Japanese knotweed - is it as bad of a nightmare as people say it is?

How long do you have to declare Japanese knotweed when selling a house (after being treated) or is it one of those that have to be declared forever?

The TA6 form just asks : “Is the property affected by Japanese Knotweed?” to which a tick box answer is either Yes, No, or Not Known.

In this context it’s asking if there is knotweed within 3 meters of the boundary and the guidance is:
If you are unsure that Japanese knotweed exists above or below ground or whether it has previously
been managed on the property, please indicate this as 'Not known'. If 'No' is chosen as an answer, the seller must be certain that no rhizome (root) is present in the ground of the property, or within 3 metres of the property boundary even if there are no visible signs above ground.

TA6 is an English & Welsh thing. There is no standard question about Japanese Knotweed in the property questionnaire in Scottish Home Reports.

Whoops, I forgot the OP was in Scotland.

Would it be fair to say that hardly anyone could answer "no" unless they dig up all the ground to check. They would have to answer "not known".

I’ve checked online and it mentions it could devalue a house by 5-15%. Anyone know from experience how much I should ask for a reduction?

user1977

If there's a treatment plan in place and it's already taken account of in the Home Report valuation, why would it merit any reduction?

There is the fear of future saleability when I go to sell the flat. Also the stigma as a commenter mentioned above with buyers being put off by the mention of Japanese knotweed. If I need to give a discount I’d hope the seller would do the same - or am I asking for too much with a reduction that it may cause in the future with selling? 

user1977

Where's your evidence that JK deters buyers where there's a treatment plan in place and they in any event only have a 3% share of the costs of any further work needed?

I was talking to my friends and family about the flat and they said to avoid even when I said there is a treatment plan in place. Looking online a lot of people are saying they’d avoid unless there was a reduction so I was basing it from my friends and family opinion along with checking online out.
