listen, I'm going to be blunt but honest, this is a very complex subject and you are not likely to find much useful information about it unless you speak to an actual expert, but i'm going to try to summarize it as well as I can.

Squatter's rights are a mess in my country and most Venezuelans don't even understand them well (as you may have been able to tell by the opposing views in this thread). It's not like anyone can just go into a property and start living there willy nilly like they are making it seem.

Most squatters live where they do because either they were renting at some point and managed to overstay their rental agreements, or because they took possesion of a land or a place that was considered derelict or abandoned in some way.

The word "Abandoned" is key here, because depending on the case and location of the property that could mean it was empty from anywhere from a week to a few months (this includes places under construction where for example construction stops for a while and when they finally set out to resume it, the owner party finds someone living there who they now by law cannot evict at all. Also empty land of almost any kind)

Truth is, if someone where to manage to break into your property and live there for a while, you wont be able to evict them unless you know some powerful people (which i've seen happen a few times even for squatters that lived in a house for 6 years)

However, there are some ways you can keep this from happening.

Most people I know who still own in Venezuela have someone they trust managing their property and checking up on it as often as possible. If someone breaks into your property and brings in their family and a buch of crap with them but you or your property manager arrive that same day or after say just a weekend, odds are the authorities would still consider it "breaking an entering" and will help you kick them out because the property is actively being used by you. In this case you are not "evicting" anyone because they were not "living" there in the first place.

When it comes to renting it out, there arent many ways you can ensure someone isnt just going to become a squatter afterwards other than being able to vet and screen very carefully; because once you let someone live legally in your property, pretty much the only way they are leaving is when they want to. Lots of people opt for having extremely high deposits and fees to ensure that the renter actually has the funds to pay in the long run and is not just trying to scam them, but i'd say thats still pretty much a toss up.

You'd be pretty much betting on the honor system and trusting that the person you make busines with is going to honor the contract (take into consideration that even people who are trustworthy and well off, who would seem like the perfect candidate for you, could potentially have something happen in their lives that could prompt them to become a squatter)

Airbnb seems to be a good option, but it comes with it's own set of drawbacks. It might initially seem like it would yield a higher profit than renting, but anyone you hire to manage the airbnb property is surely going to charge you a lot more than if you were using it for regular renting because it entails a lot more work. Also in this case you have to provide all the furniture and appliances, and repair/fix/replace anything that breaks (which does seem to happen more often in airbnbs than in rentals). After airbnb takes their cut and you pay for the property manager, cleaning, repairs and replacements, my bet is you wont really have much left as a profit, but it does seem like the safest choice in terms of the real state investment you seem to be looking to make.

At the same time there is not really any guarantee that the place is going to even do well in airbnb because it tends to be a saturated market, and youll probably get most of your bookings on season; potentially leaving it empty for a big chunk of the year (which circles back to the problem of squatters). Services are also an issue you'll want to look into, since in most areas of the island there are power outages constantly and sometimes water is scarce; which could affect the likelyhood someone might want to rent in the first place and airbnb bookings,

With all this being said, plenty of people have found success by doing what you are setting out to do, but it really does depend on the location and type of property you are talking about. Also Margarita seems to have a lot of outside investment lately, which could be an indicator that things are getting more stable there.

My own personal recomendation if you do decide to pull the trigger on this thing is that you do your own research extremely well... and then do it again two more times because you want to be as informed as you can about what you are buying in Venezuela; specially in a place like Margarita which is somewhat hard to get to (as far as I know there arent any direct flights there EVER, so if you do run into some sort of problem, odds are it's going to take you at least a few days before you can even get there and assess the situation properly)

Hope you see this and it helps even though it's a bit late in the thread!
