Hank's right; you should have a Realtor.
Look: Real estate agents are good at some things, such as following all the paperwork through the system, knowing the values of properties, and offering negotiating strategies. They're not good at other things. They don't practice law and, while some of them are really pretty knowledgeable on legal issues, that's not their role; that's not their strength.
Meanwhile, lawyers are good at some things. They know (or should know) the law. They know how to read contracts and write contracts. They understand how to protect their clients from litigation, and to defend them when they're subject to litigation. But lawyers aren't good at other things. A lot of them aren't particularly good with minor details. (You want a current copy of the condo's bylaws? A real estate agent will get it to you for just the cost that the condo association charges. The lawyer probably will charge $250 an hour, plus 25 cents per page copying costs. Or you might get a break and the legal assistant only charges $85 an hour.) Some lawyers are good at negotiating, but many aren't. Their view, understandably, is adversarial. And if you want to figure out whether the condo is reasonably priced, and what your offer should be, do you really think the attorney is the best one to provide that information...and at $250 an hour?
I'm not criticizing attorneys. I'm just pointing out that, based on education, experience, and career choice preference, they have their strengths and their weaknesses. In the case of a condo purchase, you definitely need a Realtor. And, yes, you would greatly benefit by having an attorney do what he/she does best: review the paperwork and provide appropriate legal guidance.
Hope that helps.
