A buddy of mine Patrick runs the new investor subgroup of the AZREIA (Arizona Real Estate Investors Association).Next meet up for that group is May 7th at 6pm in the Keller Williams building located at:1745 E.

I enjoy working with Summit Law Group on all real estate and corporate matters. https://www.summitlaw.com/

Try the big groups like Alamo REIA and the smaller meetups.  

Also do you know of any groups or anything to network with other investors here?

For example, I know groups that will do 70% LTV based on the after repair value, and are willing to pay out the rehab directly to your contractor as needed.

Find local senior care organizations, do enough googling or networking and you'll likely find networking groups where you can connect with folks in the biz then you can track down ownership or operators from there.  

There are also other events that you can find at Eventbrite and several Facebook groups as well.

I would look into converting it into an actual duplex with separate utilities, but I have not had any trouble finding groups of 6 that all know each other.

Outside of the research you have noted, I'd suggest:- go to open houses and look at properties- find your local RE investment group (and join!)

The exception to this was a group of non communicative tenants, i inherited after taking over a property they didn't respond to any posted notices, phone calls or messages requesting information to resolve issues so that process moved pretty quick into eviction, but that's not the norm.
