I've only been using the flat rate software for about 3 months but it looks like to me it's primarily for small jobs and service work. I think if I used it to bid the condo's my price would be too high to compete against other bids. I believe the vision software is better for this. The Vision software is better for doing takeoffs from a print. With the vision software I would be able to do the estimate for the condo's quicker and more efficiently.
Their website has a free demo. I have the basic version. The cost was about $900 and it works great for the size of job you are talking about.
