Bottom line is buy as big as you can reasonably buy once you are out of small multifamily. 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

A good Realtor that knows investing should be able to connect you with a great PM in the area where you plan to buy.

Quote from @Veronica Mitchell: I'm looking to see what are some of the multi-unit in and around Chicago area to buy in? 

And using the process buy a new property or properties that you also intend to hold for investment use.The issue for you might be that you purchased this property with the primary intent of selling. 

Thing is, I will need to go DSCR loans from here on out or just stop buying new real estate altogether.

Congrats on buying an investment property.

Groovy @Stephanie Medina good luck and keep us posted on your progress.These sorts of things are problems that no one really things about when buying a property and it is something that should be in their mind.

Once you do get buy something, be sure to look at a cost segregation study for the property.  

I’m under contract with my latest flip, the proceeds of which will pay off the heloc that I use to buy and rehab properties.
