Where the tests come from

Housing costs at 28% and all debts at 36% of gross income are the 28/36 rule lenders publish as guidance; housing costs means principal, interest, taxes and insurance. Chase: the 28/36 rule · edited 25 Sep 2026, checked 21 Oct 2026

Co-op boards: commonly cited; every board sets its own.

Estimates, not a pre-approval, a loan offer or financial advice. A lender decides what you can borrow and a co-op board decides whether to approve you; both look at more than these ratios (credit, assets, job history). Closing costs come from the same model as cash to buy, with tax rates checked there; the tests above were checked 2026-10-21. The mortgage rate is an example, not a quote.
