The Red Tide Effects on Real Estate

You’ve probably seen it in the news that the state of Florida has declared a state of emergency for 7 counties along the Gulf of Mexico coast because of the phenomenon popularly called “Red tide”. We have put the term between quote marks because scientists have been phasing out of its usage since red tides are not always actually red-colored and tides are unrelated to the occurrence of said phenomenon, however, the effects of red tide are very real and related to several possible troubles to real estate.

But maybe we’re getting too ahead of yourself, so let’s start by answering what is red tide.

What is Red Tide?

What is Red Tide?When large concentrations of certain aquatic microorganisms (algae) blossom, they release photosynthetic pigments into the water, making it look colored by shades of red that go from rust to blood red. This aspect is what’s called red tide. However, if it ended there, it would be fine and kind of cool. Would render a lot of instagram pictures and horror movie shots, right?

The problem with red tides is that the concentration of this algae is bad. Also known as “HAB”, an acronym for Harmful Algal Blooms, red tide algae produce harmful toxins that can kill marine life and is harmful to humans. Regarding the marine life, the worst red tide effects are the contamination of shellfish. Here’s what happens: some shellfish like clams, mollusks, and oysters store the toxins produced by the algae in their fatty tissue and concentrate saxitoxin, which blocks sodium channels. When animals – not only fish but diving ducks and even birds – ingest the toxins from those algae, it can cause a poisoning paralysis within 30 minutes. And the toxin stays stored on dead fish, so once they rise to the surface, other birds can end up eating them and also dying. So, you see, the red tide effects come in cascades and can be very damaging to the environment.

Now, when it comes to humans, the red tide effects are indirect but also direct. The indirect is, of course, through the ingestion of contaminated shellfish, but humans get directly harmed by the red tide effects through skin contact and also by breathing in “brevetoxins” produced by the harmful algal bloom. Red tide symptoms in humans include respiratory irritation, bronchoconstriction, coughing and wheezing – due to the breathing in of brevetoxins – skin irritation in the case of skin contact, and, in the case of ingestion, drowsiness, diarrhea, nausea, loss of motor control, tingling, numbing or aching of extremities, incoherence and respiratory paralysis. Quite a lot of red tide symptoms, huh?

So, I guess we covered what is red tide. But this is not a scientific blog, so let’s talk about the red tide effects on real estate, specifically Florida, because that’s our neck of the woods; our bread and butter.

The Red Tide in Florida

Red Tide in FloridaPoor Florida. When it comes to natural disasters, it just can’t catch a break. If it wasn’t enough to have several cities within our worst cities for natural disasters list, here is the sunshine state again, making the news regarding a natural disaster occurrence. But, truth be told, the occurrence of Red Tides in Florida is nothing new; the first documented occurrence dates back to 1844 at the same Gulf coast. In fact, not even THIS specific red tide occurrence is new; it’s believed to have started a month after Hurricane Irma ravaged the Gulf in September 2017!

For a number of reasons, though, the red tide in Florida was being kept under wraps. Partly because Irma’s damages were still being dealt with and demanded a lot of time, money and attention, partly because, just like in the movie Jaws, this natural disaster has unpleasant effects on the economy. Remember Jaws? At the beginning of the movie, a couple gets attacked on the shores of the fictitious Amity Island and the sheriff feels the beach needs to be closed so no one else dies. But the greed of local business owners makes the mayor keep the beach open;  they’re days away from summer when tourists flock to the city to enjoy the beach and everyone in town makes a lot of money off of that. The rest of the story everyone knows; the shark ravages the beach and kills a lot of people until the sheriff finally kills it.

Okay, now replace the shark with the red tide effects. The red tide map of Florida starts at the end of the Everglades and goes all the way until Tampa, so these harmful algal bloom damages not only tourism but real estate as a whole in many ways. Think of someone that, knowing that Tampa is one of the best cities to invest in real estate, decided to buy a house near the bay to do some airbnb renting. Hurricane Irma has probably damaged his/her house, but, assuming he/she is smart, he probably had insurance against an Act of God like this. Now, with the red tide in the news, he/she would not be able to recover the damages through renting, because who would want to get a sore throat from breathing the breeze coming through the ocean? And what about the local fishermen and local restaurants? How do they keep their business afloat when all of a sudden there’s doubt regarding their moneymaker’s safety?

But, with gubernatorial elections coming, and insurmountable evidence of red tide symptoms – a huge shark whale appeared dead at Sanibel Island close to Cape Coral, 287 sea turtles have died since October, hospitals within the area had a 50% increase of patients with respiratory problems and other red tide symptoms… – it became impossible not to address the problem.

Besides the state of emergency, financial aid of $1.5 million was also announced to diminish the red tide effects and make sure the algae epidemic is contained. There’s no plan beyond containing, as scientists don’t recommend killing the algae because the effects on the environment might be worse than letting the phenomenon going on. Typically, during winter, because of the lack of rain and increasing wind, the proliferation of algae dies or dissipates, the environment balances itself and things get back to normal.

But for now, for the ending of the summer, it’s been tough for real estate within the Florida red tide map; especially for vacation rentals with a lot of last-minute cancellations. Together with the aftermath of Irma, it’s taking its toll on the population of the cities along the Gulf of Mexico. A good opportunity for Acts of God House Flipper Investing? Looking at the bright side of it, yes. But a tough time for longtime residents, especially the ones who rely on tourism in any form. If the financial aid and the environmental conditions do help and stop the red tide altogether, it won’t be that horrible – only a slow down on the increasingly rising prices of that whole area within the red tide map. But if it doesn’t, if – like the sharks in Jaws – the red tide has several sequels no one wants to see… then it really becomes a horror movie for the people of Florida; with decreasing home prices and all last decade’s infrastructure and tourism efforts put to trash.
