If you are going to rent a house, you need to decide what you want exactly. How many bedrooms do you want? How many beds do you need for couples, singles, kids... Do you want a pool and spa, or just a pool? Do you want a condo or a stand alone pool house? Do you want a game room? Do you have young children that need complimentary pack and plays, highchairs, or strollers? Do you want TVs in every bedroom?
We personally like to have real beds for everyone in our party and not just pull out couches. We like having a master type bedroom for each adult couple. The more bathrooms there are the better especially if you are traveling with more than one family. We like places that have a lot of deck space and chairs by the pool because we spend a lot of time at the rental house when we go.
Once you narrow down what you want, then start looking for homes that work for you with those criteria. When you narrow it down to 4-5 you can ask for a quote that includes all taxes, fees, and pool/spa heat (if applicable) for your dates. Once you narrow the quotes down based on price, availability and gut feelings, check the tax records to verify ownership and that the property does not owe a lot of back taxes. Once you have done that, you can make a final decision.
Good luck.
