The criteria varies with each market.. for some markets it has to be a 3+ bedroom + pool,  for many places it's absolute gold to have at least a mother in law suite but best to have 2 or 3 small units, etc etc..There are a ton of seller finance opportunities here as well (not many actually advertise it but they're open to it once you chat with them).

When it comes to criminal history, that is not a protected class... yet. . . .FYI -- I don't know if this topic has been discussed elsewhere on BiggerPockets, but Seattle has moved forward with an ordinance and a lawsuit has been filed by landlords. 

I have been doing flips and rentals for 10 years and I am now going through my first lawsuit.

If you fail to follow the rules, you may open your personal assets to a lawsuit.

Some people add these and call them in-law suites, if they are getting zoning pushback.  

I understand the the pros and cons of holding a property in an LLC - better asset protection should there be a lawsuit but also can be more difficult to get financing.I'm just wondering if there is anyone here who is on the other side of things and have held your apartment building in your name? 

Imagine you have cancelled your umbrella, then you learn you have not been maintaining your LLCs properly and get a lawsuit. 

If they harmed the property with actual damage I would immediately demand payment, send to collections, and file a lawsuit in SC court.  

I would file a lawsuit and file a lis pendens against the house.

With all this NAR lawsuit business going around, I think people believe that a real estate agent slaps the property on the MLS and that's it.
