The reason being is that there is an over supply of housing in Baltimore City so there really is no reason for the city to be encouraging more units on the market.

They use "secret shoppers" in my neck of the woods.Just brainstorming here.I really appreciate it, John. 

Generally if you are supplying all capital and he is doing all the work you could structure a number of ways. 

Go to a building supply like marjam, Feldman  or any other commercial supply house.

From one shopper to another, I have noticed that the multiplexes here in San Diego proper fly off the MLS after about two weeks (on average).

More demand than supply.

If you cannot get rid of them through vigilant housekeeping and extermination issues then somewhere they are being supplied all of their necessities.

I have spoken with a real estate agent we have used before and he thinks as long as we can supply the plans, we should be okay but he did let me know there were some additional items that will be needed if the person buying the house has an FHA loan.

I ask myself this because some properties lose some or all the possibility to cash flow because of the mortgage payment.Should I just wait till the supply increases on my area to start investing?

If rental property is in short supply in your town, then rent increases should be occurring.
