They may have requirements beyond State of Maine requirements.I'm not sure of the scope of your renovation, but one of the blessings of a full renovation is that all that old lead covered trim, doors, cabs, etc is pulled out of the home.If you're going back and forth on how much reno to do on this project before you rent it out, read carefully the abatement section on the link below. 

Maybe the curtains, ceiling, cabinets, baseboard and trim, or a variety of places.You could try running an ozone generator to see if that helps.

Paint all the walls, ceilings, doors, trim, cabinets. 

A water heater will often last 9-12 years, I saw one yesterday at an inspection that was 24 and still cranking.Also consider non mechnaicals like floors, light fixtures and interior doors and trim, kitchen cabinets etc..

I needed to caulk, trim paint and the biggest thing was pressure washing the rear deck because the previous tenant had potted plants on it for 4 years... a bit of a pain because it's a very humid environment down here so wood rot is prevalent.     

(painting, gutter work, minor landscaping, tree trimming, etc).

We started by cleaning out any evidence of animals and repaired the damage they had done to the trim and walls.
