Your son is likely paying more than the property is worth, by definition, as the seller would almost certainly prefer a similar offer that was not subject to. 

A couple of us up here in the Bay Area are figuring out if someone could drive down a truck with supplies but I'm donating money first.

However, without more information on what your preferences are, it is difficult to give you good advice.

I can put in touch with a couple of local insurance agencies.  

Consider offering equity partnerships, debt financing with profit sharing, or preferred equity, where investors get a fixed return before you share profits.

I still have enough room with my VA entitlement for a buy and hold in a couple of years, so I'd rather save it for later!

If the other party is a lifestyle buyer, he's going to prefer to own his own property rather than have an investment he/she can't control.

(We are working on a generalized survey to collect info on our buyers/potential buyers so we can make sure we understand who our customers are while trying to dial in their preferences and patterns.)You are doing great things. 

After a couple years and a couple different programs I can confidently say skip them all except Vena Jones Cox's the Guru Manifesto.
