These are old original windows where I have repainted peeling paint many times over the years. 

@Ryan Johnson Did you have to get it repainted every 3 years or so?

We just had someone move out of the unit two days ago and the space immediately rerented for $550/mo with ZERO downtime and repainting a couple of walls.

We are not charging them for the siding which their children drew on or the walls as we will be repainting the entire home and residing the house (old siding and might as well do it since we have to do the windows). 

.- updates include:- replace a broken window- add in-unit washer dryer- remodel kitchen- update bathroom- estimated budget: $20,000Unit 2 (3 bd/ 1 ba): Currently Owner Occupied - Rent for 1700- updates include:- update bathroom- re paint to match the unit below - unifying paint colors across all units seems to be a good idea- new door and closet in the third bedroom, currently configured as more of an open office-estimated budget: $10,000I

We're gutting the bathrooms and kitchens and starting from scratch, then doing minor improvements (resanding floors, repainting walls) through the rest.

Replaced older carpet with laminate flooring, repainted entire house.

You'll have drywall cracks, so you should factor in drywall repairs and repainting. $$$4.

In regards to estimating repairs, have you seen this, I thought it useful https://www.biggerpockets.com/renewsblog/2015/10/1...Also, vacancy rate isn't just lost rent income, there is tenant placement fees, and cost with getting the unit ready for a new tenant such as repainting etc.

I too just wait till I get possession of the unit because there is always repair, repaint, repositioning of the unit to get a higher rental fee.
