The point of upgrade hacking is to find fixed costs (things you had to do anyway) and add value through creating work with your variable costs (using better materials, adding simple upgrades, etc.). Knowing this, I’ve discovered that upgrade hacking is most efficient when significant work already needed to be done. It’s very hard to work this angle on “turnkey” properties (those that don’t need any work other than to “turn the key” and open the door) because you have no fixed costs. If you’re buying properties in good condition, there is no reason to upgrade hack.
