Abandoned "zombie" houses are very common, especially in areas that are predominately renter occupied.

I'm sure you've thought of this, but is that one-day buffer (between renters) thingy turned off?

@Cathy MalmroseAll else aside, your son is essentially a landlord for this time and he could put together a lease agreement immediately (ideally with the help of an attorney), which outlines a security deposit in case of damages, requires the prior owner to obtain renters insurance, who pays utilities and any daily rent- especially a daily amount that’s high if they stay beyond a certain date.This would at least cover the primary points in a leaseback.I’m curious about when and how the sellers made the request to stay past closing that your son agreed to - was it just between the two parties or was the Realtor part of that conversation?

@Drew Sygit They will be permanently filling 2 of the rooms and be paying for them just like any other renter would.

Cleaning fee is a passthrough paid by renter.

The first renter paid his rent through his insurance company.

[3] Do you have a target market for renters?

Your point of lack of housing versus lack of affordability of housing is exactly why it'll be primarily a renter nation, and the allocation of rent to income will tighten sharply.

Just curious, how does buy-and-hold investors willing to hire a property manager help bypass the Renter License Moratorium?

The lower value house usually needs more rehab/maintenance work, and the tenants may not be less demanding "per dollar of rent" than high income renters.
