we have a v small house and two dc's. we really need to move. Our house is prob worth about £300k and our mortgage is £138,000. A fab semi detached house is on market, near to school etc that would be perfect for us and we would not need to move again. It is on market for £410. We would therefore need to borrow an additional £110k to get it which we cannot afford at the moment. Well i reckon we could but only if we get the extra £110k on an interest only basis. Our current mortgage is repayment. Would you take this risk or should we just stay put and be happy with our lot, until our finances improve?
