Key Inputs to Get Right

The most important numbers are usually the interest rate and the time horizon. Over years or decades, small rate differences compound into large dollar differences, so it's worth sanity-checking the rate against current market data before acting on any result.

Rent vs. Buy

The break-even point where buying becomes cheaper than renting depends on home prices, interest rates, rent growth, and how long you stay. In most markets, buying becomes advantageous after 5-7 years.
