A year ago, few in the currency market would have predicted this stunning reversal in the flow of capital.

Despite being the nation that's likely to bear the largest economic and fiscal costs -- including a huge increase in its budget deficit and national debt -- from the global financial crisis, institutional investors are turning to the U.S. dollar in a flight-to-safety that economists say shows few signs of ending soon.

Investors flee to the dollar

That's right: you read correctly -- investors are turning to the dollar as a safe haven. Despite a decade of budget and trade deficits that drove the dollar to records lows. Despite an uncertain (at best) immediate economic outlook (the U.S. will be oh-so-fortunate to experience only a mild recession). Despite disagreement in the nation over the best way to pay for the many rescues / interventions needed to end the crisis. Despite the uncertainties presented by the upcoming U.S. Presidential / Congressional election. Despite its inadequate infrastructure and underdeveloped industrial base.

Despite all of the above, institutional investors abroad want: dollars. Money is flowing out of emerging markets and into the dollar -- so much that the major central banks may very well have to intervene repeatedly to support emerging market currencies to prevent further global financial system destabilization. Institutional investors are also flocking to Japan's yen, due to that country's relatively lower exposure to toxic assets.

Is there any more important rule in real estate than, "location, location, location"? In case you've been living under a rock, that's the answer to the question, "What are the three most important factors in buying a home?" The basic idea is that it's not the Sub-Zero fridge, the spacious deck, or the fancy faucets that dictate whether a home will hold its value. What matters most is where it's located.

USA Today proves the point yet again today with new findings from a Coldwell Banker survey. The survey looked at similar houses -- all with four bedrooms, 2 1/2 baths, a family room and a two car garage -- and compares how much they cost in 384 markets around the world.

The most affordable place in the U.S. is Minot, North Dakota, where a four-bedroom home lists for $132,000. The least? Beverly Hills, Calif, where the price tag is $1.8 million. Take the trends abroad and you can pay $1.8 million for that kind of house in Milan, Italy, or just $56,500 in Bogota, Columbia. The average sale price in the U.S. is $424,000 (you can parse all the data here).

What good does this information do you? Well, if you just paid $2 million for a split-level in Greenwich, Conn., and are worried you bought at the peak, this data may make you feel better. At least you bought in a premium location that will hopefully hold its value.

Better yet, if you are thinking of trading down, a handy tool at the Coldwell Banker site allows you to crunch this data and see how much a home comparable to your own would cost anywhere else in the country. For example, you can trade in that $2 million Greenwich home for a similar $278,000 house in Amarillo, Texas, should you one day decide to head to cattle country with plenty of free cash in hand.
