Am a regular but have namechanged as my other posts would make me quite identifiable while the below is quite sensitive.
In a nutshell, AIBU to want to stay out of the financial arrangements for buying BIL a new house? Background is that BIL has a house, but has jacked in previous job and taken a new one about 2 hours' drive from where his existing house is, but near where PILs live. New job has started and he has moved in with the PILs. Plan is for him to buy a new house in the new location, but the existing house is not yet sold and realistically it will be three months or more before that happens. BIL is not the easiest person to live with (massive understatement), so current living arrangements are not sustainable.
MIL has seen a house that she considers perfect for BIL and is very keen to buy it, but, the PILs being elderly, it is difficult for them to raise a mortgage. BIL will have some money once his current house sells, but there is no saying when or how much that will be. BIL and PILs are not good at communicating, so at the moment there is a lot of stress and they are basically no longer talking to each other.
DH would like to avoid his family "imploding" and so would like to suggest that we take on the mortgage for BIL, on the understanding that BIL or PILs finance the repayments and that we fall out of the arrangements in 2-3 years' time.
I am very wary of all this as BIL has a very checquered financial history and I can see that we would be stuck with a mortgage on an unsaleable property in a part of the country not many people want to live in. Plus, BIL does not look after anything he owns, so any investment would be likely to depreciate rather than at least hold its value.
Also, if DH and I take on a second mortgage for this, it will mean we cannot move house (which we might want to do) and potentially could even affect our ability to provide for our children in the way in which we would like (and have been working hard for). However, DH does not see how we can avoid offering to help, given we both have good jobs and given that, one way or the other, we will have to provide for BIL (and/or PILs) when this all goes wrong.
I am also annoyed/concerned that nobody is talking openly to anyone about this, so, for example, nobody has had the courage to suggest to BIL that he cuts his coat according to his cloth (you know, not trying to buy a multi-bedroom house that he cannot afford and frankly does not need, given he is on his own) or that, for example, he rents somewhere while waiting for the existing house to sell. I can see that this would continue going forward.
AIBU to want to stay out of it all? And if IANBU, any suggestions as to how to achieve this diplomatically?
