Help me vet an Airbnb Vacation Rental

[Brad Johnson]

I'm looking at possibly purchasing a beach house and Airbnb'ing it. The general rule of thumb I've heard is to expect 1% of the purchase price in gross revenue, but Airdna suggests this property is almost 2%:

501 s shore, surf city, nc 28445

So, obviously $100k on a $575k property would be a deal, so I also paid the $40 for airdna's market specific data and there is a ton for that area, including a great comp a few houses down (same views/distance to beach). This comp does $43k on 99 days a year, 90% occupancy, $475 daily rate (I assume for the 3+ summer months). So, how does $43k for 99 days of peak season extrapolate for the whole year? 

Even if I use $80k/year and assume $2k/mo in all expenses/maintenance/utilities (is this way low?), it is still a 15% Cash on Cash deal.

Assumptions - 25% down, $15k for furniture, $2k/mo for ALL expenses including maintenance/utilities/tax/insurance, cleaning fees baked into airbnb revenue
