Do not start with the maximum bank quote. Start with a payment you can live with.
This guide is written for readers in United States using USD. Pair it with the calculators below so numbers and narrative stay consistent.
## Step 1 — Fix the monthly ceiling
Use after-tax income from Net salary, not gross. Many households keep housing (loan + rates/HOA + insurance) under ~30–35% of net. Plug a payment into Mortgage payment and work backward to principal.
## Step 2 — Deposit and cash at the table
Run Down payment and Closing costs (and Transfer tax where relevant) before you fall in love with a listing. A 5% deposit with thin cash reserves is a stress plan, not a starter plan.
## Step 3 — Only then rent vs buy
Rent vs buy is useless if the mortgage payment already breaks your budget. In United States (USD), keep the tax model us-federal-fica in mind for deductible interest or transfer taxes — rules differ; this site is educational only.

Key takeaways
- • Treat every number as an estimate until it matches your payslip, bank quote, or official form.
- • Change one input at a time so you know which lever moves the result.
- • Use related calculators to complete the decision chain (income → tax → housing/credit → savings).
- • For United States, prefer local defaults and USD amounts over foreign templates.
