Home Construction/repair contractor (We'll need to fix up the house we're trying to buy in Berkeley)

My dad works in real estate, and has built and renovated and fixed up and bought and sold many houses. I think he has said that he might be interested in helping SIAI with that sort of thing, though probably only remotely, to whatever extent that's possible. Would any of that (anything he could provide by phone or email — information, advice, etc.) be helpful? If so, I'll ask him if he's still interested.

(I wouldn't call him a "rationalist", but within that domain he is quite competent.)
