I'm 38 with no kids and my partner and I have fairly good jobs. My sister is 2 years younger than me with 5 kids and husband who can only find temporary work. They are yrying to sell their house and move into council accomodation but until they do have to pay rent and mortgage. Their house is for sale for £80k and their mortgage is for £55k. They also have a lot of debt and a bad credit record. They have borrowed from my sisters MIL but they are estranged now. Our parents are dead so I'm the only one she can turn to.
She sent me a message asking to borrow £4k so she can move into their new house 'comfortably'. It is not an inconsiderate sum for me. We are also in the process of moving house and our joint savings will be our deposit. We had a couple come round today for a second viewing for our current house and they said they seemed very keen.
I said that i couldn't afford £4k but perhaps £2k. She said she will pay me back when she sells the house. But now it looks like an offer on our house could be imminent and i will need the £2k myself. My DP would be really annoyed if i loaned the £2k (it would be out of my money) as I've told him how much i can pay for a deposit and this loan would take a large chunk of it especially as he knows I have also loaned money to them before a long time ago and never got it back.
I don't want my sister to get into a mess financially but i have my relationship with my DP to think about too. She has stopped talking to me before over a lot less but we are really close otherwise. I need some good advice on what to do?
