I tend to stay away from them because I've found that they can become a maintenance issue when not frequently used or used properly, which isn't worth the trouble when most renters aren't expecting to have one.Laundry hook ups are definitely appealing to everyone, but I am phasing out any washers/dryers that I supply in my units because they are a maintenance nightmare.  

I think in general these type of non-conforming units are better used for house hackers who have the opportunity to develop a closer relationship with their renters than somebody who is buying an investment property that will be managed by a third party.

Renters to owners ratio is favorable.   

Also, if a claim is a result of your own fault, that will hurt.Having said all of this, I recommend that tenants carry Renter's Insurance with Landlord As Additional Insured and that tenants be held accountable for damages they incur.

New lease or not I would get a written agreement from the seller and renters on the security deposits.

I have a lot of spanish speaking tenants (or prospective renters) who speak zero english.

I'm invested in the Richmond area market as well (about to close on my 5th property), and I work for Renters Warehouse as their Business Development Manager.

@Josh Skyer This may seem overly obvious but... have you started by discussing the issue with the third floor renters?

bought in October 2019, rehab took 6 weeks, renter moved in Dec 2019, signed a 3 year lease.

When my long term renters move out (getting married, nursing home, etc) I offer to buy all their furniture, appliances, electronics, utensils, etc.
