You need a specific property and a specific market study - and a plan - to determine fair market rent for the units you build.They better rent for close to $2000 or more or new construction won’t make sense.Unless one is an experienced developer, this doesn’t strike me as the time to build.That being said, if you can find a smaller project to build, you might proceed.
