@Bashar SalahYou don't have to identify yourself if you want to be a secret agent.Just don't violate local advertising and fair housing rules.

Second, once you've identified how much is left to invest with you'll need to talk to a couple lenders to see what you qualify for. 

I sugges you begin to understand your market: identify the city & sub-city you would like to invest in, do all your homework on the area, make a trip and meet everyone that’s worth your time, take a map and highlight the good and bad areas, identify a realtor that you believe is the best match for your needs and analyze as many deals as you can along the way. 

The goal would be to buy small residential properties for now.I'm just trying to identify any holes in this plan before I execute it to know what I'm getting myself into.

I'm currently in the process of rehabbing a three unit to be used as an owner occupied rental.Have you identified a particular area of real estate you are trying to focus on?

You have already identified the potential problem with financing. 

I would suggest looking at your long term real estate goals and identifying which short term option meets works towards getting you closer to your long term goals.

For me, it was critical to have someone who was knowledgeable about the market, and about home repairs and value and who could identify potential problems that I wouldn't have known enough to ask about. 

If they are in units that have more bedrooms that HUD identified for them, you won't be as successful in raising the rents. 

As an agent you should be able identify a home that has upside potential, buy it for a discount and create equity in the process.
