GM that is happening all over Britain. Not just in your area.
Its happening in some places Mick. Its in the constituency where I live, but not in my 'area' as such. The reason lots of recent immigrants have moved there (and other similar places) is because there are available properties for rent from private landlords who perhaps aren't too scrupulous in their lettings.
Terraced streets were once home to ordinary, local families, who started earning a bit more, then decided they wanted something different. Ex council properties, which originally were bought cheaply by tenants, were sold for a profit and the owners moved on. Those without the ability to choose are left in areas that may have changed beyond recognition.
Its not just about immigrants though. The 1977 Housing Act saw the end of council houses being rented to people in different types of jobs and professions. The whole idea in the early days was to have mixed communities, teachers lived next door to factory workers, bus drivers next to policemen etc. Back in the day couples had to be married, the family breadwinner (usually the male) had to have a job, but none of those rules around respectability helped the most in need.
The then Labour Government changed policy from giving council homes to local people if they waited long enough, to assessing need. Thats the first change to the pattern, then Right to Buy changed things again. The best houses in the nicest areas were being sold, meaning that the homeless, the dysfunctional families, the unemployed were becoming concentrated on the less desirable estates. Some of the original tenants who couldn't afford to buy or move suffered from the changes, and we started hearing terms like 'sink estates'. Local shops, doctors surgeries disappeared, and schools struggled to cope with behavioural issues.
There were serious problems long before the EU opened the borders. However, enormous numbers of unskilled immigrants moving to areas with concentrations of crime, poverty, unemployment, gangs etc has made the situation even worse.
But in some places, we are seeing the opposite. Relatively affluent areas are in demand from people of all ethnicities, crime rates are low, educational standards high, shops and businesses flourishing. Nothing to do with people's colour, their ethnicity, or where they came from: all to do with their standards and expectations of behaviour. And of course, money.
I think about the people on this forum and what they've said about their earlier lives, and how they've moved on. I can think of several examples, myself included. Although we aren't affluent, we no longer live in the run down rented house with the outside toilet that we had in the early 70s. Mike Rolls has mentioned his widowed mother having a struggle. With the possible exception of Brian, who inherited a house, and one or two others, I bet the majority here have moved onwards and upwards, or their children have.
Sorry for the long post.
