run a google search for todd lackner, he is a san diego appraiser that has been working for/consulting with regulators and law enforcement and he’s gotten a lot done. Here’s an article but there are tons of them, a little digging and you should find some contact info, he should be able to direct you to the right place or might be interested himself.
I was fraternity brothers with todd in college, he’s a good dude, I’d give you his info myself or tell you to tell him i sent you but that would blow my cover as an international man of mystery so you gotta get it on your own.
My last question is why is this a shady deal, seems to be priced right at $203 a foot in mira mesa for a circa 1970’s, but if you say that’s a screaming deal that it must be a scam, i’ll take your word for it and offer my condolences, please wait on those at least another year, that thing has 200k written all over it. I found a neighbor house with a 175k 1999 price, I’d say 250k is overpriced.
