Personally I look to find something that will exceed my returns in the stock market (10% cash on cash).

However, because we don’t have much experience with this matter, are relatively new to being landlords, and come from a different culture, we wanted to understand if there are any particular considerations we should be aware of.I heard that it is illegal to ask about religion, national origin, and other personal information when we talk with tenants, even if we don’t have any bad intentions or discriminatory purposes.

However, for personal reasons the tenant is no longer interested in remaining in this rental and wants to be "bought-out" of their "ownership".First and foremost, a verbal agreement just isn't going to cut it and getting a signed legal contract is the first step.

I am looking at a constructing a single family that would extend into the floodway (not Floodzone) of a studied stream.

Personally, I would avoid any sort of Airbnb arbitrage.

It means an extra call/text for whoever is giving notice or letting the person in, but it will make sure it doesn't happen again.

@Bob AsadI personally would not. 

I have personally seen subs who specialize in storm water management systems as well if that's something that is necessary.

It was an illegal 3 family (legal single family with an in law) with a random other unit.

I personally hear from tons of people who think the market will come down, due to the struggling middle class and the fact that it will get worse.
