Before applying for a HECM, you must meet with a counselor from an independent government-approved housing counseling agency. The counselor must explain the loan's costs, financial implications, and alternatives. For example, counselors should tell you about government or nonprofit programs for which you may qualify, and any single-purpose or proprietary reverse mortgages available in your area.

The amount of money you can borrow with a HECM or proprietary reverse mortgage depends on several factors, including your age, the type of reverse mortgage you select, the appraised value of your home, current interest rates, and where you live. In general, the older you are, the more valuable your home, and the less you owe on it, the more money you can get.

The HECM gives you choices in how the loan is paid to you. You can select fixed monthly cash advances for a specific period or for as long as you live in your home. Or you can opt for a line of credit, which allows you to draw on the loan proceeds at any time in amounts that you choose.You also can get a combination of monthly payments plus a line of credit.

HECMs generally provide larger loan advances at a lower total cost compared with proprietary loans. But owners of higher-valued homes may get bigger loan advances from a proprietary reverse mortgage. That is, if you have a higher appraised value without a large mortgage, then you may likely qualify for greater funds. Location (for example, your neighborhood) is only one part of the determination of appraised value.
