You could certainly keep relisting it and if the market conditions change in the future to more favorable it may sell at the price you want. But there is no guarantee - only the most inexperienced buyers wouldn't check the past history and see that it's been for sale for a while. Which tells them immediately that you're asking more than the market value.

I'm in the if you want it to sell in the present market lower the price or add value camp (even by splitting the lot).
