@Christian BrownI was there a few weeks ago and I drove by the streets just north of the Casinos "Hard Rock and Harrah" and it felt like a ghost town.

(I sold mine in 2015 and while it was a great price, i wish nowadays that i hadnt sold)  The bay area is a goldmine.

Nowadays you can get most of these information easily from sources on the web like https://www.zipinsight.com/, at that time I did a lot of legwork myself which took a lot more time.

Bay ownership.I have a property I own in Rohnert Park ( 4 acres) zoned mixed use resi.. its right next to the Graton casino.. there is huge housing shortage in your area ... so rentals will stay absolutely full year in and year out.. plus you should get some increase in rents.. but the worse is you make some cash flow.. and your tenants pay down your mortgage and the next thing you know its 20 years later and you have millions in TRUE Equity.. that's one way to go

Just about everyone nowadays.

I am not sure if it is Vegas, me, or investment properties in general nowadays, but I just cant find something!!!

Plus nowadays the states are starting to frown on Sub2 because too many people took the house, rented it out, then didn't make the pays but kept the rent, totally screwing the sellers and renters along the way.I'd still do a sub2 rehab to retail any day of the week, its a good way to keep money costs down, but I wouldn't suggest using sub2 as a long term (more than a year or so) way to own rentals these days. 

I plan to move to the US to be a real estate salesman, which I've been here in Europe for 7 years.I have considered moving to either CA (I'm thinking about San Diego) or FL (no idea yet).I'm not that aware of the market in both those places, therefore I'm looking for some advices from realtors living/working in both those states.I'm aware that to have a better idea I would have to gather all the informations including cost of living, taxes (which I know are far superior in CA).But just for now limiting the discussion about the markets and possibility of earning a nice income and make some good business as a real estate salesperson, should I focus more on FL or CA nowadays ?

Daniel,  Turn-key investments are an extremely viable option for investors and nowadays there are providers in all major markets.  

New casino in that area has brought some good things.
