A $30,000 salary can buy a home, but only a small one, and the math leaves almost no slack. If you are asking what mortgage can i afford on 30k salary, the lending industry's standard 28/36 rule puts the answer at roughly a $87,000 to $111,000 loan on a 30-year mortgage at 6.5%, depending on whether taxes and insurance are counted inside the budget (they should be). Asked another way, what mortgage can i afford with 30k salary comes down to one monthly number: $700 for all housing costs. Here is the exact math.
The 28/36 rule, step by step
Lenders use two ratios:
- Front-end (28%): Housing costs at or below 28% of gross monthly income
- Back-end (36%): All monthly debts at or below 36% of gross monthly income
On $30,000 a year ($2,500 a month):
- Front-end limit: $2,500 x 0.28 = $700 a month for housing
- Back-end limit: $2,500 x 0.36 = $900 a month for everything
With no other debts, the front-end number binds: $700 is your total housing budget, including principal, interest, taxes, insurance and PMI. Run your own version with our mortgage calculator and check the price side with our home affordability calculator.
From $700 a month to a loan amount
At 6.5% on a 30-year loan, $700 a month in principal and interest alone supports a loan of about $111,000. But that $700 must also cover property taxes and insurance, which lenders count as housing. After roughly $150 a month for taxes and insurance, the principal-and-interest budget is closer to $550, supporting a loan of about $87,000. That gap is why two calculators can give you two different answers on the same salary: one ignores taxes and insurance, the other does not. Trust the lower one.
With 20% down, the $87,000 loan buys roughly a $109,000 home. With 10% down it buys roughly a $97,000 home, and with an FHA 3.5% down payment roughly a $90,000 home, before PMI.
What a $100,000 home actually costs a month
Here is the tight truth at this income: a $100,000 home only fits the guideline with 20% down. The same house costs very different amounts depending on your down payment, because PMI and the loan size both move:
| Down payment | Loan | Principal + interest | Taxes + insurance | PMI (estimate) | Total a month |
|---|---|---|---|---|---|
| FHA 3.5% ($3,500) | $96,500 | $609.95 | $150 | $44.23 | $804.17 |
| 10% ($10,000) | $90,000 | $568.86 | $150 | $37.50 | $756.36 |
| 20% ($20,000) | $80,000 | $505.65 | $150 | $0 | $655.65 |
Only the 20% version fits inside the $700 guideline, with about $44 a month to spare. The 10% version misses by about $56, and the FHA version by about $104. The home that fits exactly with 20% down is closer to $109,000: an $87,016 loan costs about $550 in principal and interest, plus $150 in taxes and insurance, for $700 a month, right on the line.

Debts shrink the number fast
The back-end ratio is where real buyers lose borrowing power. With debts, the lender uses whichever limit is lower:
| Monthly debts | Back-end housing cap (36% minus debts) | Loan it supports at 6.5%, 30 years, after ~$150 tax and insurance |
|---|---|---|
| $0 | $900 (front-end $700 binds) | ~$87,000 |
| $200 (car payment) | $700 (same as front-end) | ~$87,000 |
| $400 (car + student loans) | $500 | ~$55,000 |
On an apples-to-apples basis, $200 a month in debts costs nothing extra here because the front-end cap already binds, but $400 a month cuts roughly $32,000 off your loan. At this income, clearing even one monthly payment before you buy can matter more than a year of extra saving. Check your own ratio with our debt-to-income calculator.
Paid biweekly? Your per-paycheck housing budget
Most $30K earners are paid every two weeks: $30,000 / 26 = $1,153.85 per paycheck (gross), so the 28% housing budget is $323.08 per paycheck. Twice a year you get a third paycheck in the same month. On an $87,016 loan at 6.5%, adding $100 a month pays it off in 240 months instead of 360 and saves about $42,604 in interest.
Should you borrow the max?
$700 a month is the ceiling, not the target. On $30K gross, take-home is roughly $2,186 a month after federal tax and FICA, before state tax, so a maxed-out payment leaves about $1,486 for everything else. Buying 10 to 15% under your max is the sweet spot between building equity and sleeping well. Earn a little more?

FAQ
What mortgage can I afford on $30K a year?
Roughly a $87,000 to $111,000 loan on a 30-year mortgage at 6.5%, per the 28/36 rule. The lower end counts taxes and insurance inside the $700 monthly budget; the higher end is principal and interest only.
How much mortgage payment can I afford on $30K salary?
Up to $700 a month for all housing costs. A $109,000 home with 20% down costs about $700 a month, which fits exactly; a $100,000 home with 20% down costs about $656, which fits with room to spare.
Can I afford a $100K house on a $30K salary?
Yes, but only with 20% down: a $100,000 home with $20,000 down costs about $656 a month including taxes and insurance, inside the $700 guideline. With 10% down it costs about $756 and with an FHA loan about $804, both over the line.
Can I afford a $150K house on a $30K salary?
Not comfortably. With 20% down, a $150,000 home costs about $958 a month including taxes and insurance, well over the $700 guideline. You would need roughly a $41,000 salary to fit it comfortably at 6.5%.
How much mortgage can I afford on $30K salary with debts?
With $200 a month in debts, nothing changes: the back-end cap is $700, the same as the front-end, so your realistic loan stays around $87,000. With $400 a month in debts, the cap falls to $500 and the loan falls to roughly $55,000.
What is a good down payment on a $30K salary?
20% (about $21,800 on a $109,000 home) avoids PMI entirely, but it is a big sum at this income, so an FHA 3.5% down payment of roughly $3,800 on the same home is the realistic entry path, with PMI of roughly $44 a month. Saving the 20% while paying rent takes most buyers 3 to 5 years.
Does a $30K salary guarantee mortgage approval?
No. The 28/36 math is only the affordability ceiling. Approval also needs a qualifying credit score, stable employment history, and a debt-to-income ratio under the lender's cap, usually 43 to 45%. A strong credit file and no other debts matter as much as the salary number itself.
