Restrictive laws on selling home of person in Nursing Home?

[Chad Stegner]

In the past, I've infrequently purchased homes from people going into nursing homes, and have ran into situations like the owner only being able to sell it (for example) 70% of the homes value. I was under the impression it was the Nursing Home restricting that percentage, but I'm not certain. I've done a lot of researching, but I can't seem to find anything relating to that in particular. I feel like I must have misunderstood somewhere down the line. I haven't bought a home from someone going into a nursing home for a long time and now am presented with the opportunity to do so, so I am trying to get my facts straight so I can make an offer. Can anyone confirm whether there is a restriction of what the owner can sell the home for/what it can be bought for?

TIA!
