Are there any expenses outside the usual that I should be aware of? 

Listening to their podcast twice a week (Not your Average Inverter Show - JWB).Made contact and "picked" a property.

I reside in Santa Rosa, CA and property prices are way too expensive, as such looking in out-of-state areas. 

But even if you only wanted to pay your mortgage off faster and not invest, it works as long as you are disciplined, don't increase your expenses w/o at least a corresponding increase in income and basically use the HELOC as your checking account.

Wondering if there is anyone wo can give me more concrete numbers and expectations on expenses and revenue before I buy.Thank you 

One is a wholesaler/flipper, last year he started flipping mobile homes and he's getting average $45k per flip, which is higher than his traditional average $35k per house flip.

You think eggs are expensive now?

However, the average rent in Florence is only $977 per month.

For example, one property was in a distressed market where comparable properties have seen a ~8% decline in average rents over the last 18 months (the period since completing renovation project).
