Are you having luck doing new-build single-family infill projects? 

My long-term goal is to build a portfolio of multifamily rentals while also working as an agent helping investors scale their portfolios.Your experience sounds incredible!

And how do I roll this into a cheaper mortgage (my dti would be too bad for another conventional).Maybe a lender would be able to consider the electric "working" with the proper inspection?

Quote from @Kyle Hess: I'm building a list of tools you could have handy while touring a potential fix-and-flip. 

This, in turn, allows for higher rental rates or quicker sales, directly impacting the ROI.I could remember when an investor purchased an old, three-story commercial building at  a bustling downtown area.

Equity is your frozen cash that you access as it grows to build your portfolio 

Analyze deals, build your network, and educate yourself constantly.If you have access to unique resources (like a VA loan, FHA Loan, or 401K), use them to your advantage!

My husband and I own a rental unit in a condo building in Jacksonville, FL.

Heck, even within offices, the small 1-tenant office buildings suitable for a dental practice or law practice, those are in a very different world. 

You could build or flip less expensive units and sell them to your clients/occupants over time.
