I'm under contract on what I think is a great STR investment (cabin in Blue Ridge, GA) but I want to make sure I'm not missing anything in my analysis. What's your complete due diligence process when evaluating a potential STR purchase? Beyond the standard home inspection — what STR-specific factors do you check before closing?

I've analyzed 50+ deals and bought 6 so I've learned where the landmines are. Here's my process for STR due diligence — goes way beyond a standard home inspection. First, market analysis. Before I even make an offer I pull AirDNA data for comparable properties within 1 mile: average revenue, occupancy, ADR. I find 5-10 comparable listings and note their rates, occupancy, and review count. I look hard at seasonality because some markets absolutely die in winter and you need reserves to survive the soft months. I also check supply trends — if 30 new listings popped up in the last 6 months, that's a red flag for saturation. Understand what brings people to the area and whether that demand is growing or shrinking. Second and most important: the regulatory check. Do this BEFORE spending money on inspections. Is STR actually legal at this specific address? What permits and licenses do you need and what do they cost? Are there day caps, occupancy limits, primary residence requirements? Is there pending legislation that could restrict STR down the road? Read the HOA CC&Rs — every single page. Check if neighboring owners have filed complaints about STR. Look into county tax requirements like occupancy tax and sales tax. I've seen people buy properties only to discover STR was banned in that specific zone. Expensive lesson. Third, the financial analysis. Use CONSERVATIVE numbers — I take 65% of AirDNA estimates because they tend to be optimistic. Calculate all your monthly costs: mortgage (PITI), cleaning, supplies, utilities, software, and a maintenance reserve. Figure out your break-even occupancy — the percentage of booked nights where you make $0. That number should be well under 50%. And always run the worst-case: what if occupancy drops 30%? Can you still cover the mortgage? Fourth, property-specific stuff beyond the standard inspection. How old is the roof, HVAC, and water heater? Those are your big-ticket replacement items. Septic vs sewer and well vs city water matter a lot for ongoing costs and risk. Check internet availability — in rural areas your ISP options might be terrible, which is a dealbreaker for modern guests. Test cell service. Is the property in a flood or fire zone? That affects insurance dramatically. Look at driveway condition and parking capacity. If there's an existing hot tub, get it inspected separately. Then the STR-specific stuff: does the layout photograph well (open concept crushes it)? Does it have a unique selling point like a view, hot tub, game room, or lake access? What's the furnishing cost to get it listing-ready? How far are you from reliable cleaners and maintenance workers? Rural properties can be a nightmare to staff. For Blue Ridge, GA specifically: strong year-round cabin market. Fannin County requires a $300 STR application. Check if you're in city limits vs unincorporated county — different rules. Mountain properties have their own issues: well water, septic, gravel roads, propane heat. And budget for bear-proof trash cans because yes, that is a real thing you'll need.
