I concur with @Charlie Cameron. I'm also an active agent / investor in Destin, and my personal STR is performing well. As I analyze additional deals, I've found that the traditional LTR 1% rule is still a very solid means to make an initial assessment. The key to this approach is retrieving a very accurate number for Gross Income. There are pockets along the Emerald Coast that perform extremely well. And then there are other spots that seem to flail. It all depends on your long term goals, of course. Like @Charlie Cameron alluded to, some of the best equipped properties come at high HOA expenses.
As an example, if I bought a condo for $350K, I would want the condo to generate $42,000 for it to be considered (1% of purchase price times 12 months). If I can confidently expect those numbers, then that might be a deal worth investigating. Of course, in today’s market of hyper-appreciation (not a long term indicator of performance, IMO), even $35,000 works.
As an aside (and opinion 😆), If you’re targeting the Emerald Coast, proximity to the water (specifically the beach) is going to exponentially increase your returns. Its why people flock here by the thousands every year! Hope this helps.
