Buying a home in your 40s or 50s brings different questions than it did at 30 — maybe you are downsizing, buying solo after a divorce, or buying for the first time. The short answer: plan on the down payment plus 2–5% of the price in closing costs, then make sure the monthly payment clears the 28% rule. On a $400,000 home with 20% down, that is roughly $92,000 upfront and about $2,500 a month at recent rates.
The 28/36 rule lenders actually use
Most lenders want your housing costs — principal, interest, taxes, and insurance — under 28% of gross monthly income, and total debt payments under 36%. Exceed those ratios and approval gets harder or the rate gets worse. The “income lenders expect” figure above is the 28% rule working backward from your payment.
Why 20% down is a target, not a requirement
- Below 20% down, you will usually pay PMI — often 0.5–1% of the loan per year — until you reach 20% equity.
- FHA loans allow 3.5% down; conventional loans can go as low as 3% for qualified buyers.
- A smaller down payment keeps cash in reserve, but raises both the monthly payment and total interest paid.
Do not empty the tank at closing
Lenders like to see cash reserves left over after closing — ideally two to six months of payments. A house immediately starts charging you for maintenance; budgeting 1% of the home's value per year for upkeep keeps the dream from becoming a cash-flow emergency.
