Just be cognizant that the 10-75 unit apartment space (pick your unit range) does not have a 3rd party management model that is dedicated to it in many markets.  

If the seller takes a mortgage from the buyer, the seller calculates the gain as if he/she receives all the money when the sale takes place, then the seller picks up a percentage of the total gain, each year equal to the cash received each year, divided by the total sales price.  

I am new this and I don't know how to go about picking the right market to begin my search.I just ordered some books to read before I actually invest--but anyone who has insight in how to research markets or invests nearby and has input on where I should be looking would  be greatly appreciated!  

First pick a neighborhood that you are either in or close to.

After getting a few deals under my belt and studying the market some, I want to pick up a few buy and holds.

You want 4-5 to pick from.

Pick that one thing (go read The One Thing - Gary Keller).  

I would certainly love to network with you and pick your brain.

And if you pick the WRONG Turnkey provider - make that TWO extra layers of costs!

Talk to some real estate agents in the area and let them know that you occasionally have 'pocket listings'  ( houses that are not on the market or the MLS) for them - they may have buyers who are interested in picking them up from you.
