I understand that if I rent this ADU out, then I can have a tax write off on the mortgage payment and insurance payment for the the ADU's sqft portion.

And you avoid things like damaged properties (guest insurance from airbnb or prop manager themselves cover that), evictions, collections, etc.   

Find yourself a good team who builds ADU's has a project management team and of course has all the licenses and insurances to protect your property.Quote from @Michael Adamo: Hi BP Community,I’m exploring adding one or two ADUs to a property I own in the Miracle Mile area, near 3rd Street and La Brea in Los Angeles.

And you now know this, but never, ever, neglect to have a firm contract and SOW in place again.

There is title insurance issued at the time of purchase, so we don't want to invalidate that.

You can try to go after their renters insurance, but since you don't have proof, you're probably not going to get anywhere.

My firm goes to 75% on a cash out, as long as all seasoning requirements are met.

My insurer is Erie, for everything including my umbrella. 

Basically insurance companies looking to relocate people who had to insurance  claims on their property and need a temporal housing.I’m curiouse to learn more on how to tap into this market and rent my properties to insurance companies .thank  you !

How much are you qualified to borrow and what will your monthly costs be for mortgage, insurance, taxes???
