Students are nice little earners, say property experts. Although parents usually expect to lose a small fortune when their children go to university, many have been doing rather nicely out of these years of study.
However, those buying property in the North and North-East seem not to be faring quite as well as their southern counterparts.
Research from Landlord Mortgages, a leading buy-to-let broker, say that parents of children just completing three year degree courses made a profit of almost £32,000 - if parents bought a place in Edinburgh back in 2004.
That figure includes a capital gain of £28,939, as Edinburgh's average property price now tops £311,000, plus £2,688 saved on rental payments.
However there were much smaller rises for parents in Nottingham, Manchester and Durham, which took the lowest place in the league table with a profit of £6,465.
Other big risers over three years were Central London (profit £29,346); St Andrews, with its Royal connections through Prince William and former girlfriend Kate Middleton, (£22,990) and Bath (£19,935).
Lee Grandin, Landlord Mortgages managing director, said: "With stiff competition for rented accommodation in university towns, investors have a captive audience, so this type of buy-to-let can be highly profitable."
But the bumper figures reflect buoyant years in the housing market - with no guarantee of a repeat between now and 2010.
With centres like Bath indicating an average property price of more than £200,000, parents must be sure that they can service a large mortgage until children have completed their studies.
