Hey Chris, a few thoughts here.Considering that office is not attached to the house, I wouldn’t add any footage to the total home square footage; however, you could advertise that office space and amount of footage and amenities in your remarks.If you’re a Realtor or are using one for the sale, your local MLS may have fields dedicated to additional footage for other buildings on the property, such as ADU’s.The other point is that typically, perhaps depending upon location, a space needs to have heating to count in the square footage, which this office doesn’t have if I understand correctly.Consider contacting an appraiser to inquire about how they would handle this space on an appraisal, or a Realtor.

Summer months are always popular for both locals and again those from the south looking to escape the summer heat.  

It could be stressful if there is a plumbing or heating issue and you're several hours away. 

But it's a 3/2 and I think I could rent it for $1000-1200, has a lot of NEW things already in it (AC/heating, kitchen cabinets, appliances, flooring) but bedrooms need to be finished remodeling.
