How many people have multiple houses?

[Dustytome]

There should be some mechanism to be able to relocate on the same server. Something like you own a house and are allowed to buy one more. Then within 30 days you have to pick one to keep and release the other or the system will return one back to the pool automatically.

That's coming with Shirogane's opening, whenever that may be. It's more immediate of course, you choose to move to the new plot, the old one is up for grabs.
