Well the deal went South fast with none of the contractors being able to do the renovations for the estimated cost and no suitable tenant could be found which delayed the project that much more and added to the over all cost. As

For me I can troubleshoot furnace issues but if I have a tech come in and tell me the repair will cost a couple hundred bucks I'm replacing an older furnace o a more efficient model every time. 

The court just awards an actual cost as you are out $10 the award is $10.The HOA and COA's aren't regulated with the Move In/Out Fee and don't charge an actual cost amount. 

Their paint is thicker thus why it cost a little bit more.

I sold it two years after I bought it and vowed to never deal with a HOA again in my life.They're a pain, and they're an unknown future cost, as well as unknown future rules. 

Also included is interest lost due to that money not being in my bank (general interest i think they call it) My time being the most costly and rightfully applied to the cost as I am working for my company and I don't work for free.

A new gas stove usually runs just the $300 to $400 you stated, so teeing off the existing line, adding a shut off for the stove, and piping the stove will all cost a bit more.

Your biggest cost, as long as you act reasonably, would be a rent abatement for days your tenant can't use a property. 

Truck would be useful if you need to haul things but cost a lot extra in unnecessary gas money if you don't.

There may be some units that will cost a lot of money to get market-ready and keeping a long-term below market tenant may be more cost effective for the time being.
