Opportunity Cost:
This rate is applied to the sum of what your down payment and buyer closing costs would have been if you had bought.
Lease vs. Buy Comparison Summary
Understanding the Comparison:
- Upfront Costs: Initial cash needed for buying (down payment + closing costs) vs. leasing (one-time fees).
- Total Housing Payments: Sum of all mortgage payments (P&I), taxes, insurance, maintenance, HOA for buying vs. total rent and renter's insurance for leasing, over the comparison period.
- Property Equity (Buying): Estimated property value minus remaining loan balance at the end of the period.
- Investment Growth (Leasing): Estimated future value of the funds you *didn't* spend on buying (down payment & buyer closing costs), had you invested them instead.
- Net Worth Change: This is a key metric.
- For Buying: (Final Property Value - Remaining Loan - Selling Costs) - (Total cash spent on non-equity building items like interest, taxes, insurance, maintenance, HOA, and upfront closing costs). It represents the net financial benefit or cost considering equity gain and all expenses.
- For Leasing: (Growth from Investing the 'Saved' Upfront Buying Money) - (Total Rent Paid + Other Non-refundable Leasing Costs).
