> that anyone selling a home can attach to the sale

Why would anyone attach that to a sale? I bet that such terms would reduce the money you can get for the house to at least a tenth of the unencumbered value. Simply because it will make all future sales so much more complicated and risky. It would reduce flexibility for the person who now owns the home. (Especially the no-renting rule.) Banks would not touch such transaction with a 20 feet pole so the buyer better has the whole sale price in cash. Which means only wealthy people can buy your house.

You might be grinning about all of these consequences and thinking “yes, this is exactly what i want to achieve”. But what is the incentive here for the home owner? From their perspective choosing this option loses them a lot of money, so who would do this? And why?

Sounds like the home owner could just douse their home with gasoline and light it on fire. From a value perspective it has about the same effect. I predict it would be similarly popular too (that is not popular at all). Which means very few happless people would be stuck with this weird situation, while at the same time the option would have about 0 effect on the wider market. (Maybe it would add some extra legal checks to buying normal unencumbered property increasing the legal costs for everyone. Just to verify that nobody had added such an agreement to that particular property in any point in the past.)
