We have spent so much time and effort improving this building and I hate to lose all that we have gained in the past several years to this person. 

The presidential center offers a rare chance to reinvigorate the economy of nearby communities and make improvements for the area’s infrastructure and parks.

I'm sure the nerbors appreciated your improvements. 

In 2014, Elgin completed the Central Business District Streetscape Improvement Project and the Riverside Drive Promenade.

But it added a touch of confidence that helped me talk to my first motivated seller.

So, I have confidence in that kind of deal, since I've done it. 

I suggest putting in at least 4 inches to cap your building and improve energy consumption, At the time of the tear off coordinate renting a blown insulation machine too and you can add insulation from the roof into the attic/crawl space above the ceiling level to avoid interior repairs.

It will need improvements to get a renter, but I'm not sure how much (or how little) I could get away with.

You normally do some renovation to the property to improve the value.

Real estate is transferred, and identified, by the Land legal description (along with all the improvements on it), so as long as the lot description is correct, it should be a simple correction.
