Another big mistake is using unlicensed vendors to work on your property. This may save you a couple of bucks in maintenance costs, but in the long run, it costs you so much more. Either you’ll find the work was not done correctly or the materials are not holding up. You’ll need to change the carpet between every single tenant or have the same job done again. Or, something will happen and a tenant will get hurt and sue you. You’ll find yourself in court, where you’ll have to admit to using someone without a contractor’s license. Don’t work with vendors who are unlicensed.
