Regarding whether to start with a mortgage broker or a realtor, I recommend connecting with a local realtor who knows the Venice Market well and can help you identify properties that meet your criteria.

I am concerned with rent control as well....The lease is for one yearI know from basement tenant that they signed lease with the sister (but the lease has previous owner's name)if it is fraud - it will be her word against minebasement tenant are probably here illegally and I doubt they would testify

Income may be realized, therefore, in the form of services, meals, accommodations, or other property or in-kind benefits, as well as in cash.In your example however, we're not merely dealing with a timing difference. 

The brokers will have to work with the same few set of insurers-- Sagesure, swyfft, and I think there's maybe 1-2 more.

2) Re the flip, Do you have any experience in construction, or dealing with contractors, as well as your local building department?  

Some" not all builders tend to use the "Builder incentive" tactic like - We will give you $20K towards closing which sounds great but when the builder is setting the market and creating its own sales to move the market it’s a scam!

My only question now is in setting up the loan...

Say that enough times and someone will ask "Well how much would you need?"

Seeing tons of growth here as well for both appreciation and cashflow.
