Thinking of buying in NY. Have been advised that best option is to get a % of cost by way of a Mortgage in NY and to finance rest from equity here in Irl. Told that thats the best way for tax purposes also ??? I can finance full amount from equity if need be. Confused on how best to proceed. US mortgage rates are 6%+ at present & property prices appear to have dropped recently. Mortgage houses here won't do security on a US property either. Anyone any advice.
