Bbbface's comment doesn't seem rude or out of order, just disagrees with the majority. It does seem the way now to be scathing of people who have a different opinion. I agree they should have paid the money back out of SiL's payout, but paying off a lump sum of their mortgage seems a sensible use of the money to take the pressure off in case he doesn't get a job for a while, particularly as they will have other payments. The rental from the flat should help for a while too but I don't really understand the comment about the market being poor, so perhaps they see the flat as insurance too. After all, they are not claiming benefits. Maybe the new flat screen TV has prompted you to ask for the money back, as it is an unnecessary item, although they can be fairly inexpensive. It was kind of you to offer the money for childcare but surely having both parents at home is an ideal opportunity to save some money and see more of DC? Childcare can also be a luxury item. Perhaps that's why they thought you were not in a hurry to be repaid. Of course they would prefer to pay you when SiL does get a job, and they feel on a more secure financial footing, and perhaps that is what they assumed. Also lending money until July and asking for it back in August is a bit short notice. As it wasn't clarified don't be too hard on them. I agree with other posters never lend what you can't afford to lose, and also don't rush to offer money until you're clear what their priorities are, but also congratulations for keeping good relations with your DD, which is worth so much more.
