTI: A Full $75,000 Worked Example

A hypothetical household earns $75,000/year ($6,250/month). Monthly debts: car $380, student loans $320, card minimums $60 — $760 total.

Step 1 — front-end limit: $6,250 × 0.28 = $1,750/month max PITI.
Step 2 — back-end limit: ($6,250 × 0.36) − $760 = $2,250 − $760 = $1,490/month max PITI.
Step 3 — take the lower: $1,490 binds. That is the lender-style housing budget.

Step 4 — convert to a home price (illustrative 6.75%, 30-yr, 10% down, ~1.1%/yr tax, $150/mo insurance, ~0.5%/yr PMI): $1,490/month supports about a $188,000 home (~$18,800 down, ~$169,200 loan). Check: P&I ≈ $1,097 + tax ≈ $172 + insurance $150 + PMI ≈ $71 = $1,490. ✓

With zero debts, the same household gets the full $1,750 budget — about a $224,000 home. That $760/month of debt costs roughly $36,000 in buying power. Rerun this math with your own debts on our loan eligibility calculator.

PITI: The Four Costs Inside Every Mortgage Payment

Buyers who budget on principal and interest alone get blindsided. The 28% rule counts PITI, usually collected monthly into escrow:

Component	What it is	$350K home, 10% down, 6.75%, 30-yr
Principal + Interest	Loan paydown + lender’s charge ($315,000 loan)	$2,043/mo
Taxes	Property tax (~1.1%/yr in this example)	$321/mo
Insurance	Homeowners insurance (lenders require it)	$150/mo
+ PMI	Mortgage insurance when down payment < 20%	$131/mo
Total monthly housing cost		$2,645/mo

P&I ($2,043) is only ~77% of the true $2,645 cost. Taxes and insurance swing wildly by location — always price PITI with local figures, and stack HOA dues on top where they apply.

Down Payment: 5% vs 10% vs 20% on a $350,000 Home

Down payment hits affordability three ways: smaller loan, PMI or no PMI, and cash needed at closing. Same $350,000 home, 6.75%, 30 years:

	5% down	10% down	20% down
Cash down	$17,500	$35,000	$70,000
Loan amount	$332,500	$315,000	$280,000
P&I	$2,157/mo	$2,043/mo	$1,816/mo
PMI (illustrative)	$166/mo	$131/mo	$0
Tax + insurance	$471/mo	$471/mo	$471/mo
Total monthly	$2,794/mo	$2,645/mo	$2,287/mo

From 5% to 20% down costs $52,500 more cash but saves ~$507/month and kills PMI. PMI typically runs ~0.3%–1.0% of the loan per year; on conventional loans you can usually request cancellation at 20% equity, and it generally drops automatically at 78% loan-to-value.

Waiting years to save 20% while prices climb is not automatically smarter — low-down-payment paths (3–5% conventional, 3.5% FHA, 0% VA/USDA for eligible buyers) exist for a reason. Model your own scenarios on our EMI calculator.

How Interest Rates Move Your Buying Power

Rates are affordability’s silent lever: one percentage point moves P&I by roughly $200 per $300,000 borrowed on a 30-year loan.

30-yr fixed rate	P&I on $300,000	Loan a $1,896/mo payment buys
6.0%	$1,799	~$316,000
6.5%	$1,896	~$300,000
7.0%	$1,996	~$285,000
7.5%	$2,098	~$271,000
8.0%	$2,201	~$258,000

The same $1,896 buys ~$316,000 of house at 6% but only ~$258,000 at 8%. Two takeaways: your credit score is a rate lever (see how to improve your credit score before applying), and do not try to time rates — buy when the payment fits; refinancing later is always an option if rates fall.

The Costs Nobody Warns You About

The mortgage payment is the headline; homeownership has a long tail. Budget these before setting your price range:

• Closing costs — typically 2–5% of the price. Lender fees, title insurance, appraisal, prepaid taxes/insurance, attorney fees. On $350,000: roughly $7,000–$17,500 cash at closing, on top of the down payment.
• PMI/MIP. Under 20% down on conventional: ~0.3%–1.0% of the loan per year. FHA’s MIP adds an upfront premium plus an annual premium that usually lasts the loan’s life with a small down payment.
• Maintenance — ~1% of value per year. On $350,000, about $3,500/year (~$290/month) for roof, HVAC, plumbing, appliances. Older homes run higher.
• HOA dues. Often hundreds monthly, plus surprise special assessments. Lenders count HOA in your housing ratio.
• Bigger utility and service bills. Houses cost more to heat, cool, and water than apartments — plus lawn care, pest control, and the like.
• Moving and furnishing. Movers, utility deposits, and first-month fix-ups routinely run thousands more than buyers expect.
• Your emergency fund. Keep 3–6 months of expenses intact after closing. Draining every dollar for the down payment turns the first big repair into credit card debt.

All in, a “$350,000 home” can easily demand $15,000–$30,000 beyond the sticker price in first-year cash. This is why the comfortable budget matters more than the lender’s maximum.

Pre-Approval vs Pre-Qualification

Similar names, very different weight:

	Pre-qualification	Pre-approval
Based on	Self-reported numbers	Verified docs: pay stubs, W-2s, tax returns, bank statements
Credit check	Usually none / soft pull	Usually a hard pull
Commitment	Rough estimate	Conditional commitment for a set amount (typically 60–90 days)
With sellers	Weak	Strong — your offer looks serious

Get pre-approved before shopping — but it is conditional, not guaranteed. Between pre-approval and closing: no new credit, no financed furniture, no job changes.

Your Step-by-Step Affordability Worksheet

Fifteen minutes with a calculator (or our EMI calculator):

1. Gross monthly income: annual salary ÷ 12, before taxes. Count a co-borrower only if they join the loan. Use stable, documentable income.
2. List monthly debts: car, student loans, card minimums, personal loans, support payments. Skip rent, utilities, groceries — lenders count debts, not living costs (you will count those in step 8).
3. Front-end limit: income × 0.28 = max PITI.
4. Back-end limit: (income × 0.36) − debts = max PITI after debts.
5. Take the lower of steps 3–4. That is your lender-style max monthly housing budget.
6. Subtract non-loan costs: property tax, insurance, PMI if under 20% down, HOA. The remainder is your principal-and-interest budget.
7. Convert P&I to a loan: at an illustrative 6.75%/30-yr, every $1,000 borrowed costs ~$6.49/month → loan ≈ (P&I budget ÷ 6.49) × 1,000. Use your actual quoted rate when you have one.
8. Add your down payment → estimated maximum home price.
9. Comfort check: test full PITI + PMI + HOA + ~1%/yr maintenance against take-home pay. Best method: live on the projected budget 2–3 months pre-purchase, banking the difference. If it hurts, lower the target.
10. Cash check: down payment + closing (2–5%) + moving money + 3–6 month emergency fund after closing. If the cash is not there, the price is not affordable yet — even if the monthly math works.

10 Common Mistakes That Wreck Affordability

1. Shopping at max pre-approval. The ceiling assumes flat lifestyle spending alongside 28%-of-gross housing. Leave a margin.
2. Budgeting P&I only. Taxes, insurance, PMI, and HOA can add 25–40% on top. Always budget full PITI.
3. Forgetting closing costs. Saving exactly the down payment leaves you thousands short at the table. Add 2–5%.
4. Draining savings to close. Zero reserves turns the first repair into debt. Keep 3–6 months of expenses.
5. New credit before closing. A financed sofa or car can shift your DTI and kill the approval mid-process.
6. Waiving inspection to win a bid. A few hundred dollars now versus tens of thousands in hidden foundation, roof, or mold damage.
7. Not comparing lenders. Get at least three quotes; small rate and fee differences compound over 30 years.
8. Misunderstanding ARMs. Know the worst-case adjusted payment before taking an introductory rate — be sure you could handle it.
9. Ignoring HOA costs. $250/month is $3,000/year, plus assessments that arrive without warning.
10. Buying on future income. Buy on today’s verified salary, not the raise you expect.

What to Do Next: Your Action Plan

1. Run your worksheet today (15 min). Write down both DTI limits and circle the lower — that is your ceiling, not your target.
2. Test-drive the payment for 2–3 months, banking the gap between current housing costs and projected PITI.
3. Attack the debts shrinking your back-end limit — each $100/month eliminated restores ~$100/month of budget.
4. Polish your credit — a better score can mean a better rate and more house per dollar. See how to improve your credit score before applying.
5. Price local taxes and insurance for your target neighborhoods — local numbers, not national averages.
6. Get pre-approved by 2–3 lenders when ~2–3 months out, and compare Loan Estimates line by line.
7. Shop 10–15% under your max. The margin covers surprises, protects savings, and keeps bidding wars from turning into panic overpays.

Frequently Asked Questions

How much house can I afford on a $75,000 salary?

With 20% down, no debts, and an illustrative 6.75% 30-year rate, about $262,000. With $760/month in existing debts and 10% down, the back-end DTI limit binds and it drops to about $188,000. Your debts, down payment, local taxes, and actual rate move this number — run the worksheet above with your figures.

What is the 28/36 rule?

A lender guideline: keep housing costs (PITI) at or under 28% of gross monthly income, and all monthly debts including housing at or under 36%. At $6,000/month, that is $1,680 for housing and $2,160 for total debts. It is a guideline, not a law — some loan programs allow higher ratios.

What does PITI stand for?

Principal, Interest, Taxes, Insurance — the four parts of a mortgage payment. Principal repays the loan, interest is the lender’s charge, property tax goes to local government, and homeowners insurance is lender-required. Taxes and insurance are usually escrowed monthly. PMI and HOA dues add on top.

What credit score do I need to buy a house?

No single minimum — it varies by loan type and lender. Conventional loans typically want around 620 or higher; FHA may go to 580 with 3.5% down; VA has no official floor but lenders set their own. A higher score usually means a better rate, which directly raises what you can afford.

How much down payment do I really need?

Typical minimums: 3–5% conventional, 3.5% FHA, 0% VA or USDA for eligible buyers. Twenty percent avoids PMI and cut about $507/month off a $350,000 home at 6.75% versus 5% down. But waiting years to save 20% while prices rise is not always the winning move.

Does pre-approval guarantee I will get the loan?

No — it is conditional. The loan can still fall through if your finances change before closing (new debt, job change, unsourced deposits), the appraisal comes in low, or the property has issues. Keep your finances frozen between pre-approval and closing day.

Can I afford a house if I have student loans or a car payment?

Usually yes — debts shrink your budget through the back-end DTI limit rather than disqualifying you. In our $75,000 example, $760/month in debts cut buying power from about $224,000 to about $188,000. Eliminating whole monthly payments before applying is the fastest way to raise your number.

How does the interest rate affect how much house I can afford?

Hugely. On a $300,000 30-year loan, each rate point moves P&I by about $200/month. A $1,896 payment buys about $316,000 of house at 6% but only about $258,000 at 8%. Your credit score drives your rate, making it one of your biggest affordability levers.

What is PMI and when does it go away?

Private mortgage insurance protects the lender when you put down under 20% on a conventional loan — typically 0.3%–1.0% of the loan per year, added monthly. You can usually request cancellation at 20% equity; it generally auto-terminates at 78% loan-to-value. FHA’s MIP works differently and often lasts the loan’s life.

Should I buy at the very top of my pre-approval amount?

Almost never. Pre-approval is a lender’s maximum from debt formulas — it ignores childcare, savings goals, and future repairs. Maxed-out buyers often go “house poor”: current on the mortgage but unable to save or absorb surprises. Shopping 10–15% below your max keeps ownership comfortable.

How much are closing costs?

Typically 2–5% of the price: lender fees, title insurance, appraisal, prepaid taxes and insurance, attorney fees. On $350,000, budget roughly $7,000–$17,500 cash at closing on top of the down payment. Compare Loan Estimates across lenders — the fees vary.

Can I buy a house if I am self-employed?

Yes, with more paperwork. Lenders typically want two years of tax returns, average your income, and use net (after write-offs) income — not gross revenue. Volatile income can reduce what they count. Talk to a lender 6–12 months before buying to learn exactly how your income will be calculated.
