I think you are doing the right thing by studying the neighborhoods and identifying houses that might stand out. 

I'm wanting one to filter through county land records, identify owners, perform background check to identify any types of contact, then organize that into a excel spreadsheet and return it to me.

Other options might be finding a partner who wants to develop the land (if that is possible) and building a regular home to sell or rent when complete.

Most developers I know are building closer to $400/square foot. 

So an exchange of building into land would be fine as long as his intent was to hold that land as an investment and not to develop and sell lots immediately.I think your idea is a very good one. 

From the day he sells to you he has 45 more days to identify his potential replacements. 

Just curious on how someone that wants to focus on mid and high-rise condo developments can start?

Identify property2. 

I will say that there is a lot of development in the works around these areas that should help improve property values.Stratford Estates/Ruskin Heights and Marlborough are all further south. 

After several months of not being able to identify the specific mold source they claimed was bothering them we released them from the lease and invasively tested/abated throughout the house before resenting.
