Thanks Katiealice. I understand all the implications and my view is the same as yours. Its just that when I expressed them on AAM, there were a number of posts that disagreed with me. I began to question my own understanding.
With regard to de-registering, it was a hypothetical question (no intention of doing so). Again some people said that it was impossible to de-register, if , for some reason, you needed to sell the property quickly. Glad you were able to clarify it for me.
On-line, I am able to see what VAT rebate I received and what I have paid to date. Call it a balance sheet.
