If you rent for the summer months only as a rule the funds are all due prior to check in. Most ALL summer rentals go from Memorial Day to Labor Day.
If you rent a property Year Round your rent is normally paid on a monthly basis.
There are many off-season events in our area - Lewes, Dewey and Rehoboth that you would miss if you are just here for the summer. You can check out capegazette.com/ classifieds and get an idea of rental homes available. I do not do rentals anymore (did for 12 years). I only handle listing and selling of homes now at RE/MAX. Let me know if I may assist you further ! Good Luck! It's a gorgeous sunny 80 degree day today !
I only list and sell properties in the Rehoboth / Lewes area, but work a great rental dept. YOu may contact me directly for further information. I will be glad to send you properties that meet your criteria.
Just a ball park to give you an idea.
If you would like me to send you links on condos/ townhomes in our area email me directly and I will provide you with the information for your review. You can certainly get a good idea of availability searching on Trulia. Let me know if you have any questions or are interested in previewing.
I look forward to assisting you.
