I'd also look at other things like the size of the home (and rooms), layout and size of the lot. 

Is this happening to all of the floors in the house or just some of the rooms?

We use Rhino in our property management portfolio in Grand Junction, Colorado.

In areas that are very tourist-desirable, like coastal/beachfront resorts in FL tiny homes can provide an alternative to higher priced hotel rooms and attract a younger clientele that is not looking to book the large (sleeps-12-at-a-time) condos.

I had a primary condo I lived in, a 2/1 I househacked and rented out the second room.

So now we have to scrutinize every email from them to make sure they aren't offering a sale on room rates.

This house was very nice and clean (build later 1980) My tenant recently claimed there is mold on 1fl (it is like basement as there is no window, it is next to garage) When i see, the mold is not only one area but it seems widely spread on the ground floor (laundry room, wall, celiling etc) Since it is OOO investment, it is not easy to deal with mold issue.

However, if you use a more traditional product, you may have some wiggle room. as far as the cash out/refinance goes, different lenders have different overlay.

Building a closet in the bonus room addition to allow the property to be legally listed as a three bedroom.

Ask them who the biggest player in the room is.
