How it works

The 28/36 rule

Lenders’ rule of thumb: housing should take at most 28% of gross monthly pay, and housing plus other debt payments at most 36%. The tighter of the two sets the price.

The whole payment

Housing means the full payment: principal and interest, property tax, insurance, HOA dues, and PMI while you owe more than 80% of the price.

What it leaves out

Closing costs (often 2% to 5% of the price), repairs and moving. Keep cash for those on top of the down payment.
