Example if I want to buy a 1 plus acre parcel on a corner for commercial and the seller wants a premium I need to know I can put a pharmacy on it for example like a Walgreens and get a forward commitment for the lease before closing.

Flippers have a reputation of cutting corners and doing things like sweep under the rug.

I am planning to go there sometime soon once i corner down on few properties.

Feb is right around the corner though, so I suspect I will have to initiate this process once more. 

Sharpe corners are inefficient. 

I would not respond to those who ask you to do deals with them on line.. just slow down and take it easy out of the gate .. no rush deals are like street cars there is always another one on the next corner.

If they're aware of a particular problem, they must disclose when cornered on it unless they basically "plead the 5th," in which case it is your responsibility as a buyer to perform your satisfactory DD.

Do not cut any corners to make something look better on paper.  

The answer is it depends... if the property is on the corner of two main streets then it's value could potentially huge.

Use the "4 corner rule" - meaning - refer to the lease.
