I got very different quotes from State Farm and American FamStatefarm came up with a replacement cost of $525K and an annual premium of $4,200.

Although I agree that the sub-floor should not be called hard wood, that yellow pine does look really good once it is sanded and finished.

The wood panels are as low as $25-40 a piece.

These are plywood cabinets made from wood grown in the US (depending on the wood type), fabricated in China, assembled in the US, and require a 5 week lead time. 

Alternatively, a small piece of wood molding could fill the gap as well.

.- You should know which type and color of wood flooring, carpet, and tile.- You should know where that flooring will go.- Know which light fixtures you want and where you want them- Know what color you want to paint the walls, ceiling, and trim of the interior- know which color you want to paint the exterior walls and trim- you should know what you want for fine detail items such as the mantel of a fireplace.In order to help you select these items, I recommend looking at houses near yours that sold quickly such as having gone "contingent" within the first week of listing and copy these finishes.

But for something from around 1920, it may have already been refinished several times; I recently had 1920 vintage wood flooring refinished, and it does not look like there will be another sanding left ...One thing not yet mentioned is that 1920 vintage housing often used heart pine planks as the subfloor.

Paying inexpensive premium.
