Everyone here is going to give you a different opinion.

Perhaps you are talking about something different.

Nomad also held the renter's deposit hostage even after I cleared the transfer with no damages to be charged.I had to remind Nomad there is a difference between “can” and should” , while you “can” hold a deposit longer it “should” only be done when there is a question about damages.My bank liked the guarantee, the disorganization inside Nomad and the horrible vendor management would cause me not to use them again.

I am not sure what the means for insurance payouts, replacement value and property value are VERY different - does anyone know?

That may differ by state.

I'm now considering expanding my real estate ventures into building custom homes, but I know this is an entirely different beast between the required capital, learning curve, time committment, etc. 

No way to say for sure since each lender is different and I have no idea of the terms you need or your FICO, but it is typically the prime rate plus a couple of points.

You can hire a few different virtual assistants on a website such as Upwork.com, train them on how to skip trace, and stick with the one that is the best. 

Actually I talked to 6 different multi family mastermind groups.

After going through appraisal and all the applications process, they rejected the loans, over how HOA consists of too many investors vs homeowners, I then picked another unit in different community, did the same process, then they rejected the another execuse over HOA, It costs me several months times of refi and I requested the refund of appraisal fee and didn't get this refund.
