Yes, there's quite a lot of knotweed locally. Loads along the Wandle, and I've seen it in a Balham front garden! There is a professional-strength chemical (? concentrated glyphosate) to get rid of it, and it shouldn't be expensive to have someone come in and spray, (probably more than once), although there are some rip-offs, so get quotes and check that they know what they're doing.
Mortgages can be a problem if there is knotweed in the neighbouring garden. The surveyor who came to our house on behalf of Santander spent some time peering into next door to check they didn't have any before he would OK the mortgage.
