Dear Dheep,
You seem to be emotionally interested in the subject. More of us
should be!
I might not be the originator of the idea, but I recommend my clients
to plan 2 home purchases during their working life. The key is good
location, NOT the size of the home. One house would be for self
occupation, the other for rent. There are good tax breaks for this and
that will help reduce the cost of the houses. One house in the primary
ownership of each spouse.
Let both be offered on reverse mortgage, which will bring 2 income
streams, plus another from the renting of one house - 3 income
streams!
The progeny can pay to get the properties after parents death. That
way they may also feel that they have earned some portion of the
house, having "taken care" of the parents cash needs in their old age.
Here you have also taken care of the Estate to children part.
Regards
Naveen
