It varies, perhaps $1000-1800, possibly more. In my second and third place I had modifications made to the units which required numerous addenda to the P&S Agreement so it required several visits and back & forth visits to the sales office & lawyer, all of which increased the price for the services of the lawyer. Bottom line, you can't not have a real estate lawyer. He/she should review the agreement before the 10-day cooling off period ends and to tend to the closing details when buying, or selling and at building turnover (for a new building).
