When I'm starting to talk with real estate agents and they ask for more information about me, what should I be providing them?   

As we are just starting our initial research on which markets we would like to focus on, we came across, Shelby, NC.  

what if one starts tormenting the other but always pays rent?

Additionally, with a 7% interest rate, I'm paying a significant amount in interest.On the other hand, if I save up for a down payment on a rental property, once I have enough to purchase the right property, it shouldn't require any additional money from me, and I'll be building equity without needing to contribute more.Does anyone have experience with this?

House hacking is a great way to get started.

If they refuse to leave, start the eviction process. 

I have heard population growth, combined with income to rent ratio  & crime rate is a good start.

I am now reading the Multifamily Millionaire book and basically want to gather some wisdom and knowledge on how to start this investment journey I want to embark upon. 

What's your best piece of advice or tip when starting out managing a STR?

Sometimes they don't get that until a week or two before they're due to start work.
