Touchdown! Greaser!
Don't forget to include the cost of a broken arm. Sigh.
I would just install a forced air furnace and the ductwork. Load cheaper than building a whole new house. And that 130 year-old house will still be here after the new one has rotted into ground.
I think a new house would have been easier.
I built my house about 12 years ago. Huge amount of work and frustration. I might tackle it again, but I think I'd get more professional help the second time around. Big problems with contractors not showing up and trying to do substandard work.
Oh - no one has mentioned the really pain in the butt part of this - building inspectors.
For the most part, they seem to be guys that couldn't hack it as a contrator and wanted a cushy job where they never have to take their hands out of their pockets. Some will pretty much leave you alone. But some feel a need to throw their weight around and don't like dealing with a home owner instead of a contractor who is more likely to buy them lunch...
