There are so many options in Downtown Pittsburgh right now, it will depend on exactly what you are looking for. In addition to price per square foot, developers will also charge a premium depending on your view/floor as well as finishes and upgrades (if you are looking for something that is currently under construction). So, price per square foot can actually vary within a building. The other thing you want to keep in mind that will contribute to your cost is the monthly condo fee. It is lower in some of the newer buildings, but also amenities can be less, so that should also be a consideration. That being said, I have seen per square foot costs range anywhere from about $230/sf and up for something like Keystone Lofts (951 Liberty), to over $400/sf when looking at a luxury building like 3PNC. Demand varies upon building. Those with lower fees and more reasonable square footage costs certainly are more in demand than others, but Downtown Living in general is on the rise thank to the increase in amenities available to residents there. I have worked in that area for the last 5 years, and would be happy to help you on your search!!!
