You need only one! Please read the rules of the forum.
Welcome to the forum and Hopefully to Puerto Rico.
As to housing: there are many condos and houses available in the Island, maybe you can tell us a little more about your situation and where you are looking to live:
Typically rental units are found 3 ways:
a) You drive around looking for: "Se Renta" or "Alquiller" signs, most properties are not advertised they just have a sign on the house or fence.
b) Classificados Online: you select the town, price range and type of housing then communicate with the lister of the property, could be a realtor or the owner.
c) Some realtors will also handle rentals, but not that many and do not expect service as they get very little on rentals so their enthusiasm is low. Also most realtors will only show you properties they have listed, for other available properties you need to contact another realtor.
If you are looking for a guide to help you with anything in the island expect to pay around 150-200 a day.
Once we know more maybe we can help you more.
