Cobham Life May 2010 Japanese knotweed

Cobham Life in May 2010 reports on "Rampant weed blocks mortgage lending". Japanese knotweed is a major problem due to its voracious capacity to spread and its ability to cause damage to property. However, to refuse a mortgage simply because some knotweed is present on the land seems to be a complete over-reaction. Despite reports to the contrary, it is possible to completely remove the plant - we wouldn't offer 20 year guarantees it we had any doubts. You need to act fast to prevent its spread, to protect the value of your property and to avoid potential disputes and litigation with your neighbours.
