BoS, I know that dilemma. years ago we did a lot of paying off debt - in fact paid off all the debt on our two buy to let flats when other people went out for meals, took a maternity leave, worked part time etc etc and obviously got work promotions and pay rises too and did 2nd and 3rd weekend jobs. And that saved a lot of interest - rates were 12%, 8%. I found a 1983 diary and I was moving some savings from a 7% interest rate savings account to 8%. (Those were the days although that was not so long agter 60% inflation over 3 years in the 1970s which cruficifed your savings - it was like Zimbabwe almost better to buy a TV before they went up double in price with rampant inflation).
Then roll forward to now even from the 6% I was paying on the mortgage in about 2005 I think it was, and if you are paying under 3% mortgage interest it feels hard to justify paying off debt. However I still recommend it even if people think they can guess the next Ocado and make a killing on their savings on the stock market instead as over the 30 years you might have a mortgage interest rates can and do rise, Of course for many of us for lots of year we hardly have enough money to pay the gas bill and mortgage never mind over pay on a mortgage. It is a very lucky choice to have for those who have it.
TheFatkins has it right - it will be personal psychology too. I have never liked debt and even if it means I have a worse life now that is fine as having less money but less debt actually for me means a happier feeling although I was paying a mortgage for about 30 years so I have certainly done my time paying mortgages.
London prices have gone down 2.5% in the last year the survey today says - see I think in City AM set out by borough but that hides the fact some over priced boroughs have seen bigger falls particularly to over inflated asking prices. Wales has seen an increase because it is about to increase stamp duty under its new land tax massively for the reasonably well off which is not going to make us want to flock to Wales I suspect so I hope they know what they are doing out there.
