Andrew, I'm also an investor. I love that open house idea for finding tenants. I hope you don't mind me borrowing that golden nugget. :)
Jason, Keith is correct: houses are selling in your area. Andrew is also correct that renting doesn't have to be a losing proposition; you'd have to screen your potential tenants like a lender would screen you before lending to you--after all a lease is for all intents and purposes basically another form of loan. Combined with effective property management, this could be an option for you.
Also, since your pool of buyers has shrunk, and since many buyers would have to qualify for a jumbo loan (which is harder to do today), you might find that you'll get a lot more interest (and offers) if you were to offer seller financing.
