The cost to build a home here in Placencia is between US $90 to $120 per square foot. In order to keep your cost towards the lower end of this scale, you would have to use mostly local products. If you wanted to import lots of items, the cost would rise. (Some people use their Qualified Retired Persons Program duty exemption to bring down items for their home.) So, if you purchased a lot for $85,000, you could build a 2,000 square foot house for $180,000 to $240,000, and you would have your complete house for $265,000 to $325,000.
You can buy a lot for around $85,000 (even though there are some for sale for $65,000), which would be a road front property (not beachfront) perhaps with a lagoon in the back so you could kayak or boat out. You could walk across the road, where there are public easements with access to the entire public beach. The lot would have a great sunset view over the lagoon and the Maya Mountains. You would be about 100 meters from the beach. The lot would be around a quarter of an acre, perhaps a bit less.
You should be aware that when you purchase land here, there is a 5% stamp duty on the value of the property, paid by the buyer. If, however, the seller had the foresight to put the title to the property into a corporation, this tax would be legally avoided because the buyer would just buy shares in the corporation, as opposed to buying the land, and the title doesn’t change hands.
