Medicare and its parent, Social Security, are devilish beasts.
They can steal money, homes, cars, and many assets from under the noses of unsuspecting seniors.
Stealing may be a bit harsh, but they can certainly take assets of seniors, in return for that "free" healthcare they receive!!!
Be wary of such a deal as you describe.
To be fair, some people do unscrupulous things to receive that "free" healthcare.
