Any chance it wasn't the husband you met at the unit and it was a boyfriend?

This is tilt-up concrete panel building (so not your basic metal tin).  

With a duplex, you can do STR, MTR, or long term rental on the unit you don't occupy and those options might give you a substantial boost in CASH FLOW.Yeah living in that duplex might not be as nice as that newly constructed SFH but the VERY small sacrifice now will pay HUGE dividend down the road.  

We use a very cumbersome product built for 50+ unit PM Co's, but when we were smaller we used Guesty and liked it except they did not have trust accounting, which I think they do now.  

I am looking for multi family 2-4 units.

I have a question a friend of mine that owns some property said it’s going to be harder for me to get a four unit next because I acquired a duplex first is this true ? 

There are two people living in the unit, one has signed, the other hasn't. 

But I find the C+/B units have the best balance of income and affordability.  

One that is attributed to the top unit and one that will be for the bottom unit.

Layer on the fact you seem to have a small account which suggests you are not getting the same pricing as a client who has many units under one roof where there are greater efficiencies.
