So your resident calls you up. No water pressure from the shower. They have been putting up with it for months, but now it is terrible. Your plumber goes out, and $100 later it is fine. The problem? Dirt, sediment, and sand in the shower head. An avoidable expense? You bet, but you need to have your handyman check this when you do the move-in inspections. More owner money is wasted because of the failure to check the most basic things in the rental. Want to anger a resident or lose an account? Ignore these little items that add up in cost and aggravation.
