rezonning and best use analysis

[Derek Clark]

I am currently under contract on a piece of land that is zoned residential with a small single family home and 2+acres. The location is surrounded by office buildings and new development for retail and highway business zoned parcels. I would want to rezone the property for commercial use after closing given the surrounding areas already being commercial. My concern is there is a church next door and a small grave yard is adjacent to the property but you really cant see the grave yard from the property itself or the road due to trees and the fact the grave yard sits back off the road behind the church. 

My question is should I be concerned at all about the grave yard so close and will that have an impact on rezoning or the types of businesses that would want to lease out the land?

Also, what advice can you give to determine the highest and best use for the property?

thanks for your help!
