I had a conversation with my RE Attorney and he says, up to 179 days and then you do something with a verbal agreement.   

@Robert Ellis it looks like you're active today, so I wanted to put this back in your notifications in case you missed it yesterday:

I have learned a tremendous amount from this community and these forums, as well as connected to some great people.I live in Vancouver WA and am a licensed Real Estate Agent for WA (soon to be OR as well :] ) and also am actively looking for investments primarily in the Multi Family space.

Focus on smaller single-family rentals or duplexes as your first deals, easier to manage and less upfront capital than larger multifamily.You could also partner with local property managers in your target market, so you don’t have to handle day-to-day operations yourself.

5-7 days

I can't see how they can tell if days were blocked for personal use or a rental.

If there are utility bills, car payments, that sort of day-to-day necessity items, that's not good.2. 

Reminder to not forget to bump your Airbnb pricing to offset the difference.

Would I have to use a property manager or does padsplit manage the property ?
