@Emily Gowen These types of questions are precisely the focus of my firm.

Build up your portfolio with a professional landlord and then as your portfolio grows transfer the assets over to a larger PM firm for ongoing accounting and management. 

Insurance actually yes my other subto just renewed on the 10th.

You mentioned gross rents of $3400 per month and Principle/Interest/Tax/Insurance of $2500 per month. 

I would google commercial real state firms in the areas you are looking for. 

The law firm handling tax foreclosures for the county put the tennis court lot up for auction.

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

Insurance liability, I personally know 2 families that lost their children in home pools.

To thrive in real estate investing, you must maintain a firm grip on your finances.

I would invest in Sunrise Capital, but I didn't get the impression that they would accept $50K as an initial investment, which I always like to do to try out a new firm (for me) and to diversify geography and risk.
