Vacation rentals ... Split or not to split

[Stephen Scire]

Last year we bought 2 cottages on 1 parcel of land...  neither are winterized & are seasonal since they are located in Maine by the ocean. They are located in a very convenient vacation spot for beach goers. The only utility shared is the water & the land. Separate cable/internet & electric 

Here is my question...would it be wise to condo the properties , keep 1 unit and sell off the other....applying proceeds to my mortgage.

More Background info if needed...
