Home Equity

Start with a realistic market value, not the price you paid or the property-tax assessment. An appraisal is the most formal estimate, recent sales of similar homes nearby are the next best guide, and automated online estimates are only a starting point. Then subtract every balance secured by the house: the first Mortgage, any home equity loan or home equity line of credit, and liens such as unpaid property taxes.

Lenders state the same facts as ratios. Loan-to-value (LTV) divides the first mortgage by the home’s value, and combined loan-to-value (CLTV) divides all secured debt by it. Your equity share is 100% minus the CLTV, so a $400,000 home with $300,000 owed has $100,000 of equity, 25% of its value.

Equity on paper is also more than a sale would pay you. Commissions and closing costs come off the top, and gain above the home sale exclusion is taxable, so the check at closing is smaller.

Equity comes from four places. Your down payment is equity on day one. Every payment then moves some principal from the debt column to the equity column, a slice that starts small and grows as Amortization shifts each payment from interest toward principal. Appreciation raises the value side with no payment at all, and improvements can add value, though rarely dollar for dollar.

Equity shrinks just as mechanically. Falling local prices cut it, and a steep enough fall leaves an owner underwater, owing more than the home is worth. New borrowing turns equity back into debt, and a reverse mortgage shrinks it every month as interest and insurance premiums are added to the balance.

Because most homes are bought with borrowed money, price changes move equity faster than they move value. With 10% down, a 5% rise in the home’s price lifts the owner’s equity by 50% before costs, and a 5% fall wipes out half of it.

Equity can’t pay a bill until you sell the home, borrow against it, or make it earn money. Every borrowing route makes the house collateral, so missed payments can end in foreclosure. The CFPB also warns that using home equity to clear credit cards doesn’t really pay them off: it moves unsecured debt onto your house and can stretch a short loan across decades. These are the main routes, each with its own price.

By retirement, the home is often a household’s largest asset, and much of it is equity. That equity pays no income. The owner still owes property tax, insurance and upkeep, so a paid-off house lowers spending needs without funding them.

Planners usually give retirement equity one of three jobs: paying for a later move such as downsizing or assisted living, standing behind the investment portfolio as a last-resort reserve, or passing to heirs. Heirs generally receive a stepped-up basis, so gain built up during your lifetime escapes capital gains tax.

Equity also matters for Medicaid. Federal law bars Medicaid coverage of nursing-home and other long-term care when a person’s home equity exceeds a limit written as $500,000, or up to $750,000 at a state’s option, with both figures indexed to inflation since 2011. The limit doesn’t apply while a spouse, a child under 21, or a blind or disabled child lives in the home, and the law lets owners lower their equity with a reverse mortgage or home equity loan.
