New exterior paint.

First off, you do paint sort of worst case scenarios. 

We put in new floors, resurfaced the stipple ceilings, and painted all the walls and trim.

This way, the future buyer can provide direction on the paint colors, flooring, etc that they want as you complete your flip.

. I have seen situations where landlords and tenants are both very firm on their requested rent price and it was a minimal difference and the landlord let them move out and the money it cost the landlord to clean fix paint and rent the unit out to a new tenant outweighed the difference they would have made the tenant after moving expenses and paying first class and Security again probably outweighed what they would’ve paid had they just stayed so sometimes it’s better to just negotiate and flex a little to renew a tenant than to keep swapping tenants.

When tenant moves out my wife and I will clean up real good paint and patch on a Saturday afternoon. 

Add estimated costs of new flooring, paint, drywall repair, and countertops using the quality of products expected in that neighborhood and double that estimate.  

Old paint can contain lead, as well as water pipes.

Put a few paintings or fine art photographs on the wall with QR codes for purchase and they will serve as constant reminders to your guests and conversation pieces in their homes. 

I dont paint/change colors or replace flooring unless I decide they need to be done... not the tenant.....
