Watch-outs
- Appreciation assumptions dominate this comparison and are not guaranteed.
- This simplified model does not replace tax, investment, legal, or lender-specific analysis.
- Buying may be worse for short stays because transaction and selling costs have less time to amortize.
Formula
Total rent sums monthly rent with annual rent increases.
Buying cost includes down payment, principal and interest, and monthly ownership costs.
Estimated equity after selling = appreciated home value − selling costs − starting loan estimate.
Worked example
Over a 7-year period, rising rent and home appreciation can make buying more attractive, but transaction costs and ownership costs can swing the result.

Why include selling costs?
Selling costs can materially reduce equity if you move sooner than expected.
What does buy advantage mean?
Positive means buying looks better in this simplified comparison; negative means renting looks better.

What the result means
The result is a home-budget estimate, not a lender promise. It helps you see the monthly payment, cash pressure, and interest tradeoff before you shop or commit.
How to use it
Compare a comfortable case with a stretched case. The gap tells you how much room you have if the rate, taxes, insurance, or closing costs move.
What can change it
Principal and interest are only part of home cost. Taxes, insurance, HOA or condo fees, repairs, mortgage insurance, and closing costs can change the real answer fast.
