Entering Cost basis of flip (flop) house when I paid less than the valuation.

I bought a house to flip in 2014.  Things dragged on and I still own it.  I put part of the house in service as a rental in 2019 so I am adding the property for 2019.  The 2014 tax valuation of the land was $26,500 and of the building was $95,900.  I paid $22,800 for the entire thing.  Of course for that price the building was unlivable and in reality somewhat worthless.  I put $140,000 in it and $10,000 in refi costs partway through.  I entered the tax value of the land as $26,500 but what do I put for the value of the building?  Do I put $0 or the $95,900 town tax value or the $140,000 I put in it?  I am thinking the refi costs and cost to get it livable would be entered under assets and get depreciated.  Thank you for any help you can give me.
