If the house is older than 15 years old and an ADU is added, the original house can become rent controlled.

Bidens are a great example as they are about as high profile as it comes, and as of yet nobody has been able to untangle the weave of exactly how all there entities work, what $ comes from where, and that's with arguably hundreds of thousands of people-hours into trying to untangle it to clearly point to where the $ is originating and who it's going to. 

We just purchased a live-in flip that was originally a SFH, then was converted into a duplex, and we are converting it back into a sfh.

Given your experience and strong financials, you have some solid options:Commercial or Portfolio Loan: These are tailored for investors and can help you avoid personal guarantees, especially since you have an LLC.BRRRR Loan (Buy, Rehab, Rent, Refinance, Repeat): Some lenders offer BRRRR-specific loans with funding for purchase and rehab, allowing you to refinance based on the new ARV once stabilized.HELOC or Cash-Out Refi on Current Rentals: Tap into the equity on your single-family rentals to secure funding for the 4-plex purchase and rehab without high origination fees.Each has pros depending on your cash flow goals and timeline.

I originally paid $250/yr, now its $10,000/yr and rising.

And back to your earlier post, yeah Bee Setups saw my original post too and asked me several times to take it down in order to receive a partial refund.

I suppose you are referring to origination, right?
