New mold resistant sheet rock and proper ventilation (we crack the top of the window when showering and run a dehumidifier) will work well 

Income over many years-weather plays a big part is the success of a wash, you want to see REAL numbers for st least 3, more like 5 or 7 years to get a better picture.Sellers mindset-is he really selling 2 of 3.

And in the STR game, reviews are pretty much everything.Assuming you have the hot tub up and running smoothly though, I'd also take some time to focus on what cold weather amenities you can offer to guests to entice them to visit during the colder months when ADR's drop and occupancy falls off a cliff. 

I'm biased towards the spring, but fall is pretty spectacular weather-wise.
