Your math isnt far off but your idea of prices are. You can buy a 3000+ sq ft nearly new home for 650,000 in SEH. heck you can probably get a new one for that. You could also find a very nice newer home in 92009 this year if you knew where to look and how to find it.
My friends dont fit anything close to what you described. They are two very well educated and experienced professionals but neither drs, lawyers or execs. Plenty of people dont make that kind of money but around here alot do and I know many that make alot more. Heck even waitingforthebottom’s wife has met several women whose husbands make 150K plus. She doesnt get to meet the wives who are working and also making as much (sometimes more) as their husbands.
This is a county of 3,000,000 people! Dont be so naive to believe there arent alot of people making good money one way or another. Where do you think those people want to live….Jamul?
