How the amount is worked out

  1. Maximum claim amount: the lower of the appraised value and the 2026 HECM limit of $1,249,125.
  2. Principal limit: maximum claim amount × HUD’s principal limit factor for the youngest borrower’s age and the expected rate (in 1/8-point steps, with a 3% floor).
  3. Mandatory obligations: 2% upfront MIP, origination fee, other closing costs and any mortgage or lien payoff.
  4. Net available: principal limit minus mandatory obligations.

Worked example

Age 70, $400,000 home, 6% expected rate: factor 0.415 × $400,000 = $166,000. Subtract $8,000 MIP, $6,000 origination and $3,000 other costs = $149,000. In the first 12 months you can take up to $82,600, the 60% limit less those costs.

What the expected rate is

For an adjustable HECM it is the lender’s margin plus a 10-year index rate; for a fixed-rate HECM it is the note rate. A higher expected rate means a lower factor and less money, which is why a 1-point change moves the result by thousands.

Costs that keep running

Annual MIP of 0.5% of the balance and interest are added to the loan, so the balance grows over time. You still pay property taxes, insurance and upkeep; falling behind can trigger the loan becoming due.

An estimate from HUD’s published factors. A lender’s quote uses your exact expected rate, appraisal, closing costs and any set-asides, so it will differ. HUD-approved counseling is required before you apply.

Frequently asked questions

How much can I get from a reverse mortgage?

It depends on the youngest borrower’s age, the home value up to $1,249,125 in 2026, and the expected rate. At 70 on a $400,000 home with a 6% expected rate, about $149,000 after upfront costs.

Do you make monthly payments on a reverse mortgage?

No principal and interest payments are required while you live in the home and pay taxes, insurance and upkeep. Interest and MIP are added to the balance.

Why can I only take part of it in the first year?

HUD limits first-year draws to 60% of the principal limit, or mandatory obligations plus 10% if those are higher.
