Call all the FSBO's in your area and find out what the asking prices are to further flesh out your market data.

If your dead set on the course I wouldnt pay more than 2 to 5 k at the most.

Selling in the dead of winter (in UT) is not ideal.

If the owner is dead, I would consider just taking the property over.

All you've done iw pay for all of your negative cash flow upfront.What's worse, is your cash (the $1,025,000) is now dead.  

Im going to bring this thing back from the dead here...   

I wouldnt be caught dead walking the area @ NIGHT.  

Anyone have any thoughts on how to get more information on tower leasing or is it a dead end?

That is a serious negative cash flow investment property.If you can finance the property to the maximum amount and achieve positive cash flow plus invest the cash in other properties it will be worth holding otherwise you should sell immediately and reinvest elsewhere.As a investor you need to understand that leaving cash dead and buried in a income property is a poor business decision.

@Albert D.In regards of reusing the parking lot materials to construct the concrete foundation of your future building, it is likely that you need additional material and other separation layers (such as base course) to support the loads of the building (depends on how many stories, dead loads, live loads, snow load, etc.) to build-up the foundation concrete lab or other type of foundation.
