Find out how hard the water is and how often it needs to be checked and test as per EPA regulations..

I will for sure research about it.As well, isn't there a self-sufficiency test when it comes to properties bought through an FHA loan?

I would start with data the municipality will give you. 

It's how I have found deals, I just talk to everyone and always keep my eyes open from as many data sources as as I can.   

Oh, I have bought many properties in this situation.Here are my pointers/lessons learned:1) Make sure you understand the deposits and they are included in closing2) Make sure you understand your state laws on giving the tenant notices to move out3) Try your best to communicate with the tenant some will freak out when a new landlord is added.4) Get a copy ownership to the new tenant and make sure to get keys5) Inform new tenant by your state laws you need to do repairs and get pictures before damage is done that they claim was pre-existing....bs.6) Be nice but be strict when it comes to paying on time, they will test you.7) Hope for the best, and prepare for the worse. 

I am getting my initial training through Rockwell Institute, and hope/plan to join Keller Williams here in Spokane as soon as I pass the test!

@Jonathan Pacilio before last year these properties didn’t exist so you may not find a ton of data.

No, it just means they have not been tested during an economic downturn.

I would figure all the bookkeeping, phone calls, coordination, etc. wouldn't need to have a license to perform those acts and you could just sign a contract per say with the owner saying I'll provide X services at X fee that I bill you for every month.I even considered going underneath someone else's broker license and just build up from there but the fact that they are going to take a big percentage of my already small percentage off rent just irks me when I'm willing to just build off my systems that I have already built/tested. 

I cannot currently find a source on what that test is, but you should talk with a CPA about this anyway.I just discussed this exact situation with Thomas Castelli last week.
