I've moved into my new house last year and did not sell my existing home mainly due to the fact that I had no mortgage on it. I did up the old house and rented it in March of this year. I was looking at buying a property in France and was wondering could I get an interest only mortgage on my old house to purchase in France? This would make sense if I could write off the Interest against my rental income before I made a return to revenue next year. Thanks in Advance.
