There is no interest rate, its a flat fee based on the amount borrowed.

You don't need a broker in CA to lend either UNLESS you plan to charge in excess of the usury limits.

California charges a minimum tax of $800 a year per LLC, and more if you have gross receipts in excess of $250k.

if future appreciation is flat or less than inflation (3%) i would sell especially since you already have appreciation. 

The concept here is to get to the point where your tenants pay for your housing expenses, which should give you some excess income to save and invest.These initial steps could get you to a point where you have a few doors and maybe even have your tenants covering your own housing expenses.Think carefully about selling, it seems counter-productive if you want to be an investor.

I planned to do that in 2023 until I save up for the flat.

Also sellers could always in past put co-op at $1 or list with various flat fee firms.
