Revealed -- the country's cheapest houses

LONDON (Reuters) - The cheapest street in England and Wales is Tower Green in Middlesbrough, where houses sell for an average of just 21,290 pounds, according to a survey.

The cheapest houses on the market are all in the north of England, where properties can still be found for less than 30,000 pounds, www.mouseprice.com said.

While the average house price in England now stands at more than 200,000 pounds, the top 20 streets in the survey are all in the north, based on an analysis of Land Registry data since April 2000.

Other pockets of cheap houses available for less than 30,000 pounds are in the northwest, Yorkshire or Humberside.

Prices in the north are sometimes depressed by "right to buy" sales and regeneration or demolition plans in the street, the property information provider said.

A concentration of very cheap properties is in Nelson and Burnley, near Blackburn in Lancashire, where there has been widespread compulsory purchase and demolition of very old houses as part of government-inspired regeneration plans.

But other cheap locations around the country do not quite conform to common preconceptions of what a cheap area looks like.

In Tower Green in Middlesbrough the cheapest properties are modern but have been blighted by neglected and sometimes vandalised neighbouring council-owned properties.

In eastern England, Clacton-on-Sea provides a clutch of properties which have sold for just over 50,000 pounds.  Continued...
