Why is rent vs buy mostly about time horizon?
Buying has large upfront and exit costs, so the hold period strongly affects whether appreciation and equity buildup have enough time to overcome those frictions.

Start with your current monthly rent and a realistic annual rent growth assumption.
Model the ownership side with home price, down payment, mortgage rate, taxes, insurance, HOA dues, and maintenance.
Include both closing costs and selling costs so the comparison reflects the real friction of buying and later exiting.
Set a hold period and review the yearly snapshots instead of focusing only on the starting monthly payment.

FAQ
These answers explain the assumptions behind the calculator so users can interpret the output with the right context.

Yes. The comparison assumes the renter invests the initial buy-side cash and any monthly savings when renting is cheaper, which keeps the analysis from unfairly favoring ownership.
The biggest drivers are how long you stay, the mortgage rate, home appreciation, rent growth, maintenance costs, and the expected investment return on saved cash.
