Good evening! A tip lot is a waterfront lot located at the end of a cul-de-sac. It can be a preferred location as you may have quite a bit of waterfront, very little traffic and usually your views are quite nice. If you have any additional questions or if I can help you in any way in your search for a Marco Island or Naples area property, please do not hesitate to call or email any time. My cell phone number is 239-860-7176 and my email address is Michelle@MarcoIsland.com. I hope that you have a great weekend!
