What is this tool?

Compares the net cost of buying versus renting over a time horizon. Buying includes down payment, principal & interest, property tax, maintenance, insurance, and the opportunity cost of tying up the down payment; equity at the end reduces buy net cost. Renting includes growing rent, with credit for investing the same down payment. Tax deductions, PMI, HOA, and selling costs are omitted — change the assumption fields to stress-test the result.

How to use it

  1. Enter home price, down payment, mortgage rate/term, and monthly rent.
  2. Set the comparison horizon and adjust tax, maintenance, insurance, appreciation, and opportunity rate if needed.
  3. Compare buy vs rent net cost under those assumptions.
