If you are shooting only Real Estate the answer is what you already have, D7000. You will not see any advantage in upgrading to the D600. The quality from the D600 is only apparent if you want large wall hanging images. You are already downsizing the images you don't need more megapixels.
I have used the crop lenses on my D600. No advantage, the FF will crop the image in camera. So, you get the same image as if shot with the D7000.
Does the D600 not have the other image areas that the D800 has; i.e. 1.2 crop and 8x10?
In any case the suggestion isn't complete. Even in FX mode DX zoom lenses won't show the vignetting over some of their range in FX mode. For example my 10-24 doesn't show it above 18 mm...which is perfect for an FX anyway.
