FAQ
Frequently asked questions
How the calculation works and where its limits are.
How does the rent vs. buy break-even crossover year work?
Buying involves high upfront transaction costs (closing fees, loan origination, agent commissions upon sale). In the early years (typically 1–4 years), renting is often cheaper. As you build equity and home appreciation compounds over 5–10 years, ownership costs drop below cumulative rent.
What is the opportunity cost of the down payment in a rent vs buy decision?
When you buy, your down payment and closing costs are locked in home equity. When you rent, that same capital can be invested in index funds (e.g. at a 7% annual return). This model explicitly accounts for the compounding opportunity cost of your down payment.
What ongoing homeownership maintenance costs should I budget for?
Financial planners typically recommend budgeting 1% to 2% of the home's total value annually for routine maintenance, roof replacement, HVAC servicing, and property upkeep that renters do not pay.
Is this rent vs buy analysis financial or real estate advice?
No. All outputs are deterministic economic models based on your entered assumptions (appreciation, mortgage rates, investment yields). Consult a licensed financial planner or real estate advisor before making purchase commitments.
What should I do after evaluating my rent vs buy time horizon?
If you plan to stay in the home for longer than the break-even horizon (e.g. 5+ years), use our Mortgage Calculator and Closing Cost Calculator to calculate exact upfront cash and monthly cash flow requirements.
