Hard for a person to imagine living there. 

Online Rent Payment (please tell me you still don't collect rent in person).

The reason being is this Person i never had a lease with or rental agreement comes and goes from the property and is NOT living in it..

I've been on the construction and maintenance side of real estate most of my life.

I follow some real estate investors and want to put some of the strategies I learned into play.A little bit about me: I came to the U.S. in 2019 to study electrical engineering and always tried to learn how to better manage my personal finances.

Does it matter if I keep the rents in my personal accounts?

You definitely want to get with a competent tax advisor for personalized advice.

I recommend getting 5 bids and picking from the top three.As far as you, personally., estimating rehab costs....forget it for now.

(Our personal State Farm Agent recommended them and so far its worked out well) We are in Indiana. 

BP has lease templates for every state which are good, I personally use one from eforms.
