A $400,000 home is the exact value at which the HECM origination fee reaches its legal ceiling of $6,000, so the two fixed charges of the loan are $8,000 of upfront mortgage insurance and $6,000 of origination, $14,000 in all, or 3.5 % of the value. The amount itself depends on age. At an expected rate of 6.65 % (10-year Treasury at 5.15 % plus an example margin of 1.5 %), the principal limit is $131,200 at 62, $166,000 at 75 and $239,200 at 90. A 73-year-old owner with $60,000 still owed gets a principal limit of $158,800: the loan clears the mortgage and the two charges, leaves $21,280 usable in the first 12 months and $63,520 more after that. With $120,000 owed instead, a 62-year-old would have to bring $2,800 to closing.

Where $400,000 sits in the fee rule

The origination fee on a HECM (Home Equity Conversion Mortgage, the reverse mortgage insured by the FHA) has a formula written in federal rules: 2 % of the first $200,000 of the maximum claim amount (MCA), plus 1 % of the part above it, never less than $2,500 and never more than $6,000 (24 CFR 206.31). On a $400,000 house, the first part gives $4,000 and the second $2,000. The sum lands exactly on the cap.

That makes $400,000 a turning point. Between $200,000 and $400,000, every $10,000 of appraised value adds $100 to the fee a lender may charge. Above it, the fee stops rising while the loan keeps growing with the value, so the fee becomes a smaller and smaller share. The upfront mortgage insurance premium (MIP) behaves differently: it is a flat 2 % of the MCA, with no cap other than the national limit.

Legal maximum origination fee (24 CFR 206.31) and upfront MIP at 2 % of the maximum claim amount. Third-party closing costs come on top and are not included.

Appraisal, title and recording charges are separate. They depend on the county and the providers, so the only reliable figures are the ones on the lender’s cost estimate; the calculator has a field for them.

What a $400,000 house gives at each age

The principal limit is the MCA times HUD's principal limit factor (PLF) for the age of the youngest borrower and the expected rate. Below, the house carries no mortgage, the expected rate is 6.65 % (read as 6.625 % in HUD's table), the origination fee is at its cap and nothing else is charged. The first-year column is what you can use in the first 12 months; the last one is what opens in month 13, before any growth.

$400,000 home, no mortgage, expected rate 6.65 %, upfront MIP $8,000 and origination $6,000 financed. HUD principal limit factor table in force since October 2, 2017.

900.598$239,200$129,520$95,680

The gap between 62 and 90 is $108,000 on the same house. Most of it comes after 75, where the factor climbs faster. In the first year, with no debt, the usable amount is 60 % of the principal limit minus the $14,000 of charges, because those charges count as obligations paid at closing.

With a mortgage still on the house

Many owners of a $400,000 house still owe on it. The HECM must pay that loan off at closing, and the payoff joins the charges as a mandatory obligation. Once obligations pass half the principal limit, the first-year rule switches: the lender may release the obligations plus 10 % of the principal limit, and no more, until month 13. The next table keeps the same house and adds $120,000 of debt.

$400,000 home with $120,000 of mortgage paid off at closing, plus upfront MIP and origination at the cap. Same rates as above.
AgeObligationsFirst 12 monthsFrom month 13Cash to bring
62$134,000$0$0$2,800
65$134,000$5,600$0$0
68$134,000$14,920$280$0
70$134,000$15,440$4,960$0
75$134,000$16,600$15,400$0
80$134,000$18,440$31,960$0
85$134,000$21,000$55,000$0
90$134,000$23,920$81,280$0

At 62 the debt and the charges come to $134,000, more than the $131,200 principal limit, so $2,800 has to come from savings or a sale of other assets. At 65 the loan just covers everything and leaves $5,600. From 68 on, the first year leaves exactly 10 % of the principal limit as cash, because the obligations are above half of it. The rest stays in the line of credit for later.

A simpler way to read it: the largest mortgage this house can clear with no cash from you is the principal limit minus the two charges. That is $117,200 at 62, $140,400 at 70, $170,400 at 80 and $225,200 at 90. Other closing costs lower each figure dollar for dollar.

Our worked case: 73 years old, $60,000 owed

At 73 the factor is 0.397, so the principal limit is $158,800. Obligations are the $60,000 payoff, $8,000 of insurance and $6,000 of origination: $74,000, below half of the principal limit, so the usual 60 % rule applies. The lender may disburse $95,280 in year one; after the obligations, $21,280 is yours to use. The other $63,520 opens in month 13. The monthly mortgage payment on the old loan disappears, and for this owner that is the main change in the monthly budget. The page on paying off a mortgage looks at that case in more depth.

The credit line of a $400,000 house after ten years

An adjustable HECM's unused credit grows each month at the note rate plus 0.5 % of annual MIP. Take the same 73-year-old, but debt-free, who draws nothing. After ten years, at a note rate held at 5.99 %, the available credit would be about $276,609, while the balance, made of the financed charges and their interest, would stand near $26,744. That growth is borrowing room, not money earned, and it ends when the loan becomes due. The rate will not stay fixed, so treat the figure as an order of size. The line of credit page has the method.

Questions readers ask

How much equity do I need in a $400,000 house for a reverse mortgage?

There is no fixed equity percentage. What counts is whether the principal limit covers the mortgage payoff and the costs. On a $400,000 home with no other closing costs, the loan can clear a mortgage of up to $117,200 at 62, $152,000 at 75 and $196,000 at 85 without cash from you. A larger balance means bringing the difference to closing.

Would a $350,000 or $450,000 appraisal change the origination fee much?

At $350,000 the cap is $5,500; at $450,000 it stays at $6,000, the same as at $400,000. Between $200,000 and $400,000, each $1,000 of appraised value adds $10 of allowed fee; above it, nothing. The upfront insurance keeps moving: it is 2 % of the value up to the national limit, so $1,000 more at $450,000.

Is a $400,000 home enough to get monthly payments for life?

Yes, the tenure option exists at every value; the amount is what changes. With no mortgage and no set-aside, a 73-year-old with a $400,000 home would receive about $1,004 a month for as long as the home stays the main residence, sized on 324 months. A mortgage paid at closing lowers that payment, because less of the principal limit is left to spread.

Does the lender have to charge the full $6,000?

No. The $6,000 figure is the most the rule in 24 CFR 206.31 allows, and the same section says a lender may accept a lower fee. When you compare offers, look at the fee and the margin together: the margin sets the expected rate, and the expected rate sets the factor. The calculator lets you set the fee to zero and see the cash it frees.
