on the G 550.. if grant is like any other air craft buyer.. there are HUGE accelerated depreciation schedules for new airplanes so most RE guys will put little down as possible and finance as much as possible its not uncommon to put only 5 to 10% down when economy is ripping.. 

We're too busy spending billions on aircraft carrier groups and the next sexy line of fighter jets.

It's like having an Aircraft Carrier protect a dingy from seagulls.

My F8F-1 Bear Cat assures you, "that aint me" but I have an interest in aircraft. 

I'm in San Jose now, but not near the airport or any aircraft flight area and I don't have the black dust here.Is the unit near a busy highway or airport? 

I just got back from a Meetup group here in Contra Costa but there wasn't a single fix and flip investor there and everyone seemed to be investing out of state.

I'd contact the Contra Costa County Public Administrator's office: https://www.contracosta.ca.gov/962/Public-Administrator  You might need them to take over and look for a will among the belongings, etc. 

The kitchen was barely the size of that on a aircraft & it had ONE drawer.

Sounds like there are several unhappy customers of Neal Aviation (Garrett Neal is the owner of the company on record)  for being sold bad parts and they're burning suppliers with hot checks for parts for privately owned aircraft (in their more recent business reviews).
