My first house needed a lot of work before I could move in. Nothing was structurally wrong with the place. What was wrong is that I had to clean everything inside and out before moving my stuff in. Ever since, I've made it a point to make sure every home I leave is ready for the next guy to move in.
After I get the last of my stuff out of the old place, I go into cleaning mode. That includes mopping the floors, washing the windows, and hiring a carpet cleaning service to steam clean all the rugs. Outside, I'll have one of the local lawn care services mowing the lawn and trimming the shrubs.
Try my tips for getting the place ready for the next guy. Pay it forward, and watch karma come around. The job will be done in no time and you can start working on getting the new place in order.
