The Answer: $350,000–$420,000 on a $100k Salary

The quick answer

On a $100,000 gross salary with 2026 mortgage rates averaging 6.8%, no other debts, and a 10% down payment, you can afford a home priced between $350,000 and $420,000. The range depends on your property taxes, insurance, and which affordability rule your lender uses. With existing debts (car payment, student loans), the ceiling drops — every $500/month in other debts reduces your affordable home price by roughly $65,000–$70,000.

Key takeaways
  • The 28/36 rule limits your housing payment to 28% of gross income ($2,333/month on $100k) and total debts to 36% ($3,000/month).
  • At 6.8% on a 30-year mortgage with 10% down, a $400,000 home costs approximately $2,348/month in principal and interest alone — add taxes and insurance for the full picture.
  • FHA loans allow higher debt-to-income ratios (up to 50% in some cases), which can push the ceiling higher — but with a cost: mandatory mortgage insurance. See our FHA Loan Calculator.
  • Property taxes vary from 0.31% (Hawaii) to 2.23% (New Jersey) of home value — a $400,000 home costs $1,240/year in Hawaii versus $8,920/year in New Jersey, directly affecting what you can afford.
Max home price = (Monthly income × 0.28 − taxes − insurance) ÷ mortgage rate factor × (1 + down payment %)
Variables
Monthly income — gross (pre-tax) monthly salary: $100,000 ÷ 12 = $8,333
28% housing ratio — max housing payment: $8,333 × 0.28 = $2,333
Mortgage rate factor — monthly P&I per $1,000 borrowed at 6.8% / 30yr = $6.51
Down payment — reduces the loan amount; 10% down means financing 90%
Example: $2,333 − $400 (taxes/insurance estimate) = $1,933 for P&I → $1,933 ÷ $6.51 × 1,000 = $296,928 loan → ÷ 0.90 = ~$329,920 home. With lower taxes or 20% down, the number climbs toward $420,000.

Home Affordability by Salary: $60k to $200k

The math scales predictably with income. Here's what each salary level can afford under the 28/36 rule with 2026 rates, assuming 10% down, no other debts, and average U.S. property taxes (1.1%):

Gross salaryMax monthly housing (28%)P&I budget*Approximate home priceMonthly P&I payment
$60,000$1,400$1,050$210,000–$250,000$1,490
$75,000$1,750$1,350$270,000–$310,000$1,862
$80,000$1,867$1,450$290,000–$335,000$2,009
$100,000$2,333$1,850$350,000–$420,000$2,497
$120,000$2,800$2,250$430,000–$510,000$3,057
$150,000$3,500$2,900$550,000–$640,000$3,810
$200,000$4,667$3,950$740,000–$860,000$5,143
*P&I budget = max housing payment minus estimated property tax and insurance. Home price ranges reflect variation in local property taxes (0.5%–2.0%) and insurance. All figures assume 6.8% rate, 30-year fixed, 10% down, no PMI above 20% equity. Freddie Mac PMMS average rate as of June 2026.

Notice how the range widens at higher incomes: a $200,000 earner's ceiling varies by $120,000 depending on whether they're in a low-tax state like Hawaii or a high-tax state like New Jersey. Location matters as much as salary.

What lenders approve ≠ what you can comfortably afford

Lenders will approve up to the 28/36 limits — and FHA lenders may go higher. But spending 28% of gross income on housing often means 35–40% of take-home pay, leaving less for retirement savings, emergencies, and discretionary spending. Many financial planners recommend keeping housing at 25% of take-home pay instead. Use our take-home pay guide to see what your salary actually deposits each month, then work backward from that number.

What Moves the Number: Down Payment, Rates, and Debt

Down Payment Impact

The down payment affects affordability in two ways: it reduces your loan (lowering the monthly payment) and — at 20% or more — eliminates PMI, which typically costs 0.5–1.5% of the loan annually. On a $100k salary:

Down paymentHome price affordableLoan amountMonthly P&IPMI cost/month
3% (FHA minimum)$310,000$300,700$1,959$130–$260
5%$340,000$323,000$2,105$135–$270
10%$385,000$346,500$2,258$144–$290
20% (no PMI)$420,000$336,000$2,189$0
Assumes $100,000 salary, 6.8% rate, 30-year term, 1.1% property tax, $1,200/year insurance. PMI estimated at 0.5–1.0% of loan. Higher down payments unlock higher purchase prices because the monthly payment stays under the 28% threshold.

Interest Rate Sensitivity

Every 1% change in mortgage rates shifts affordable home prices by roughly 10–12%. On a $100k salary with 10% down:

Mortgage rateApproximate max home priceMonthly P&I on $360k loan
5.5%$430,000$2,044
6.0%$410,000$2,158
6.8% (current avg)$385,000$2,348
7.5%$355,000$2,516
8.0%$335,000$2,641
Same assumptions: $100k salary, 10% down, 28% front-end ratio, 1.1% property tax. Rate source: Freddie Mac PMMS historical data.

How Existing Debt Shrinks Your Budget

The 36% back-end ratio caps your total monthly debt at $3,000 on a $100k salary. Every dollar going to car loans, student loans, or credit card minimums reduces what's left for housing:

Monthly debt paymentsHousing budget remainingApproximate max home price
$0$2,333 (full 28%)$385,000
$300 (car payment)$2,333*$385,000
$500 (car + student loan)$2,333*$385,000
$700 (car + student + CC)$2,300$375,000
$1,000$2,000$320,000
$1,500$1,500$230,000
*When total debts are under 36% of income ($3,000/month), the 28% front-end ratio is the binding constraint, so the housing limit doesn't change. Once debts push total obligations past 36%, the back-end ratio becomes the limiter.
Pay off a car loan before applying — it's a powerful move

Eliminating a $400/month car payment doesn't just free up $400 for housing. Because lenders look at the back-end ratio, removing that $400 can increase your home buying power by $50,000–$65,000. If you're within a year of paying off a car, it may be worth waiting to buy until it's clear.
