When a vacationer has a choice of ski lodge condo (right next to the slopes), casino hotel, motel, or house, they often choose the former before the latter.  

Are you able to self manage and not pay mgmt fees to the resort?

Especially considering the no income tax (you just make up for it in property taxes)We do have some great growing cities, amazing schools (public and private), the white mountains, skiing and beaches so I would say NH typically has more of a draw for those looking for recreational activities. 

One of my hs classmates makes a good profit on an AirBnB he runs out of a second unit in his own home, he is big into the hiking scene like @Al Bigonia , and has many guests who come here for that or skiing.

Many foreigners live in resort destinations such as Los Cabos and Puerto Vallarta.

From there I would just say treat it like a business, and the sky's the limit. 

I would think that using your retirement fund would be a last resort.

Not sure still educating myself in all things real estate, the sky's the limit.

I am not  independently wealthy - so ski-resort areas are likely out!

Also why short term rental-are you in a resort area?
