Questions

How much of my income should go to housing?

A common guideline is that your housing payment shouldn't exceed roughly 28% of your gross monthly income, and total debt payments (including housing) shouldn't exceed around 36% — the '28/36 rule'. Lenders use similar debt-to-income limits to decide how much you can borrow. These are guidelines, not guarantees; your comfortable number may be lower depending on your other goals and expenses. This calculator lets you set the percentage that fits you.

What costs beyond the mortgage should I include?

The mortgage principal and interest are only part of a housing payment. Property taxes, homeowner's insurance, any HOA or condo fees, and mortgage insurance (if your down payment is small) all add to the monthly cost. A payment that fits your budget on principal-and-interest alone can be a stretch once these are added, so include them when judging affordability. The paid planner builds them in.
