You earn $85,000 a year, have $40,000 saved, and carry $15,000 in student loan debt. With 30-year fixed mortgage rates sitting around 6.5% in 2026, here is what you can actually afford — not a ballpark, but a number you can bring to a lender.
The 28/36 Rule Applied to $85K
Lenders use two debt-to-income ratios to qualify you. The front-end ratio caps your monthly housing costs (principal, interest, taxes, insurance, and HOA) at 28% of gross monthly income. The back-end ratio caps all monthly debt payments at 36%.
On $85,000 annual income, your gross monthly income is $7,083.
- Front-end limit (28%): $1,983/month for housing costs
- Back-end limit (36%): $2,550/month for all debts combined
You have $15,000 in student loans. If your minimum payment is $175/month, that leaves $2,550 - $175 = $2,375 for housing under the back-end rule. The front-end rule is slightly tighter at $1,983, so that becomes your binding constraint.
What $1,983/Month Buys at 6.5%
Monthly PITI (principal, interest, taxes, insurance) of $1,983 breaks down roughly as:
- Property taxes: $350/month (assumes 1% annual rate on ~$420K home)
- Homeowner's insurance: $125/month
- Leaves $1,508 for principal and interest
At 6.5% on a 30-year fixed loan, $1,508/month services a loan of approximately $238,000. With $40,000 down minus closing costs (budget $8,000-$10,000 for closing), you have about $30,000-$32,000 available for a down payment. That puts your target price range at roughly $268,000-$270,000.
How Down Payment Affects PMI and Your Real Budget
If you put less than 20% down, you'll pay private mortgage insurance. On a $270,000 home with $32,000 down (about 12%), expect PMI of $80-$110/month. That costs you $960-$1,320 per year until your equity reaches 20%.
Here is the math at three different price points with your $32,000 down:
| Home Price | Down Payment | Down % | Loan Amount | Monthly P&I (6.5%) | Est. PMI | Total PITI |
|---|---|---|---|---|---|---|
| $250,000 | $32,000 | 12.8% | $218,000 | $1,378 | $100 | ~$1,953 |
| $270,000 | $32,000 | 11.9% | $238,000 | $1,504 | $115 | ~$2,094 |
| $300,000 | $32,000 | 10.7% | $268,000 | $1,693 | $135 | ~$2,303 |
At $250,000, your PITI of ~$1,953 fits comfortably inside the $1,983 front-end limit. At $270,000, you are over by about $111/month. At $300,000, you are $320/month over the limit — a lender will likely decline that unless you provide documentation of strong compensating factors like a high credit score or significant reserves.
Compensating Factors That Expand Your Range
Lenders can approve loans above the 28/36 thresholds when you have compensating factors:
Credit score above 740. A 760+ score qualifies you for the best conventional rates. It also signals to underwriters that you manage debt responsibly.
Cash reserves after closing. If you have 2+ months of mortgage payments remaining after closing, lenders view that as a buffer. On a $250K home, that means $4,000 kept in savings after the transaction closes.
Stable employment history. Two or more years at the same employer — or in the same field — significantly reduces perceived risk. Self-employed borrowers need two years of tax returns.
Low actual debt load. Your $15,000 in student loans with a $175 minimum is manageable. If that minimum were $500/month, your back-end ratio would cut your housing budget to $2,050/month ($2,550 - $500), and your maximum loan would drop by about $40,000.
The Rate Sensitivity Problem in 2026
At 7.5% instead of 6.5%, the same $1,508/month for principal and interest only services $215,000 — a $23,000 reduction in borrowing power from a single percentage point increase. Rate locks matter: locking your rate for 60-90 days protects you during the purchase process.
If rates drop from 6.5% to 6.0% after you buy, a refinance becomes viable once you have enough equity and the break-even period makes sense. On a $238,000 loan, a 0.5% rate drop saves roughly $70/month — enough to recoup $7,000 in closing costs in about 100 months (8.3 years).
What to Do Before Applying
Pull your credit report before talking to lenders. Errors in credit reports are common — a single reporting mistake can suppress your score by 30-50 points and cost you a higher rate. Fix errors 6-12 months before applying for a mortgage.
Get a preapproval, not just a prequalification. Prequalification is a soft estimate based on stated income. Preapproval requires income documentation, credit pull, and underwriting review — it signals to sellers that your financing is real.
Keep your down payment funds in a stable account for at least 60-90 days before applying. Large unexplained deposits trigger "source of funds" questions that slow underwriting.
FHA vs. Conventional Loans at This Income Level
Conventional loans (Fannie Mae/Freddie Mac) require a minimum 620 credit score, though 740+ gets you the best rates. With 12% down on a $250,000 home, you qualify for conventional — but will pay PMI until you hit 20% equity.
FHA loans require only 3.5% down with a 580+ credit score. On a $250,000 home, FHA down payment is $8,750 — much less than the $32,000 you have available. The trade-off: FHA mortgage insurance premium (MIP) is charged upfront (1.75% of loan amount = $4,200 added to the loan) and annually (0.55-1.05% of the loan balance) for the life of the loan on most FHA mortgages. Unlike conventional PMI, FHA MIP does not automatically drop at 20% equity unless you refinance out of the FHA loan entirely.
At your income and savings level, a conventional loan with 10-12% down is typically cheaper over a 7-year hold than FHA, because conventional PMI drops off automatically. Run both scenarios side by side before choosing a loan type.
