Also, make sure you receive a copy of CC&RR's (Community Covenants, Regulations, & Restrictions) BEFORE you sign on the dotted line. For example, can you wash your car on Thursday evening, or can you hang ANYTHING from your windows/balconies/patios/facia? As ridiculous as this sounds where I used to live they refused to allow a veteran to hang an American Flag. The reason: It would not make the community look uniform. In other words, no personal touches were allowed unless it was confined to areas that could only be seen by you.
A lot of this has to do with the HOA's board. I suggest visiting the place around the time everyone would be getting home from work & talk to it's resident's, as well as your personal real estate agent.
DO NOT use the buyer's agent! This person will not work in your best interest (even if they're related). Because the higher the selling cost the more commission they will make.
Above all keep your eyes & ears open. If you've got a gut feeling, there is a reason. I hope this helps you & good luck in your search.
