Rural ADU - Occupancy Rates?

[Victoria Igoe]

I'm looking to add an 1,100 sq ft ADU on the back of my land.

Targeting a luxury feel (at budget) featuring a stocked pond for fishing, hot tub, etc. All in, we're estimating the cost to be ~$100k (doing most of the build ourselves).

While we're somewhat central (40-2hrs) from multiple larger tourist destinations (SAV, Hilton Head, St. Simon's), there's hardly any AirDNA comps to gauge occupancy. I'm estimating ~60% occupancy and planning to set flex rates $185-200+ per night. Based on this, I'm targeting >20% CoC. The only thing is, it's a best estimate.

TLDR: does anyone have experience analyzing more rural areas to gauge their STR potential? Any other factors I should be considering? TIA!
