Couldn't have put it better, to finance this out of a remortgage sounds pretty dodgy, fair enough if you have the readies. This is generally what the big guns of the trading world do but they know their stuff, maybe stick the money in a pension fund, more property or multi ISA's.
Thanks, but makes no sense as it based on remortgage money, there is no way a pension fund is going to generate a percentage to even cover the mortgage interest as they are low risk.
