This has been discussed previously on Bigger Pockets and online, but answers are unclear (the online blog entries conflict wildly, see below for a couple of examples). 

@Ernesto Uribe Investing in California can be difficult as the barrier to entry can be high. 

Hi I'm trying to find a handyman/professional for removing rats/mice in the attic and sealing entry points in our investment property in Riverdale , GA.

I would demand that they post notice on the door for entry or tell them you need to renegotiate price for "unknown damages" in the unit.

A few more specifics, are you looking for one with a common entry area?

I can do that but I need the legal particulars about how projects are paid for, entry and exit strategies for partners, percentages of profit (based on input), the concept of sweat equity and personal expertise invited to every deal.

Entry should be during reasonable hours and only for such legitimate business reasons such as inspections, repairs, alterations, improvements, supplying necessary services, or showing the unit to potential buyers or renters.

The biggest difference being that 1-4 unit properties are an easy entry point so you have a lot more demand, and that demand drives up prices regardless of rent levels. 

Everyone wants in and it is still an approachable entry point, so prices are getting bid up so high by novice buyers that there is no return left, and typically cash flow negative if you outsource management.  

Like most major metro cities it has a wide variety of opportunity but a shortage of affordable housing, much lower costs of entry and lower avg DOMs across the bed counts relative to other major cities.
