Jbck, ours is not an endowment. I mean that interest is taken from our account.
I'm not sure if you're sure how they work, and don't want to sound condescending, but imagine it as a very large overdraft. Eg if our mortgage was £70k, we had savings in another account of £5k, we got it all up and running, our total morgage in this account would be £65k, overdrawn IYSWIM -as I say imagine it as a huge od. It runs as a current account, so our wages, child benefit etc all get paid in, our counsil tax, phone bills etc all come out as direct debits, and the credit card payment comes off each month too. As a normal mortgage payment of £500 would probably be made up of £400 interest on what is still owed and £100 of capital, the one account works similarly, in that they need to chrge interest on what we still owe, as I said that is calculated daily (that's why everything goes on cc so it "floats" for the best part of a month before it has to be paid) and interest is paid.
We don't make a payment as such, but if you imagine that we did have a mortgage of the £65 mentioned, we would have set our limit as perhaps £85 as a buffer- (remember all your savings go in here, so you have nothing if you need to buy a new car, carpets etc, the things your savings would normally be hanging around for), well each month this limit reduces, so that at the end of the 25yr term it will have come to zero, therefore if you are overdrawn to your limit (ie not using the one account as it could be) all the time, it will have been reduceing, therefore paying your mortgage off. The idea, like huge overdraft, would be to get it paid off as soon as possiblr, bringing your balance closer to zero as quickly as possible. The benefit is- where you may be getting say, 1 or 2% interest on your savings, but paying maybe 5 or 6% on your interest, if you can have them both in the same account but not have committed to using up all your savings and frrling a bit insecure, you pay interest on as little as possible, IYSWIM.
Not explained very weel, I could do with drawing a wee chart! HTH anyway!
