Hold It, Sell It, or Leave It to the Kids? The Bit Nobody Explains

If you've owned a rental for a long time, there's a decision waiting that most people make by default rather than on purpose.

Sell it, and you settle up with the IRS on decades of growth. Hold it until you die, and something quite different happens — one that can wipe out the entire bill your heirs would otherwise inherit alongside the property.

The step-up in basis: the rule that changes the math

When someone inherits property, their starting point for tax isn't what you paid. It resets to what the property was worth on the day you died.

Every dollar of growth over the years you owned it — and every year of depreciation you claimed — simply disappears from the calculation. If your heirs sell shortly after inheriting, there may be almost no gain to tax at all.

That's a genuinely large number for anyone who has held property for twenty or thirty years, and it's why "just hold it" is sometimes the most tax-efficient plan available.

Three things it depends on

How the property is owned. This is the one people get wrong. If you own it outright, or you're in a community-property state, the whole thing resets. But if you hold it jointly with a spouse in most states, only your share resets — your spouse's half keeps its original starting point, and roughly half the gain survives. Worth checking how the deed is actually titled, because it changes the answer by a lot.

That it's still yours when you die. The reset happens because the property is in your estate. Give it to your children during your lifetime and they take over your original starting point instead — the growth and the depreciation come with it. The instinct to "get it out of the estate early" destroys the exact thing people are trying to preserve.

Whether you can afford to wait. The equity isn't spendable while you hold. A plan that's brilliant on paper is no use if you need the money, and there are estate taxes in some states — Massachusetts among them — that apply at levels well below the federal threshold.

Compare the two paths

Our hold, sell or pass calculator puts them side by side: what selling now would cost, against what passing it on would leave. It asks how the property is titled, because that's what decides how much actually resets.

This is one of the few landlord tax decisions where doing nothing is a legitimate strategy — and one where the wrong move, particularly gifting during your lifetime, is expensive and hard to undo.
