I rent an ex-coucil house in SE London. It takes around 45 minutes to get into the centre. The local drug-dealers hang out next to the house, there is graffiti on the walls, and it is next to one of the busiest roads in London. There have been multiple murders on the estate since I moved in. It is in the 96 percentile for air pollution. It is apparently worth six hundred and fifty thousand pounds.

Assuming a £100K bung from mum and dad for the deposit, a 25 year repayment mortgage at 5%, and further assuming you spent 50% of your income on the mortgage, you would require an income of £122K to afford it. That would put you firmly in the top 1% of earners in the UK.

Despite your high income, and paying £45K/year tax, you would live in one of the most deprived parts of the country and your local hospitals and schools would be in special measures.
