History of our house

Today was an exciting day. A big bundle arrived through the post containing the deeds to our house. After nearly 25 years we've finally paid off the mortgage- hurray! Apparently deeds aren't really essential these days as all the records are kept electronically which in some ways is a shame. It was fascinating to look through the bundle and basically see the history of our house. It was built in 1897 which is about what we thought and originally had a different number (which is why I'd never been able to find it on the 1901 census).
The first buyer was a Mrs Southam who bought it on a 999 year lease for £213 and sold it on the next year to an Ebenezer Bishop for £236.In 1902 Alfred Howard bought it and in 1910 a Mr Tidswell. In 1918 just after the war it was valued at £350 andFrank King and his wife Beatrice moved in. They stayed for 26 years till Frank died in 1942 and his widow sold the house to a butcher called William Green for £950 in 1944. In 1947 Charles Fitt an insurance manager bought it for £1500 and a year later sold it for £1750 to Garnet Lucket Humphries a teacher from Bexhill. The Humphries were there for 23 years, then it went in 1971 to Mr and Mrs S for £5750.They also got the lease changed to freehold. 10 years later inflation had definitely kicked in. The Rs bought it for £26500 in 1981 and we bought it in 1983 for £29,500. It's currently valued at about £300k.
I tried plotting the costs on a chart and it was really impossible to find any kind of sensible scale for the inflation of the last 30 years. I remember at university living comfortably on £5 a week (not including rent) and I thought somebody who earned £100 a week was incredibly wealthy!
