There is a rental house across the street from me. Years ago, a fellow lived there who ran a lawn and plow service. His rigs took all the available parking space on the block, even though he had a large yard...probably was not allowed to park on the lawn. He was a loud mouth bad ass type and occasionally blocked my driveway so I couldn't get out, and threatened me once when I asked him to move. Long story short, as he clearly needed more space, I did a spell to find him a more suitable and affordable location, and in six months he left. I see his rigs around town: the other side of town.
But it didn't end there. Within a month of his leaving, new renters moved in. (sigh) a couple who were brawling, snotty, drunken and frequent arrests. The last straw was a drive by shooting, no one hurt. I rolled up my sleeves again. Get-the-heck-out! In ten days they were out...evicted, or moi? This time, however, I added a caveat that only peaceful renters were welcome. The place stood empty over a year; in a large city with several colleges?! I worried that interference was costing the owner his rightful income.
Third try-I visualized the house all warm and fresh. Nothing about who would live there. After some time, I noticed pickup trucks coming and going with wallboard and paint cans and appliances. Eventually it rented again and these folks have been there peacefully over 10 years.
The only "spell" I used was to see it, feel it, say it and let it go.
