The spot is airing in 20 markets, including six cities where the tourism board has never advertised before and that are just a short flight away: Dallas; Denver; Houston; Portland, Ore.; Salt Lake City; and Seattle.

I responded to remove the air pocket.

Once everything is air tight, put a professional prospectus together highlighting the strengths of the market, deal, and most importantly you.

How to handle or who to hire for outdoor/indoor maintenance, property management, whether to keep or sell the property, should we buy another property?  

Salt air rusts out all mechanical devices like ac units before their time.  

One of them went well, for a couple grand we put up walls that allowed air flow and a dehumidifier and it rented fairly quickly.

The roof has no air vents at all which is a big surprise. 

A full bathroom will be added in the finished basement, as well as a new kitchen, upstairs bath, updated electric, and adding a condenser to the existing forced-air system.

I agree with Air B&B not being landlord friendly. 

The weather outside also plays a factor (the upper 70s seems to be the sweet spot) but I have identified the windows being the key factor.Has anyone else had an issue where leaving the windows open creates some sort of air pressure differential that pulls a smell out of the walls?
