As a renter, aside from parking lots or street parking, a spot exclusive to you or anyone inn your unit should be available at a small fee. Most of the renters in that area charge roughly $100 a month for a single spot. Check with the landlord, if they have more than a few spots collecting dust, they will be more than willing to negotiate a price to fit your budget.
(I frequently visit family in Rockland County)
Good Luck :)
Most of the rentals in Nyack provide at least 1 parking spot. If you are looking for a rental, I can send you listings. If you are unfamiliar with the area, I can send you a Rockaln County map broken down by school district os that you can get a feeling for where the different towns are located.
Good Luck with your search and Happy Holidays
