Owning a condominium on the beach is a great way to vacation but it can also involve a big expense and a lot of work. If you don't live in the condominium year-round, renting it out can help to offset the high cost of a mortgage payment - and that's where the work comes in. Keeping your unit rented when you're not staying there can be a full time job. The easiest way to keep the money coming in from your investment is to turn over the renting to the office of your condominium and let them schedule renters to stay there when they get inquiries.

Condominium associations often use a grading system to rate the units on their rental program to determine the attractiveness of each unit. Associations always want to represent themselves as positively as possible to any potential renters. They can help spread the word about their property and amenities, and that may leave a better impression with their customers. This means that the units with the best rating get rented first and more often than ones that are not so highly rated. Of course, even the lower-rated units rent when it's the fourth of July or there's a special event in town, but when the event passes, so do the renters - and that means no income.
