How did you calculate COC return? 48% COC return would be a fantastic deal!!
Note that Airdna NOI includes cleaning fees. So if your cleaning fee is $150 and you estimate 8 stays a month, then about $14,000 of that NOI will go to cleaning.
Obviously you want to get a good idea for your expenses like taxes, insurance, HOA, maintenance, Capex, and utilities. For initial set up you'll also need to furnish the place for (about $15/sq ft) and add closing costs for the loan (2-5%).
If you put 20% down on $737,000 (about $150,000) you're taking out a loan for about $590,000. If you get an interest rate of 7%, your debt service will be $41,300 per year (will more after adding taxes and insurance.)
So true NOI is $68,382 - 14,000 (cleaning fees included in Airdna) = $54,382 . Cash flow will be NOI-debt service 54,382 - 41,300 = $13,082. Cash on cash return will be 9%, which is still pretty good all things considered.
Obviously, you need to do your due diligence. I recommend YouTubing videos about how to analyze a STR deal. Robuilt makes great videos.
I have looked in Blue ridge a lot and given up trying to find a deal. The numbers I was getting were <5% COC, barely breaking even or even losing money. The inflated price of everything and the higher interest rates make things very difficult.
