The tub scratches are from people who wash things like tricycles, metal shelving and cleats in the shower.

My buddy owns a good sized metal recycling business in Everett.

An example of this is 30 year commodity cycle (commodities peak every 30 years: 1920, 1951, 1980, 2011 etc) which bottomed in 1999 where gold can purchased at $280 / ounce in 2001 and one could have held onto this investment for 10 years and unloaded all their precious metal positions at $1920/ounce at the end of the cycle in April of 2011. 

I nkow I could add an A-coil and condenser to the furnace for central air, but in this price range it doesn't really matter if they use wall ACs.I think I answer my question already, but what do you think?  

BUY quality SINGLE FAMILY homes SFH.that appreciate.4.Always do a home inspection using a certified home inspector ( with utilities turned on) and separately  hire an A.C. company to thoroughly inspect the state of the HVAC ( it might be blowing cold air today , which passes a home inspectors test) but the coils might be shot and the system riddled with leaks and crushed air handling tubes.

Central air is when they put a coil and condenser on the the forced air system so that the duct work is shared between the two. 

But nobody removed the old metal gas tanks, which had been rusting away since the 1930s.The laws are such that any owner in the chain of title can be liable forever for any environmental problem with the property.

The later is what you would need for that amount of space.These prices include sheet metal fab for trunk if necessary.

@Jeff Lee I would def contrast it, and its a simple roof so you may look into metal.

You said outdated so I assumed metal roof, metal siding, which could go for between $2,500-$5,000.
