As in all cases of financial lending, the flexibility comes at a price. A reverse mortgage is a loan using your house and is referred to as a "rising debt, falling equity" kind of deal.

To compare reverse mortgage to a more traditional one, the type of mortgage commonly used when buying a house can be classed as a "forward mortgage". To qualify for forward mortgage, you must have a steady source of income.

Because the mortgage is secured by the asset, if you default on the payments, your house can be taken from you. As you pay off the house, your equity is the difference between the mortgage amount and how much you've paid. When the last mortgage payment is made, the house belongs to you.

On the other hand a reverse mortgage process doesn't require that the applicant have great credit, or even that they have a steady source of income. The major stipulation is that the house is owned by the applicant.

Generally, there is also a minimum age required as well, the older the applicant, the higher the loan amount can be. As well, reverse mortgages must be the only debt against your house.

Differing from a conventional "forward mortgage", your debt increases along with your equity. Instead of making any monthly payments, the amount loaned has interest added to it - which eats away at your equity.

If the loan is over a long period of time, when the mortgage comes due, there may be a large amount owed. Furthermore, if the price of your home decreased, there may not be any equity left over. On the flip side, if it was to increase, this could allow for an equity gain, but this isn't typical of the marketplace.

When deciding how to draw money from the reverse mortgage, there are a few options; a single lump sum, regular monthly advances, or a credit account. There are conditions in this kind of mortgage that would warrant the immediate repayment of the loan; the mortgage will be due when the borrower dies, sells the house, or moves out.

Failure to pay your property taxes or insurance on the home will undoubtedly lead to a default as well. The lender also has the option of paying for these obligations by reducing your advances to cover the expense.

Make sure you read the loan documents carefully to make sure you understand all the conditions that can cause your loan to become due.
