Two things come up - the age of the properties and the fact that it is not a fully gated community. Some of the subdivisions ARE gated however.
Those would be the 'downsides'.
On a more positive note, the cost of living there is much lower then in the surrounding communities and Membership is not required. However if you do want a golf membership, it is the lease expensive in the area and you get access to 5 courses - 4 on site and a fifth a few miles out west.
Don't be confused by the previous answer! Unless you are staying at the hotel you can NOT play on any of the courses unless you have a membership. Trust me, I live there!

PGA was founded in the early 70's so some of the units are quite old. I rented a cottage there for 3 years some time ago. They have an optional golf membership and some of the courses are world famous and allow you to pay-as-you-play. There is a hotel on the grounds with a spa, restaurants and other attractions. This community was viewed as a "bargain," next to the newer more opulent communities that developed since the late 90's. It is established, and some of the homes were built in the '80's and are quite lovely. Others have a Mediterranean style architecture. There is a variety of townhouse and condo communities within. In some areas the landscaping could be upgraded, but it is still well taken care of. If you are a bird watcher, this is the place for you. Being near the bird preserve, you will be very happy with the birds you see there. Some communities have a "Dated" look, but the home interiors can be updated and beautiful. Because of the hotel and their rental properties, some consider it a "transient" communities, but that is true everywhere and you will have plenty of year 'round neighbors. Upside, it is near I-95 for airport, etc. access. Some areas are gated, some are not. Croquet games were played within, and perhaps still are. The only downside I found was the age of the homes compared to the new ones across PGA Boulevard in Mirasol, and east in Ballen Isles and the other nearby new communities. I found it a great place to live in. If you would like me or one of my team to show you homes in there, get in touch: marilynfjacobs@gmail.com or 561-988-0070. Baskin Palmer Eye Institute is on the grounds, and there is a shopping center on the grounds and across PGA Boulevard. Add up the pros and cons... you will have a wonderful world-famous community to live in.
