I think it likely an appraiser will value your duplex with 2 ADUs via comps with quads, but recognize there is some risk assuming this.  

We’ve slowly been improving our homes the more we’ve built and the more feedback we get from our Buyers2021 – Added 8ft doors throughout the home2022 – Added a new elevation with stone in the front of the home2023 – NO carpet in the bedrooms, LVP throughout the home2024 – Added hurricane impact windows & new color options2025 – Adding Ceiling FansGotta be open to feedback and adjust accordinglyThis can be the difference of your home sitting on the market for 4 months vs 1 month

But I would strongly advise, never letting somebody else do your due diligence on an investment for you. 

It's definitely doable. 

Also, keep in mind that if you do form an LLC, you'll want to keep these under your EIN, not your SSN.Bank AccountCredit CardTitleLoanBookkeeping Ledger

I like umbrella because there is no worry of being pierced for inadequate separation of finances, if sued you have a heavy weight in your corner who has all the consequences of a defeat, and because usually it is reasonably priced (mine today is not so reasonably priced but I believe it is mostly related to the risks of CA).I do understand that the probability of needing the umbrella policy is low.
