I rented to a young couple a few years ago and they ended up being evicted owing me $600. Now, several years down the road that $600 is $1200 with the filing and sheriff costs, the attorney fees written into the lease, and the interest. They have had a child and are finally straightening themselves out into responsible adults. they decided to move into an apartment complex and two days prior to move in, the management office told them my judgment showed up and they need to take care of it or they can't move in. Luckily, it's tax return season. They called me thinking they can pay the original $600 only. I took their $600, gave them the letter they need to move in and had them sign an agreement stating they will pay me $25 a month on the balance. I told them if they pay the $25 a month and never miss one payment by one day I'll forgive the interest... we shall see if they make it as they've only had to make one $25 payment so far.
Point of this is, once you have the judgment, you are totally in the drivers seat when they come back later... you don't have to give up your position but you can bargain.
