What % of my home goes on schedule e? Renting through airbnb

[Kevin Gomes]

Hi all,

I am closing on a home in early January and trying to plan accordingly for next year. It is a small 2 bedroom home with a bathroom and kitchen/living area. I am planning on airbnbing one of the rooms out while living in the other. Would I just be able to deduct 50% (yes the guest can use the bathroom and kitchen/living areas) of common area expenses? 

I think i read that I could go either by rooms or square feet? the room i am airbnbing would be a tad smaller, so if I can go by % of rooms that would be easier.

Thanks
