A cash-out refinance can provide liquidity while keeping the property, though it carries risks.

Ohio & Michigan were recently highlighted in the rust belt as good values that cash flow. 

I would lean into a cash out refi.

I was trying to come up with some ideas to up the cash flow.

Many properties will need specialized attention, especially with plumbing, electrical, and historical elements. 

Jonathan, if you want some knob and tube wire for your electrical museum, it's got that too...I'm out of my depth in knowing whether they are marketers or giving sound advice.

I also have five gas/electric meters.

I have been playing the multifamily game for almost 10 years now, and the GRM is one of my least favorite methods personally since it ignores so many important factors (steam boiler versus electric baseboard heat as an example). 

- We had 2 break-in & furnace & HWH thefts there this year:(File a claim ASAP, you'll need:1) Utility bills to prove electric & gas were on2) A police report, proving a break-in3) Pics/video to prove the condition of the property to support theft claimWhat are you doing to mitigate additional damages?

Insurance is expensive, there is a lot of extra maintenance like painting or electric in common areas that don't apply as much with smaller units.
