Agreed that won't make you rich in London but you can very easily buy a house outside of London or a 1-bed in London. I have friends who are on less than that and are buying in decent zone 2/3 areas. Mortgages are actually pretty cheap if you can save up the 10% deposit and live with a 10/15 min walk to a station.

but you're one child or a 1% increase in interest rates away from being in trouble

You won't get a mortgage if you're that close to struggling. Lenders will generally stress-test affordability at between 5%-6.5%
