You'll need to credit their rent for the time that the unit in uninhabitable. 

I looked at the HOA fee, and it was only like $280 a month, much too low to maintain that building. 

Looking for some insight if I should wait to purchase in the hopes of more multifamily properties becoming available in the future, if I should make an extremely low ball offer on what's currently listed.

Home Depot, Lowe's, Menards and even local stores like Ace are one stop shops and what you might spend in terms of a little more, you regain in terms of time saved and the ability to sign up for Pro accounts. 

FHA loans are not credit score driven loans as much as conventional loans are.

With that said, the odds of your house getting by a tornado are very low.  

Nevada is also a landlord friendly state with low property taxes.

Houses are still affordable (new construction especially), taxes are low, but I'm concerned if people really rent there (86% owner occupied). 

@James Landeau Some people will say it’s ok to buy a property with low or no money down and depending on the numbers it may be fine.

I'm leaning towards seller financing because my credit history is too short to get as many properties as I want to get this year.
