Knob and tube is very difficult to insure. 

Hello,I am a real estate investor located to Southeast MA, I own and manage a small portfolio of 23 units and am looking to expand and scale out of state as the returns and market have been quite difficult in my area: due to CAP Rates, specific building class I am looking to invest in, and rising interest rates/minimal inventory, as well as it would be nicer to be diversified and in a more landlord friendly state.  

I've been self-employed for only 6 months, and loans are proving difficult to come by despite my great credit (not to brag, I'm moreso frustrated and seeking help).

Given your previous career, your goals, and wanting to diversify your investments, I'm wondering if you might find value in the PassivePockets community, it's a community with private forum dedicated to passive investing in syndications.
