$283,572

You could comfortably carry about $283,572, but a lender would decline at the price you entered. Here is why, and what changes it.

Housing cost is the limit, not your other debts.

Assuming $75,000 income and a $2,700 monthly budget

The breakdown

Front-end DTI caps housing cost at $1,750 a month — the limit a lender applies before your other debts count.

No federal rate buffer applies to a US mortgage. You qualify at the rate you were actually offered.

Housing cost against your income is what limits this ceiling — measured at the 6.66% rate you were actually offered, since no federal rate buffer applies here. Your other debts are not reducing it yet.

An FHA loan allows as little as 3.5% down instead of the conventional minimum modelled here — not modelled on this page: FHA charges its own upfront and annual mortgage insurance premium in place of PMI, and this screen does not compute that figure.

No down payment fixes this: all four are declined at this price. The scenarios page shows how far off each one is.

Above the monthly ceiling you set.

Cash needed at closing

The distance between what you can carry and what a bank will sign.

Both ceilings, derived line by line.

Monthly debts
Key lever

No monthly debts entered — and at this price the first $100 would cost you nothing, because housing cost is the binding constraint.

That changes the moment total debt service becomes the limit.

Amortization (years)

Different, not stricter. These conventional programs set no citizenship or immigration test; instead they ask that you have not owned a home you lived in for a period defined by the program. Check the ones you are counting on.
