I have a 77k net from a 372k sales price on a property I just sold and wanted to see if it was possible to use that as a portion of monies required for a project that I am looking at.I have a developer friend who has a contract on a parcel of land for 375k that he has yet to close on.

However, my FIL sounds like he has concerns about the refinance portion of the BRRRR method.

Wonderful curb side appeal, so well done on the lawn maintenance portion.

More likely you will send or call to a portion...

The compliance portion of our DD includes everything related to city, county, and state compliance to continue to run the property as a park. 

Or I could actually buy a place cash with the loan from my 401k since the area I'd be starting in in prime for rentals and a large portion of the homes in the area start at about 40k

After selling we would use our portion/equity to purchase new retirement home.

The portion of the property that is not owned by the two family member you mentioned will be inherited with a step-up basis.Thus if your distribution was regarding the step-up basis portion, there will be no tax liability to the heir.
