Every other mortgage on this site shrinks. This one grows. A reverse mortgage lets a homeowner of sixty-two or over borrow against the house without monthly repayments. The interest and insurance are added to the balance instead, and that balance then earns interest itself. On a $720,000 home with ...
Read this before the numbers. A reverse mortgage is a loan against your home that you do not repay monthly, so the balance grows instead of shrinking. You still have to pay the property taxes, keep the insurance current and maintain the house — falling behind on any of those can make the whole loan due. Independent counselling from a HUD-approved agency is required before you can apply, and it is worth taking seriously rather than treating as paperwork. This page is an estimate to help you think, not a quote.
ESTIMATED NET AVAILABLE
$258,960
A principal limit of about $290,160, which is roughly 40.3% of the $720,000 maximum claim amount at age 72, less about $31,200 of upfront costs. In the first year you could take at most $142,896 of it.

This figure is an estimate of the factor, not the factor itself. HUD publishes a principal limit factor for every age from 62 to 90 at every eighth of a percent of expected rate. This page approximates that table, calibrated against published examples, and can be out by a few percentage points. Nobody should sign anything on the strength of it — a lender running the actual grid will give you the real number in about twenty minutes, at no cost.
The balance would pass the home value at about 21y 4m. That sounds alarming and mostly is not, because the loan is non-recourse: whatever the balance says, the debt is settled at the sale price and the insurance absorbs the rest. Neither you nor your heirs can be pursued for the shortfall. What it does mean is that after that point the house is no longer an asset the estate will inherit anything from.

Things this page does not model, which matter. A life expectancy set-aside may be carved out of your proceeds if the lender doubts the taxes and insurance will be paid, which reduces what you receive. Means-tested benefits such as Medicaid and Supplemental Security Income can be affected by holding the money, though Social Security and Medicare are not. Moving out for more than twelve months, including into long-term care, makes the loan due. And a non-borrowing spouse under 62 has protections that depend on paperwork being right at closing — that one is worth raising explicitly with the counsellor.
OVER TIME
This is the only loan on the site where the balance climbs. Nothing is repaid monthly, so interest and insurance are added to what you owe and then earn interest themselves. The red line is compounding; the green line is a house doing what houses do. Where the red passes the green, the insurance you paid for takes the loss.

Enter the home value and the age of the youngest borrower. Age drives most of the answer — the factor rises about a point a year, so a seventy-five-year-old reaches considerably more than a sixty-five-year-old on the same house.
Include any mortgage still outstanding. It has to be cleared at closing out of the proceeds, so it comes off what you receive rather than sitting alongside it.
Set the expected rate and the note rate separately. The first decides how much you can borrow, the second how fast the balance grows, and they are not the same number.
Look at the crossing point on the chart before anything else. That is when the debt would pass the value of the house, and it tells you what the estate is likely to be left with.
