Thanks for your response.
I have looked back through my records: the property was put on the market on 15.11.2014.
I also emailed my accountant for advice about this same issue I discussed with you on 31 Jan 2015 - but I did not receive a response. We had not received an offer on the property at this stage.
To help push through the sale , we reduced the price of the property from 300,000 to £280,000 in early Feb 2015 - subsequently receiving an offer.
Do these dates help my case in any way , or do you feel HMRC would still take a jaundiced view as I only sought advice from my accountant AFTER the property had been put on the market (though before we had received an offer?).
Understood. Thanks again for your advice.
