If a Sim is using an object as it is being repossessed, they will get the money back for the object as if they sold it. This is a great way to get away without paying bills. Just keep track of the cost of your bills. Then, immediately after a bill explodes, switch to Buy mode and pick up every object. Find the object with the price closest to your bills, but expensive enough to cover the entire cost of the bill. Then, use the object over and over again, as the repo man is repossessing it. The repo man will usually stand still at first and wait for you to finish. Just use the object again and he'll come grab it.
