Can someone advise me on this remortgage situation?

[fedupandfifty]

I've just come to the end of my mortgage term on a Woolwich Offset mortgage.

I've been offered a remortgage as a btl on the house. There were so many hoops to jump through that, by the time I had everything in place, the mortgage offer had run out.

The company I'm hoping to mortgage with tried to redo the offer, but when they looked at my credit score, the score had gone up due to the mortgage debt from my old mortgage appearing as a debt.

So, the Woolwich want their money back, but the remortgage can't go ahead as the new mortgage company now won't consider me as I'm now an increased risk.

I'm not sure I'm making sense.. Has this happened to anyone else?

If so, any advice?
