The f/f residential conventional rules indicate a quad with ADU does not qualify.  

Asking in the correct forum will get a better response.Read the RULES!

I made that mistake with a 2 bedroom condo - after 1 year, I had to shut down operations due to HOA rule violations of NO short-term rentals less than 30 days.#8 The 30 day+ rule -  Certain places Airbnb is outlawed or a softer rule is the 30day+ rule.

My advise is to look at property online and see if you can talk with an agent first to see what the rules are for that state.

.🔹 Airbnb is Facing Increasing Restrictions:New York City has implemented strict rules requiring hosts to register and be physically present, effectively banning many short-term rentals.Dallas and Atlanta have passed zoning laws banning short-term rentals in residential areas.California cities like San Francisco and Los Angeles are ramping up enforcement with hefty fines for non-compliant listings.🔹 Co-Living is Gaining Legal Ground:Colorado eliminated all restrictions on the number of unrelated adults living together statewide as of July 1, 2024, marking a major victory for co-living advocates.This week, Jacksonville Municipal Court ruled in favor of PadSplit, voiding citations for “illegal boarding houses” on constitutional and fair housing grounds.Cities like all over like Washington D.C. are considering zoning reforms to allow more co-living developments as an answer to the housing crisis.As Airbnb restrictions tighten, co-living is emerging as a scalable and legally sound alternative that balances affordability, tenant stability, and community needs.

I believe after the holidays the other unit will go quickly.What is the rule to refi into conventional loan?

Quote from @Christian Styles: Potentially able to help you find someone but I would need to know specifically where the property is in order to know who to recommend.  

Also, I would look at rental rates to property values to determine if any areas are around the 1% rule.
