I looked into these a bit. It seems if you plan to use it for 2-3 years and you really want to sell your house at that point, it might turn out ok for the home owner.
It also seemed the only way to "smartly" smoothly wrap one up is to sell your house.
For example, say you started a reverse mortgage, then 8 years later you want to stop the reverse mortgage but stay in your house ... the payoff amount is painful! And, assuming most people are retired at that point, not like you can easily go out and get a new normal mortgage.
Some example numbers: say you want $2500 per month from your reverse mortgage ... and say interest is 8% ... so each year you are getting $30,000 payments ... so after 8 years you have received $240,000 in money. Yippy! But, then you decide you really want to stay in the house, and you want to stop the reverse mortgage. Depending on the interest and how it is compounded, and other fees, you might owe something like $330k-$350K for that $240K you got.
And at that point if you assume husband & wife are not working, getting social security and other small income (dividends, etc) how the heck are you going to get a $350K loan to payoff & end that reverse mortgage?
But, say you plan to move to a cheaper place to live in 3 years, just short of funds for the next 3 years, but sitting on a lot of home equity ... you start a reverse mortgage and take that $2500 per month (just making up a number here), get a total of $90K from the reverse mortgage over those 3 years ... now that payoff amount might be $100K-$120K ... sell your 2 million dollar house, minus the $100k-$120K reverse mortgage payment and that ain't so bad.
So it seemed to me, short ish term and sell house, had some OK scenarios.
And worse case scenario is long term and want to actually stay in the house.
