The cost to rent an apartment in Placencia depends on the kind of place you rent and how long you are going to stay.
Here's an example. I manage the house that's next door to me. It has 3-stories, a nice big space, and a little pool in the yard. Two folks came to rent from December to April (the high season). One of them is paying US $1,500 and the other is paying $1,600. Everything is included, but they also have to pay a 9% hotel tax on that.
If you are going to rent long term, a house like the one, I manage would probably cost half that price because, if you rent long term, you will be renting 12 months out of the year. Some people who are renting their properties do not like renting out for the long term because they make so much money during the high season.
So if you are going to be here for a long time, and you are looking for a long term rental of at least a year, you could get a very nice studio or a one-bedroom apartment for $700 to $1,000. That would be in a nice building with everything included.
Most people include everything in the rent, but for long-term rentals, sometimes, there are people who will let the tenants pay their own electric bill or they will bill them for their electric, especially if they have air-conditioning, because some people are not very thrifty in using air-conditioning, which could lead to a high electric bill.
If you are going to rent a 3-bedroom, 2–bathroom apartment in a nice location, that could cost you about $4,000 to $5,000 a month; everything included, except for electricity. That would be a fully-furnished apartment and the rent already includes water, cable, internet, etc.
The units we rent out have security guards 24 hours a day. We also have a yard guy from 7 AM to 5 PM. We have a beautiful place and there are bicycles so you pretty much have everything that you need.
