Interest rates are in the region of 8-10% and the mortgage term ranges from 15 to 30 years. I have looked into the mortgages myself and the rates work out to be roughly the same when you factor in the initial costs of borrowing the funds. Be careful with the flexibility aspect of the loan you take on board. Make sure that you are allowed to pay off lump sums at anytime during the term without being charged a penalty and make sure that this is contained in your paperwork. This is essential especially if you are condsidering a 99 year lease property and you may need to sell early to recoup your profits. If your intention is to sell, than make sure you sell with plenty of lease period remaining as the new buyer will not be able to secure a mortgage on a property with a short term lease. Check out the rules before you commit. Good luck
