In two words "due diligence". Ask for credit checks (yes, on a short term rental even if the Realtor who brings you the renter balks); interview the prospects (i.e., ask to meet them in person); and get an appropriate security deposit.
I currently have a client with a marvelous multily family rental home 1 block from the beach in Belmar and both tenants are stellar.
It's all in the effort u put into finding the right tenant.

I am the rental manager in my office and am also a landlord in NJ. I'd be happy to help.
Many summer rentals are vacationers but I find people renting for the winter are oftentimes in transition - perhaps they are in the process of relocating for work or waiting for a home to be built. I would say the majority of tenants expect seasonal rentals to be furnished.
Lastly, think about your rental rate and whether or not pets will be allowed.
Hope this helps,
