The big advantage you have is both of you are on board so you can accelerate your speed of learning and investing.There's nonedhxstuon like trial and error.

I'd recommend trying out several with a trial and seeing what works best for you.

that would be great if I can give it a trial...for CA area.  

I am in my 30 day trial with Siteops by Bently and its got some robust tools but also falls short in the ability to customize a site.

However, we do have to expend the time we have here on earth somehow (and purposely, at least), so we might as well find what gives us joy OR find out by trial and error OR speaking to someone who can help draw it out from us. 

It's kinda like me & dieting - I can't eat donuts in moderation.

Fill out the paperwork, serve the tenant, attend trial (unless they leave willingly), and wait for judgement.

Trial and error.

It does cost money, but there is 7 day free trial ;)Another great source I have used for calculating airbnb projections is this link: Short-Term Projections - Home Havens (home-havens.com)Hope that helps!

Finally, Jeff Hampton, who worked as a personal Injury trial Attorney for ten years did a presentation - terrifying but excellent- on how to protect yourself as a business owner not just in terms of direct booking but overall liability.
