I guess my question for me is how do you find the best market when trying to invest out of state as I currently live in Orange County California and theres not much inventory for 2-4 units to have cash flow. 

I'm in the DFW metroplex and am looking to do the leg work for BRRR or LT single family investors. 

You might have to do a bit of leg work to find banks that will give you all the way to 10, but they're out there.Good luck!

I will say that Orange County (most of Orlando) is experiencing long delays in permits, so you will need other housing while its being built.

He didn't know his insurance lapsed over the summer, and his son was injured requiring hospital attention--his son broke his leg and it required surgery to fix.

Think avocado appliances, shag rugs, faded orange formica, etc. 

Anyone have any recommendations on morgage lenders for a MFH house hack in the Newark/Jersey City/East Orange area in New Jersey?

I see you're in Orange County.

Can I go ahead and take possession by putting up No trespassing signs and marking the property boundaries with stakes and orange flagging?

I have a feeling if I do the leg work in finding even conventional residential lenders it wouldn't be an impossible feat to find one.
