Back home more than half the town was holiday houses! Some of them would rent during the off season, then come stay through the holidays. There are people who are happy enough to pack up through peak season & head off on hols, or stay with family or the local caravan park. If you were only staying a few weeks at a time it'd be even easier for them. (Just something to consider)

Mum & dad's next door neighbours used to ONLY have their house outside holidays. They lived there for years, with kids, going between the house & the c'van park. & that was for the owners to holiday let the house, not for private holiday use. (That extra $1000 or so a week for 6 - 8 weeks was obviously worth it I guess.
