When people mention the Galt Ocean Mile, they usually have in mind something "on the beach". That being said, any 1 bedroom - 1 bath on the east side of A1A (the buildings being on the sandy beach) will start at $200,000 and they will be units on low floors looking at parking lots and A1A street. As you go higher, you get better views but prices escalate up to $319,000 ( 1 bedroom - 1.5 bathrooms will go as high as $414,000).
If you are 55 and older, you can enjoy the Coral Ridge Tower Co-Ops. There are huge 4 independent buildings sitting between A1A and the Intracoastal. Because they are Co-Ops their values are much less than their condominiums counterpart. There is absolutely nothing wrong with those buildings for they offer the same luxury amenities as any of the Galt condominiums. However, you mentioned that you have "not great credit" which will rule the Coral Ridge Towers because three of the four buildings are strictly CASH purchases and the one building that will consider mortgage purchases, there are only two lenders who will loan on CO-Ops but they need at least 40% cash down (or more) and the interest rate is not as great as it would a conventional loan on condominiums.
Before you go any further, you need to call your trusted mortgage broker or banker, figure out your finances, how much you can afford, get a pre-qualified letter and call a qualified professional Realtor to help you find exactly what will be best purchase for you...and don't get too disapointed that it may not be on the Galt.
