If things dilute to the point where everyone is running a special for market share and you are getting 10% then you can sell and put that money to work in better alternative investment.I have wondered about getting into investing in businesses like they do on Shark Tank. A

Probably going to do the hot water tank as a rental...  

I needed to sell my house, but the market was in the tank. A

I think SK market will not tank as it has already correct itself for the over supply and new construction pressure created.

They also put in a new heat pump and removed the oil tank as the oil furnace had died. 

There is a below ground tank, but for some reason they have a jury rigged above ground tank as well.What am I looking at to replace the existing oil furnace with an electric one for a house with a basement, about 2,500 SF?

I have several 500 ft units heated by baseboard via their gas hot water tank. A

there are two ways to properly close a tank: remove tank or clean it and fill with inert material. sounds like seller has not fully complied with tank closure requirements.soil samples should have been collected from beneath the tank as well as the sides. groundwater samples should also have been collected to make sure old spills did not impact groundwater.

By that point, the hot water heater that had rusted out the bottom and was leaking water all night, adding more water in the tank as it was coming out the bottom. 

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!!!
