Check with CA department of real estate.How did she find you?

Registration in some states can be pretty simple, fill out the form, basically it says "hey, state finance department, I'm providing loans with my money on commercial transactions" they just want to know who you are, where you are and what you're doing.

It may increase your vacancy when tenants discover they can no longer afford to heat their unit.I would add this:Since the TX power grid has proven unreliable and the providers can price gouge (how the justice department will challenge that remains to be seen), you could possibly ask premium rents by adding a generator / transfer switch to each building.

You need to check with your planning/zoning department. 

They probably didn't have a listing agreement with the seller.This is something I can report to Ca Department of Real Estate, and AG office.

There are IRS tests determining who is a 1099 vs W2 and then you have your state specific Department of Workers Comp that will have their own definitions of who is an employee and when you would be required to carry Work Comp insurance.To complicate matters there are a few states where the State itself maintains a monopoly on providing Work Comp insurance and the state is the only place to buy work comp (my state is one of those so I can't even sell myself work comp insurance if I wanted to).Here is an article on the three different methodologies the IRS may use to classify someone as W2 vs 1099.https://www.everee.com/blog/irs-independent-contractor-test/If you are really in doubt call your state's work comp office and ask who they define as an employee. 

Is there a department that I can call to verify income? 

Most of the adults couldn't care less about the Xbox, but seeing a nostalgic arcade cabinet with 60 retro games on it brings back memories - and they are the ones paying the rent  It is all about the pictures too - the standup arcade cabinets are going to give you a bigger bang in that department than the Xbox, but the kids/teens want the Xbox.
