Study the market.

I was studying the market and my rent will be just enough to cover the mortgage and HOA fee now I might to pay out of pocket for insurance but don't want to sell it yet because the area is growing and might have good appreciation in the years that follow.

New builds-broke even in the '08 market on two spec homes, built my own home from the ground up twelve years ago(400k in equity). 

What marketing efforts are they going to do outside of just posting in the MLS.

One strategy is to pursue properties (in your preferred markets) that have been listed for sale for over 90 days (even longer is better).

Most land bank properties, Detroit or Wayne County, are trainwrecks and cost more to rehab than they are worth - unless the market keeps improving.Be careful on the next one, but keep improving Detroit!

I’m planning to move what I have in stock market ($2.5-3Mil) to buy a good realestate.

Every where you turn there are STRs going up on the market fully furnished because they couldn't pay the mortgage and bills with the rental income. 

My thinking is I can not as it probably works as I does in the stock market with my IRA.
