The maximum loan amount anyone can access through a HECM is $822,375 in 2021 (up from $765,600 in 2020). Since private lenders issue proprietary reverse mortgages, they're not capped, though. Many private lending companies offer proprietary jumbo reverse mortgages up to $4 million. The largest loan amount you can receive depends on how much equity you have built up and other factors. The initial principal limit, or the total amount you can borrow against your home through a reverse mortgage, is determined by three factors: the value of your home, your age and current interest rates. The more your home is currently worth, the more funds you can get through a reverse mortgage. Older homeowners, especially those over 75, tend to get significantly higher loan disbursements. Current interest rates also affect how much you can take out with a reverse mortgage — the lower the interest rates, the more funds you have available to you.
