It's a great time to vacation at the beach -- not just because it's summertime, but because it's really a renter's market right now. Many owners are stuck with second homes on the water they can't use. So they're trying to rent them in the summer market at deep discounts. The Boston Globe recently reported that Cape Cod is now a great renter's market. For years the Cape has been a notoriously hard place to find a decently priced rental. But now due to the lack of people willing to rent, owners are offering their places at discounts of up to 20 percent. Just be aware if you're going to do a summer rental up north that the beach season there is shorter than it is elsewhere.

So what's the best way to take advantage of this soft market for rentals? Clark recommends a website called Vacation Rentals by Owner. As the name suggests, it helps you rent directly from owners -- whether it's a home, condo, cabin, villa or apartment! For extra value, be sure to look at "fill in the gap" deals where you rent accommodations that are available in between other renters. But be wary of pictures supplied by the owner. Photography can cover up a lot of sins, as Clark says. He recalls when he was in the travel business and someone showed him a brochure with a picture of a hotel next to a picture of a beach that was nowhere near the hotel! Meanwhile, if you're renting an older property, look to see that it's been renovated within the last three years. And don't be shy about asking for more pictures from the owner. What you get initially may be misleading, so watch out!
