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.
