"Interest rates are low".
Know where else interest rates are low? Detroit. How about Gillette, WY? Probably low there, too.
Neither are locations any of us should be interested in investing in. Not right now. Low interest can be offered by banks to try to inspire people to take out loans - and why wouldn't they? Their options are to not lend any money, dry up and disappear - OR - to inherit property they don't want by way of foreclosure.
So, DUH - there will be low interest lending available.
What will come next? Probably some government promoted or subsidized housing/incentive programs. Spiffs from the county and the state to inspire purchases to keep moving through so the home values don't drop. If they do - reduced tax revenue all around. Drop in sales tax. Drop in property tax. Less government services. Less government employees.
When the decisions of one employer in the community could result in a $200,000 house being valued at $40,000 almost overnight - "low interest" is probably not enough to make a real estate purchase a sound investment.
