expensive premium house, $780k, 18mo leaseback guaranteed?

[Adam L.]

so an interesting property has come across my inbox. a SFH home in a premium market here. $780k for a 5BR/3BA SFH in a nice neighborhood. The seller wants an 18month lease back, and will continue living there, just as if they hadn't sold it. The seller is offering $3500/mo rent, plus they pay for all the utilities and yard work. To me it seems like some older couple that wants to cash out of their house, but still live there.

The pictures are nice, looks like a well maintained home.

So what's the wisdom of this board think? Guaranteed leaseback, no vacancy, appreciating market, low operating expenses due to continuing the same occupant.

Is $3500/mo guaranteed for 18mos worth the high $780k pricetag? I'm thinking that well ****, even if they move out in 18months, the house will have appreciated even more and I could resell easily.
