Sell or rent current house when moving to a new area?

[John Hatch]

Help me do the math here.
Background:
My wife and I life in Palm Harbor, FL. The last two years real estate has been very hot here. We want to move to Aiken, SC to semi-retire and invest in real estate. For family reasons we were unable to do that until now.
Our house is on the market at a reasonable price. However, there are lots of houses on the market and few buyers. So we're weighing the options if the house doesn't sell.
Facts to consider
1. Our monthly expenses on the house are around $2,700.
2. Monthly rental would probably be $2,500 to maybe $2,800.
3. We can afford to buy a condo or a house in Aiken without selling this one.
4. We have a lot of equity in our current house.
5. We really don't want to stick around another year in Palm Harbor.
6. It doesn't look like "the bubble is about to burst" in terms of pricing here but houses are taking much longer to sell.
7. Our current house is very attractively decorated but has some elements that need updating (tile floors, bathrooms). We've done all the inexpensive fixups so the next step would be major tiling, gutting bathrooms, etc.
