In my market, I only have one vendor qualified for appliance warranty work, and the warranty companies paid him half his standard fee for each service call. 

Call the contractors closest to your building and see if they can help or know someone.

Hey Ashley So I would invest in a software like prop stream. you can make a list of landlords pretty easily with a software like that.

So there's not a way to know unless you find out from the seller directly.

Call cops if they keep returning. 

Call every local investor agenda (look at the agents that have investment property listings and call them) and call every local landlord that owns multiple properties (you can get lists off of Deal Machine).

Quote from @Barbara Potts: Mike, thank you so much for your response!  

Quote from @Yael Doron: Hi Brian,Seems you know alot... would it be ok if we could have a quick call?

I have the contract to use them sitting in my email now so I saw a preview of all the data and it's pretty incredible.

Same as insurance why call John Doe's insurance shop down the road when you can call StateFarm for example and save money directly.
