We have very little equity in our home, but reasonable pension pots.
I earn a decent income, probably enough for me to stay on the mortgage and still be able to get another mortgage to modestly house myself. My ex-wife-to-be on the other hand will not be able to get a large enough mortgage to buy a house big enough to house herself and the children - even if she takes all the equity in the family home. In practice I'd like to have a small amount of the equity to get a 10% deposit on a house myself - or maybe only 5% now the government has backed that option.
My thoughts are that we could buy a house for her in joint names now (which she would either 100% own, or I would have a very small, say 5% stake in if that is required legally), and I could pay half the mortgage for the next 13 years. She would then be old enough to take a lump sum out of her share of the pension pot, which would reduce the repayments down to a level which she could afford without my involvement, and I could come off the mortgage then. By that time all the children will have long flown the nest, and so if the pension pot has shrunk for any reason, or if she would prefer not to touch it for this reason, she could downsize instead.
Does anyone have any experience of doing anything like this?
