YOUR MORTGAGE, EXPLAINED
Three sources of home equity, with three different assumptions
Eric describes principal repayment, appreciation and leverage as parts of homeownership. Understanding their differences makes an equity projection more useful and prevents a small down payment from being mistaken for a complete investment cost.

Separate repayment from a price forecast
On a standard amortizing loan, the principal portion of a scheduled payment reduces the balance. Appreciation is different: it depends on the market and property. At an assumed 4% annual growth, $350,000 becomes about $518,085 after ten years. That mathematical example does not establish what a real home will be worth.
Include the costs and the downside of leverage
A small down payment allows a buyer to finance much of the price, but borrowing creates interest expense and repayment obligations. Taxes, insurance, maintenance and selling costs also affect the outcome. Leverage can magnify gains relative to initial cash, but a price decline can also sharply reduce equity. Compare scenarios rather than describing projected appreciation as effortless profit.
Is appreciation divided by the down payment my complete return?
No. That calculation leaves out financing, ownership costs, additional principal payments and the timing of cash flows.
