I don’t think it would work for everyone, but it does eliminate some headaches. Biggest one is if you need to sell your house to buy. Sale contingencies can be a turn off if other things are equal. I moved into a 2 bedroom apartment in a complex, I didn’t need to ask - once my lease was up i automatically went month to month. I also ended up with flexibility, I didn’t need a particular settlement date since I didn’t need to leave my place. Also had already sold my house so there were no more surprises like something coming up in home inspection. I guess it’s just personal experience, I’ve bought and sold 3 homes, that was the least stressful process.
