Further, OP hasn't said why her DH wants to do this or what the alternatives are. If OP says no, will the ILs seek a reverse mortgage instead in order to free up cash? If that happens, when ILs die, the current house goes to the bank, no inheritance for DH. Are ILs currently homeless, with no money for down payment? If OP says no, will DH suggest the ILs move in instead?
DH is an only child who apparently feels some filial obligations. It sounds like OP wishes that weren't so. But saying no to this idea won't make DH any less keen on helping his parents.
If you re-read the OP, you'll see that the IL's apparently have the 20% down payment, which begs the question as to why they can't get a mortgage on their own. I'm hard-pressed to come up with a scenario where this makes financial sense - I'm genuinely curious as to what you think one would be. From an inheritance stand point, it's a really bad idea. Hopefully op can come back and clarify her dh's thinking. I'm all for helping and supporting one's parents and IL's if necessary, but I can't begin to imagine a situation where this option makes sense.
