the bank she chooses might go under and, again, they lose the lot.
8k would be covered if the bank went under.
It's fairly clear the OP and her dh dont have cash to spare
This isnt their cash. I very much doubt the OP and her dh can do all they say and save up to oay the kids back.
They need to save a minimum of £150 per month to have it back in 14 years.
She said they will be £300 a month better off. So £150 to savings and £150 for upkeep of the house, family days out, repairs, buildings insurance and all the other stuff.
Doesnt really equate to them being so much better off.
That's the problem. If they could borrow it, legally, ensuring the kids when they are older were fully aware and know the could definitely pay it back, there woildnt be such a huge issue.
But the fact is, is that money is tight anyway and a small thing could make it so the cant afford it. Her dh having his hours reduced for example.
And what are the consquences if they dont pay the money back. What if one child really needs the 8k and wants them to sell. Another one doesnt want their parents kicking out of their home. It's got potential to really cause a family to break up over.
Plus the fact that it's their money, no one should be risking someone else's money.
