Since the deals also vary in size (100-400unit portfolios) and asset class (b+ to c- ) I was hoping someone could assist with some support.

This is a time when smart money is selling real estate, if they can find an attractive asset class to invest in with the cash.   

How many units and what asset class @Fas McO'nen?

If you feel comfortable that your intent was to hold it for productive use in investment and something has caused you to change that intent then go for it.  

Or they do cost seg and get 20% short life assets or $5,500 that gets immediately expensed under the new tax law.

A big worry is if anything happens to me how does my family know where all my assets are?

You have instant equity gains that eclipse the cash flow potential and a brand new product with a warranty.

There is an intrinsic value to residential real-estate, unlike many other asset classes.  

And I’m not talking about FHA or government-backed loans, these are either in-house mortgages or commercial products so I would think they have the flexibility to work with me.

I'm not going to spend all my time saving and paying down my personal residence, because the sooner I create another asset (generating passive income), the longer I can build returns from it.
