Is UK house price spiral connected to debt based monetary system? 
There are a few factors at work here, supply and demand being the main one. The Office for National Statistics has some good information: http://visual.ons.gov.uk/uk-perspectives-housing-and-home-ownership-in-the-uk/ Supply has historically struggled to compete with demand in the UK and this situation has been exacerpated since the 1980s when Margaret Thatcher was Prime Minister.  She set up a variety of schemes to encourage people to own their own home, such as tax relief (MIRAS) and since then home ownership in the UK has increased dramatically. The then conservative government also set up the "right to buy" scheme (in 1980) that allowed council tenants to purchase their council houses at a discounted rate.  The effect of this was to increase the number of home owners whilst reducing the amount of housing available for councils to rent to new tenants.  Anecdotal evidence (I can't find a documented source to back this up) suggests that councils did not build sufficient new homes to replace those purchased by their ex-tenants. The population of the UK has also increased, by around 10 million since 1980 (around 20%) and this has pushed up demand for housing.  House building in the UK has not kept pace with these factors that has led to a shortage of supply that has pushed up prices. http://www.ons.gov.uk/ons/rel/pop-estimate/population-estimates-for-uk--england-and-wales--scotland-and-northern-ireland/2013/sty-population-changes.html There's another factor at play here as well.  If you go back to the 1970s around 53% of women would go out to work but in 2013 this figure increased to 67% as it became more common for households to have double incomes.  This extra supply of cash also pushed up house prices. http://www.ons.gov.uk/ons/dcp171776_328352.pdf Your question regards a debt based monetary system is not entirely clear, but there are limitations put onto how much money people can borrow that are potentially limiting how much house prices can rise by.  Today most lenders are more conservative in how much they will lend but this wasn't the case in the mid 2000s when house prices rose very quickly.   Lenders are more cautious today after the crash of the late 2000s, but things are begining to relax again and they are starting to lend more which could in turn lead to further house price rises in line with what was seen in the 2000s. Recessions have coincided with house prices falling back or at least being stable.  In the 1980s house prices trebled from 1980 to 1988 but then fell back a little as the recession hit, before starting to rise again in 1997.  This rise was sustained until 2008 during which time prices trebled again.  Based on this you could assume prices will treble again as we come out of the recession, as long as this is sustained for 8 years or so. However, as the potential for more households to become double income is reduced (high female employment already) and wages are unlikely to raise that quickly, this may not be realistic, unless the mortgage lenders become extremely lax, to the point of reckless! To answer your other question, about the affordability of housing, this will be based on the level of wages in the UK and how strict or lax the lenders are, also taking into effect the availability of housing for purchase.  If wages rise, house prices will rise, if lenders are willing to lend more money, house prices will rise and if demand continues to outrstip supply, prices will rise. None of the major UK political parties are likely to solve the problems of population growth and not enough houses being built so it is likely prices will rise but you could argue that they are not far off a peak based on current wages and lenders attitudes.  If the UK economy continues to recover from the recession, it is possible they will fuel another housing boom by lending ever increasing salary multiples as happened in the 2000s, unless there is government intervention, ie regulation of the lenders.
