but less than buying a house in the first place. Property is more volatile than a tracker fund, has lower average returns, ongoing costs, and is less accessible.
I was intrigued by this comment so though I would dig a little.
The FTSE return is a little under the 7% I mentioned, but was good enough for that purpose. As I said it keeps throwing up 7% on many metrics, so it seems a good number to use, the actual is a little under however.
When you consider house prices matching the same period the FTSE100 has been about your actually right (I would have guessed not actually), the average UK house price inflation over the same period is around 6.1%. So not significantly different to the just sub 7% of the FTSE.
Looking more recently I suspect house prices may outperform, they haven't fallen really recently where as of course the FTSE has. So time period would be significant in this comparison.
However I don't think unless your a serious investor (talking multiple properties type level of investment) its a fair comparison. People buying houses and looking to lower the term of a mortgage aren't typically buying other properties to act as an investment to do so
Your 100% right on the additional costs. The costs to dip in and out on a tracker are negligible, and also suffer minor upkeep costs vs a house.
Not only that you can also spread and divide so you can hedge your gains/losses a bit as you don't have to go all in or all out.
Volatility though I have to disagree, there have been swings of practically 50% on the FTSE (eg its hit highs of £6.6k then lows sometime afterwards of £3.6k more than once). However this is actually why I think its better than property, the point of a side investment in order to pay down some mortgage at a later indeterminate date is to be able to time and play the market a little. As discussed its easy to dip in and out, with low cost. That market volatility is what you want in order to play it.
So somewhere around the 50-60% of they way through the mortgage term you start to look at liquidating the investment (fully or partially again splitting a real option), pay down the outstanding capital and then switch to a simple overpayment regime, since by then the compounding of the investments or mortgage interest is becoming less and less impactful.
Of course you can always go far deeper, even beyond term if the mortgage payments are easily met and you want to max the investment gains.
Thanks for your comment, that sent me off on an interesting path.
