A $750 fee to waive an escrow impound account sounds costly. If you otherwise like the mortgage offered by the builder, I would negotiate hard with the mortgage broker or the actual lender to cancel that fee. Of course, shop among other lenders to see if you can do better elsewhere.

Whether a wooden ship the size of Noah's Ark could be made seaworthy is in grave doubt. At 137 meters (450 feet), Noah's Ark would be the largest wooden vessel ever confirmed to have been built.

Even so, these wooden ships had a great advantage over Noah's Ark: their curved hull shapes.
