That is what I initially thought at first too. The

Sink - wear and tear (stainless polish like ZEP or 3m and elbow grease, which should be part of a normal turn anyway).Garage door panels - wear and tear, cover them with pieces of same colored duck tape).Cat scratches - wear and tear, if they are real bad, use appliance touch up paint.Sink drain = misuse, I would charge 100% of cost to replace.

Let the designer also pick out all the paint colors and light fixtures. 

Usually, only heating oil USTs associated with commercial properties are regulated. thus, most home heating oil tanks may and often are taken out of service without any oversight from state regulators.Second- the rules that are in effect for heating oil tanks are usually less stringent than for diesel or gasoline tanks since heating oil tends to thicker and may not migrate as far. as a result, many states just require tanks to be cleaned out. they may also require the tanks to be filled with sand or concrete to prevent collapse. but sampling may not be required.Third- the key to determining if a tank has leaked is to collect soil samples from around and beneath the tank (groundwater also if groundwater is shallow). another quick way to see if a tank is leaking is to "dip" it with a stick that has a paste that turns color in the presence of water. generally, if water has gotten into a tank, it can mean oil has leaked out of the tank (although a certain amount of condensation may be present even where there is no leak so this is not a infallible test).Fourth- if there is currently a tank in the basement, ask the owner if there used to be a buried tank (a/k/a underground storage tank).Fifth, If the tank has impacted the soil, the cleanup generally varies from $25K to $50K though the costs will depend ont he depth of the contamination. i once had a home with a heated pool that had pressurized piping and used diesel. the contamination went down 40 feet and the consultant went crazy excavating the soil to the tune of $400K!!!

Stainless does better but if not stainless make sure they are at least the same color.

The color / paint will fade/fail before the metal will. 

I don't think I could add much other than if you have older properties with steam boilers to check the water levels and coloration on a consistent basis to make sure system is operating at peak efficiency. 

Heck, even just asking to schedule a visit can get a scammy provider to show their true colors. 

Take a list of attendee names then track those people down too. The

Fresh paint in warm neutral colors like greys are popular nowadays.
