An experienced realtor should be able to handle this for you.
While an attorney may be able to craft some language to your favor or identify issues, for a regular residential condominium it may not make sense in a risk/reward analysis. The seller is likely already paying 6% in realtor fees, and if you retain a realtor of your own, they are paid out of that 6%--you won't see any added expense for hiring a realtor in most transactions. That may not be the case with an attorney--you may have to pay those costs out of pocket while the seller's agent pockets the entire 6% commission. If this were a high-end condo, or a complex transaction with unique financing or other factors that might change your calculus and make it worth the out-of-pocket to hire an attorney, the answer could be different. But for an "everyday" condo purchase, an experienced realtor should be able to get you there with no money out of your pocket.
