Cost to touch up a 800sq ft unit?

[Francis Rusnak]

I just got what seems like an abnormally high estimate of 10k to touch up each unit in a multi-unit complex when renters move out.

For background the building is in Columbus, Ohio and each unit is a 3bed approx 850 square feet. The goal is to bring rent from 675 to 750 and eventually 800/month. 

I was thinking a normal amount to touch up a unit after someone moves out should be 500-1k (about what a security deposit is). To upgrade and make the unit nicer would be a couple grand, maybe 3k. 

Am I way off on my estimates?
