"Also, the valuer acting for the purchasers mortgage lender will have to include a value for the contents (usually quite small as they are considered 2nd hand goods) but the bank will not lend for this portion of the sale price.
i.e. if the sale price is 200,000 and the bank is giving a 90% mortgage, the valuer values the contents at, say, 5,000, then the bank will only lend 195,000 x 90%."
Re: the above, I can't speak for every lender, especially in today's market, but I bought my house fully furnished and I was given 92% mortgage and the cost of contents was not considered in any way, shape or form.
As to OPs original question, I would imagine if the contents are included as part of the sale (as in my case), I can't see that there would be tax implications.
