What are some unique value-add strategies you've implemented in your multi-family assets? I am talking beyond the typical lipstick on a pig upgrades. Some things I've experimented with lately are minor technology upgrades such as Nest thermostats, built-in wall USB plugs, and digital locks. Typical cost of an upgrade like this is $500 and will get a $30/month premium (72% YOC).
Also interested in hearing about any unique common-area value-add people are doing.
