I agree - don't accept partial payments. Normally, when we return that first payment back, they come right in and pay it in full with no issues. I think the residents sometimes see how long they can get away with it but when you return their money, that triggers something. It also gives grounds to evict and it sounds silly to evict on that amount but again, usually the threat of possible eviction usually gets them to understand the seriousness and they pay the full balance. I literally had a resident comment "I'm not getting evicted over a $100" and she came right in and paid it before I even filed. I'd challenge your manager to ask what's more important - to waste your admin time, money and energy to keep following up with all of these smaller amounts (which do add up to a lot of money if you have several residents like this) or clean it up in 1 swoop. I'm telling you, when you return their money and state because they didn't pay the full balance and they could now be evicted, they usually clean up the account right away. Good luck!
