If you earn $80K a year and want to know what mortgage you can afford, the answer is roughly $248,000–$295,000 at current rates - which buys a home in the $280,000–$315,000 range with a normal down payment. Here is the full math, including what changes if that $80K is two incomes instead of one.
The monthly math
$80,000 ÷ 12 = $6,666.67/month gross. The standard 28/36 rule:
- Front-end (28%): housing ≤ $6,666.67 × 0.28 = $1,866.67/month
- Back-end (36%): all debts ≤ $6,666.67 × 0.36 = $2,400/month
At 6.5% on a 30-year fixed loan, each $1,000 borrowed costs about $6.32/month in principal and interest:
- P&I only: $1,866.67 ÷ $6.32 × $1,000 ≈ $295,000 mortgage
- With taxes + insurance (~$300/month): real P&I budget $1,566.67 → ≈ $248,000 mortgage
Your realistic approval range: $248K–$295K.
What home price does that buy?
For a $300,000 home at 6.5%:
| Down payment | Loan amount | Monthly P&I | Notes | |---|---|---|---| | 3.5% (FHA) | $289,500 | ~$1,830 | Plus mortgage insurance for the life of the loan | | 10% down | $270,000 | ~$1,707 | PMI ~$155/mo until 20% equity | | 20% down | $240,000 | ~$1,517 | No PMI - cheapest long-term |
With 20% down ($60,000), a $300K home costs ~$1,517 P&I + ~$300 taxes/insurance = ~$1,817/month - just inside the $1,867 budget. That is why $280K–$315K is the sweet spot on $80K.

Debts shrink it fast
The back-end cap is $2,400/month total. How debts change your mortgage:
- No debts: full $1,867 housing → ~$248K–$295K mortgage
- $500/month debts: housing capped at $1,900 → front-end still binds → same range
- $800/month debts: housing capped at $1,600 → mortgage roughly $206K–$253K
- $1,200/month debts: housing capped at $1,200 → mortgage roughly $142K–$190K
A single $800/month car-plus-student-loan combo costs you roughly $40K–$90K of mortgage. Clearing debts before applying is the highest-leverage move at this income.
Combined income of $80K: two earners
An $80K household income from two earners gets the same DTI math - lenders add both gross incomes and both sets of debts. Three things to know:
- Both credit scores matter. The lender typically uses the lower middle score of the two borrowers for pricing. One weak score can cost you a rate tier.
- Both debts count. Two car payments hit the back-end ratio twice as hard.
- Job stability counts double. If one income is new, part-time or variable, the lender may discount it.
A single $80K earner with no debts will usually qualify slightly more cleanly than two $40K earners with two car loans - same income, different debt picture.
Paid biweekly? Your per-paycheck housing budget
$80,000 ÷ 26 paychecks = $3,076.92 gross per paycheck. The 28% housing budget in the same rhythm: $861.54 per paycheck for all housing costs. Twice a year a third paycheck lands in the same month - routing those two "bonus" paychecks toward principal is the classic biweekly payoff trick without a special program.
Should you borrow the max?
$1,867/month is the ceiling, not the target. On $80K gross (~$5,400/month take-home after federal tax and FICA, before state tax), a maxed-out payment leaves about $3,500 for everything else. Comfortable - but one job loss or major repair changes the picture fast. Buying 10–15% under your max is the sweet spot between building equity and sleeping well.
FAQ
What mortgage can I afford on an $80K salary?
Roughly $248,000–$295,000 on a 30-year loan at 6.5%, per the 28/36 rule. That is $1,866.67/month max for all housing costs.
How much home can I afford on $80K?
About $280,000–$315,000 with 10–20% down. With 20% down on a $300K home, your P&I is ~$1,517/month plus ~$300 taxes and insurance.
What can I afford with an $80K salary?
Beyond housing: a ~$35K car (15% of take-home ≈ $810/month all-in), rent up to $2,000/month (30% of gross), and ~$1,080/month in savings on a 50/30/20 budget.
Is a $350K house too much on $80K salary?
It is a stretch. A $350K home with 10% down means a $315K loan → ~$1,991/month P&I alone, over the $1,867 guideline before taxes and insurance. You would need roughly $98K of income to carry it comfortably, or 20%+ down plus a lower rate.
How do debts change what mortgage I can afford on $80K?
Every dollar of monthly debt above ~$533/month (the $2,400 back-end cap minus the $1,867 housing budget) comes straight off your housing allowance. $1,200/month in debts cuts your mortgage range to roughly $142K–$190K.
How does a combined $80K income affect mortgage approval?
Lenders combine both incomes and both debts, and usually price off the lower credit score. The DTI math is identical; the paperwork is just doubled.
What is a good down payment on $80K salary?
20% ($56K–$63K on a $280K–$315K home) avoids PMI entirely and is achievable in 2–3 years of focused saving at this income. 10% works too, with PMI of roughly $155/month until you reach 20% equity - learn how to drop it: what is PMI and how to avoid it.
