I figure since I cant buy in OC for rentals, I should concentrate on one area to buy homes so at least I'm not driving all around the state to check on my homes.What do people do who live in high priced areas but still want rental properties?

I would concentrate on getting the phone to ring.I think scripts are good to give you a general idea but you don't want to sound like a robot while on the phone.

For instance, if you had a high concentration of say doctor office money, that might not fit the bill for the debt investor to co-invest with you.The ideal co-investing firm for a debt facility is typically not a bank.

Concentrate on investing and continue living a frugal life style.

Having a high concentration of clients from one source is always risky.

Mostly concentrating on multi-family large apartments complexes.I think it makes much more sense to invest in TX rather than CA.If it works for you I host a meetup in Los Gatos, it is mostly dedicated to different topics on buying, holding and operating apartment complexes.Feel free to check it:meetup.com/Los-Gatos-Real-Estate-Networking-Meetup/

That is what you need to concentrate on. 

concentration, mental awareness and a survival instinct are very much in order. 

They don't just concentrate on one type of investing which makes it a great magazine for learning.

However, in exchange for more responsibility, you also get a lot more control over your investment than in a traditional stock, where your only control is to own it or not.Real estate is a concentrated asset.
