The goal is to keep these for rentals.I currently own the land personally and am funding the builds with a combination of HELOC and cash - no bank debt tied to these properties specifically.

Take a look at the overall picture, i.e. credit score, debts etc.. to make a decision.

High probability that you’ll uncover an oh-$**** issue that will reduce or eliminate your projected profit. 

Due to my W2 employment I cant have any bad/negative personal debt.

Other ways of using SDIRAs could be to invest in syndications, performing  or non-performing debt, precious metals, raw land, precious metals, mobile home parks, self-storage facilities and more. 

However, we still get beat up on a daily basis over our fees.I left one of the largest PM companies, who had those exact fees, and started my own business with the sole intention of eliminating all of those fees.

I think he is over leveraged to a 90% debt ratio.

If it's a larger debt, I would not offer cash for keys.

And keeps you out of any trouble with debt.

The only thing that I see missing if they are purchasing with hard money debt they may want to factor in 3% - 5% for closing costs (points, fees, title, etc) Thx Zachary!
