Fewer than four per cent of typical family homes in south Northamptonshire are affordable to people trying to buy their first home, according to new research by Shelter.
The figures show out of 588 suitable homes with two or more bedrooms, only 20 classed as affordable.
Elsewhere in the county, there were 548 homes in Daventry and 44, or eight percent, were affordable. In Northampton the picture was somewhat different with 295 affordable homes out of 849, or 34.7 percent.
Shelter looked at the asking prices for all properties for sale in the East Midlands on a single day and compared them with the mortgage that families, couples and single people on average wages could afford as first time buyers.
A spokesman for Shelter said: “Unless the government tackles the root cause of our housing crisis – the desperate shortage of affordable homes - things are only going to get worse. This will not only affect future generations hoping for a stable home, but also the thousands of families already facing an everyday struggle to pay their rent or mortgage.
Shelter chief executive, Campbell Robb, said: “When the number of affordable properties in an entire town is so small, it’s not difficult to see why a stable home of their own is quickly becoming a distant dream for the next generation.
“It’s right that young people who aspire to own their own home should work hard and save each month, but with such a pitiful number of affordable homes on offer - even with a generous 20% deposit – our housing shortage is holding them back.
“Unless we build the affordable homes we desperately need, house prices will continue to rise and as a result more people will be forced to live at home with their parents into their thirties, or move into the expensive and unstable private rental market.
“Young people are working hard and doing their bit. Now the government has to meet people halfway and increase the supply of affordable homes - not the supply of credit - or the prospect of a home of their own will slip even further out of reach for future generations.”
