Almost certainly more than the calculators are telling you. The figure most sites anchor to, the 28/36 rule, is a household budgeting heuristic borrowed from personal finance writing. It is not an underwriting standard, and no lender applies it. Actual program limits run far higher, they differ from one program to the next, and the same borrower with the same $100,000 income can receive materially different answers depending on which one is used. We are not publishing a purchase price here, because that depends on a rate that changes weekly. We are showing you where the real ceiling sits.
What is the max DTI for a mortgage?
It depends on the program, and the range is wide. Debt-to-income ratio is your total monthly obligations divided by your gross monthly income, and on $100,000 that gross figure is $8,333 before anything is withheld.
| Program | Where the ceiling generally sits | How it is determined |
|---|---|---|
| Conventional | Commonly up to 50 percent with automated approval | Fannie Mae and Freddie Mac automated systems weigh the whole file, not the ratio alone |
| FHA | Frequently approved above 50 percent, and into the high 50s with automated approval | Manual underwrites are more restrictive and rely on compensating factors |
| VA | No fixed maximum ratio | Uses a residual income test instead. The often-quoted 41 percent is a benchmark, not a cap |
| USDA | Benchmark near 41 percent, higher with automated approval | Household income limits apply separately |
These are guidelines, not entitlements. Automated underwriting findings and individual lender overlays both move the actual answer, and a ratio being permitted is not the same as a file being approved. But the gap between these numbers and the 36 percent you read online is not a rounding difference. It is the difference between qualifying and being told you cannot.
What is the 28 36 rule when buying a house?
It is a budgeting guideline suggesting housing stay near 28 percent of gross income and total debt near 36 percent. It originated in personal finance advice, not in lending, and it survives because it is easy to write about.
Applied as a qualifying standard it would disqualify a large share of American homeowners, including many who have paid on time for twenty years. It describes a comfortable household, which is a legitimate thing to describe. It does not describe what a lender will do.
Treat it as one input among several when you decide what payment you want. Do not treat it as the ceiling on what you can obtain, because it is not, and believing it is has kept a lot of qualified buyers renting.
What is the max DTI for FHA?
Higher than most buyers expect, and it is driven by automated approval rather than by a single published number. Files with strong compensating factors are routinely approved well above the 43 percent figure that circulates online.
Compensating factors are the reason. Reserves after closing, a documented history of paying a similar or higher rent, stable long-term employment, and credit depth all push a file forward. This is why two applicants with identical ratios can receive different answers, and why a ratio alone tells you very little about your own outcome.
FHA is frequently the right program for a buyer whose income is solid but whose obligations are already substantial. That is what it was built to do.
Do VA loans have a DTI limit?
No fixed one. VA underwrites on residual income, which measures the dollars left over each month after the mortgage, other debts, taxes, and estimated maintenance and utilities, against a required minimum that varies by family size and region.
This is the most useful thing on this page for anyone eligible. Residual income asks a fundamentally better question than a ratio does. A household with a high ratio and substantial income left over each month can look strong under VA and weak under a percentage test, and VA will see what the percentage misses.
What is considered monthly debt when buying a home?
Recurring obligations reported on your credit, plus a few that are not. The list is narrower than most people fear, and the exclusions work in your favor.
Counted: auto loans and leases, credit card minimum payments, student loans, personal loans, HELOCs, co-signed loans unless someone else’s payment history is documented, child support and alimony paid, and the full housing payment on the new home including taxes, insurance, and HOA dues.
Not counted: groceries, utilities, gas, phone, insurance premiums outside the housing payment, childcare, and tuition.
Read that second list again. Childcare can exceed a car payment and does not enter the calculation at all. That is not a loophole, it is how the ratio is defined, and it means many households qualify for more than their monthly budget instinct suggests.
The Cherokee County wrinkle is that property taxes and insurance sit inside the housing side of the ratio, and the millage rate is not uniform across the county. The rate breakdown and what it costs at several price points is here. Same price, different jurisdiction, different payment, different qualifying number.
Do student loans affect buying a house?
Yes, and how much depends heavily on which program you use. A loan in deferment or on an income-driven plan is not automatically counted as zero, and the method for calculating the qualifying payment differs across conventional, FHA, VA, and USDA.
This is the clearest example of why the program choice is the decision, not a formality. The same student loan can produce meaningfully different qualifying payments under different guidelines, which can move your purchase price by tens of thousands of dollars without anything about you changing.
We refer our clients to a mortgage broker precisely for this, because a single file can be evaluated against several programs without repeated credit pulls. You are free to work with any lender you choose.
One honest caution, briefly. Qualifying at a ceiling and living at one are different experiences, and the guidelines do not know about your retirement contributions or the roof you will replace in year four. Decide where in the range you want to sit. Just make the decision from the real range, not from a magazine rule that was never talking about mortgages in the first place.
