Your goal is to buy a place at a great price, and your agent's goal is to mainly help you buy a place.  

But these all factor into your decision.

Mainly have interest in acquIrIng a multi family rentals , also flipping houses, WORKING with PRIVATE MONEY LENDERS .

Location is the biggest driving factor. 

We are converting our house into a rental property and there is an interior security camera (part of a NEST system) in the main living area Is there any reason I have to remove it when tenants occupy the property?

Another point  is, evaluate what these investors' main goal is.

The other main thing to consider is that evaporation coolers really increase humidity in the unit and without ventilation it can cause problems with mold.

My main issue: How did you get the financing for your next property?

You have to consider number of factors before doing this, the property would have to be appraised and would be added to your income for the year in which you make the distribution, likely pushing your tax bracket up.If you simply wish to get into self-directed investing you may want to consider truly self-directed Solo 401k, it has number of advantages over SD IRA such as contributions limits 10X higher, no need for a custodian, checkbook control, exempt from UBIT on leveraged real estate and more.

It's located in an okay neighborhood, not the best from my standpoint, but is close to a main street and an university (12min walk).
