I have located a property in Antioch, TN that has been fire damage and is now just land and a lot needs a total rebuild.

I need to pull the trigger this fall on an expensive rebuilding of the parapets on one place, they're falling in.

The property could be in perfectly livable condition but you may just want to update the paint or a toilet or something small, or you could tear down the property and rebuild it (must keep foundation). 

Where is the house, as that has a huge impact on what the costs to rebuild will be. 

My concern is that all the properties we saw walking around were either a) freshly rehabbed and look like they would be priced at a premium, as well as being SFH, OR b) literally, completely falling apart (windows busted, roofs half off, walls open to the outside) and would require a gut or even more hardcore rehab and rebuild to make habitable.

Tearing down a small house and rebuild.

@Sherwin Vargas All I read was I am rebuilding my credit but I want to finance a new car...

The lot has grandfathered zoning to rebuild another two unit structure within one year of demo.

Especially for lower price point houses, I know I will never truly rebuild, and I know that for any partial damage I will have to bring in the adjuster anyways... 

Yes,  I  am working on rebuilding my credit but even that takes money and time.
