Here's some basic info on it:It's essentially rent ready shape aside from maybe some minor bathroom touch-ups, kitchen touch-ups, and exterior touch-ups.

Minor cleaning, touch-ups, lawn care, etc.

First, I would touch up on your local landlord laws. 

The discount that you gave him might not be a discount - I think there's room for reasoning between the two parties here because you do need to put in touch-ups for the next tenants.  

Our apartments were usually left pretty good.YA some units were a breeze and only might need a quick touch up.

Wood is a better insulator than vinyl so other then a more updated look and maybe easier to open windows I think I may follow suit with what you're doing and just keep the storm windows on and touch up the interior wood windows.

You'll find really good tips here on hardening your rentals, and you'll find it better to just paint all in one color to make it cheaper and easier for future touch-ups.  

This should take a handyman type and hour, and at most cost some touch up paint in materials. 

If you don't apply 2 coats any touch-ups you do in the later years will be noticeable....and I have heard all the painter excuses and "thick coat" arguments. 

If you say no, it's no...If you say that you will touch-up the spot/paint - you'll want the tenant to know:1.
