I agree with @John Underwood that if you can get separates then do that.

As far as the 14.41% in TAT&GET taxes, Mike is right that guests do not like you requesting the additional tax separately so it is better to roll it into the price.

Ok, so I separated this one out (and I just found it) for those with a higher end rental.

Are there separate entrances and exits?

Hey @Ana Mills, I also agree with separate accounts for each STR you have.

Our lot size is 7300 sq ft and main house is 1700+ sq ft.Location: San Jose, CA- We were thinking to potentially design the ADU such that we could have a wall (or a door) that allows us to separate the ADU into a 1 bed/1bath for self use (or rental) and another part which could be rented separately on AirBnB as needed.

You may have to pay an agent to make all these lowball offers, otherwise they may get tired of you wasting their time.3) What can you do to your current house to generate cashflow now or more in the future:- Finish the basement as a separate unit? 

Separate checking accounts not required, but you need to maintain separate books and records.The TREC requirement is correct, but odds of enforcement seem low.

Is complete separation even possible?

It is also a separate loan from your mortgage.Some things to consider:1.
