Understand long-term housing costs clearly.
Quick answer: Rent vs Buy Calculator
Weigh rent growth, home appreciation, maintenance, and opportunity cost of the down payment.
Example: $2,400 rent rising 3%/yr vs $520k buy, 20% down, 6.2% mortgage, 1.1% maintenance → break-even horizon might be ~4–6 years (illustrative).
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Buying wins when you stay long enough that transaction costs amortize. Renting wins when mobility or maintenance risk is high - this quantifies the fork.
