Yes im on interest only, but I dont think it would be that silly, Im sure what Stu is getting at is I could afford 728 before then I probably still can now (in fact my income has gone up about 8K a year since then so potentially I could afford a bit more) so by paying it off, at least when rates go back up, even if they went past where they were before, Id know my repayments were still going to stay affordable.

Assuming the rates stay down, Im planning on a 20ft * 10ft conservatory onto the back of the house with the profit im making on it, that way I'll pay no tax I believe, although I'll have to look into that to make sure that's the case.

If I get it built in March-May 2010 with staged payments, I can write 4K or so off against each of the two tax years, and that sorts me out for not paying tax until the following (2011-2012) tax year.

Assuming im correct that this would be a valid expense to offset against the earnings. Havent checked yet, will need to speak to an accountant.
