Since you say the house you found that you want:
- is not available for sale
- does not have the land that you would like
It sounds to me like you are still in the hunting stage.
Just enjoy the looking. Find a realtor that will only take you to view homes that are exactly what you want (the must-have features all align).
Have you searched Zillow.com? You probably have, but at least on Zillow you can get a good idea of a property before you have to trudge out to physically check them out.
In the interim, from the view out your window, I doubt you'll be sad that you are where you are whilst you look for the ultimate place.
