I actually purchased a SF house with a two story detached garage in a nice area of brockton.

I have no reason to stay in Gilbert, other than it's where my family lives currently, so it's nice to be close. 

I have found enough business and made enough money not to need to expand outside of this market.Section 8 is a whole different ball game but I find the program is unique in that it's a 3-party relationship adding the variable of a government agency.

It is nice to hear that she is doing better now. 

The third property has a nice cash flow.I am wondering if there are steps I can take to reduce the cashflow issues of the 2 properties before obtaining another property, like pay down the mortgages or should I just save the cashflow from the third property to pay for any future expenses?

I own 4 two/three flats bought between 2013 and 2020 in Forest Park, Illinois, at low interest rates and prices in 200000's  They cash flow nicely and prices have increased a lot. 

I visited detroit this summer and I was surprised on how nice downtown Detroit was.

Oh nice!

As for the zip code you mentioned, some of the areas in there are nice due to steady rental demand, you just want to be very careful on the neighborhoods you select as some areas will be better than others.

Nice job!
