You bought your house decades ago, watched its value rise, paid down the mortgage, and now a real estate website says you’re sitting on $300,000 in equity. That’s an impressive asset, but there’s an obvious catch: you can’t buy groceries with the bedroom wall or hand the electric company a piece of your driveway. Home equity in retirement is wealth, but it isn’t automatically spendable cash, particularly when you have no intention of selling the house. That leaves many longtime homeowners with an important retirement-planning question: what exactly is all that equity supposed to do for you? The answer may be anything from “nothing right now” to funding major future needs, but every way of turning equity into cash comes with tradeoffs.
