DRNorm,
I suggest that you read the post at this link:
Costs of Buying a Home in the DR
As for banks outside the DR loaning for DR property purchases, I seriously doubt that you'll find one unless you're a major millionaire with a long relationship with Citibank Private Banking in NYC, and even then, I bet that they would actually work the loan through their DR office rather than from NYC. Most banks like mortgages where they can at least get their hands on the property if the loan recipient defaults -- this would be too cumbersome, time-consuming, expensive a process for them in any foreign country, more so than most with the DR. Secondly, banks like to lend for properties with clear title, which is a chronic problem in the DR (just research the DR1 archives on this issue, you'll see!).
Regards,
Keith
