In a modest scenario the property appreciates by 10%. So roughly at the end of 7 years the value is doubled. But then a 7 year old property will never fetch the price of a brand new property.
Also one must remember that if the property in question is the only property one will never sell it unless in extreme and dire conditions. Hence the value is on paper.
But the feeling of having a self owned property is priceless, the security unimaginable.
