5% rent hikes double fast
A steady 5% yearly rent increase roughly doubles your rent in about 14 years (rule of 72).
We simulate month-by-month over your chosen horizon. For buying, we estimate mortgage payments, property costs you enter (tax, insurance, maintenance, HOA), and home value growth. Equity is the home value minus the remaining loan balance. For renting, we account for rent increases and optional investing of savings.

Adding just £100/$100 to principal each month on a 25-year loan can chop years off and save tens of thousands in interest.
A 10% home price drop on a 10% down purchase wipes out all equity and more—leverage magnifies both wins and losses.
If rent is cheaper than owning, investing the monthly difference at a steady return can outrun home equity in some scenarios.
Over long horizons, property tax + maintenance often rival or exceed the interest paid—owning costs aren’t just the mortgage.
