Under these assumptions. The growth rate is held constant, deposits are made at the end of each month, and the home price stays the same while you save. Closing costs, taxes on interest, mortgage approval and lender requirements are not included. This shows modeled savings only; it does not indicate how much to save, when to buy, or what a lender would approve.
