Ohhh, yes. It sounds so charming. I would stay and enjoy it for a while, too, especially in this market. At least enjoy the summer and then sell in the Fall.
My house was built in 1939 by a couple with no kids. They put all their savings into building a sturdy house with all copper pipes, the best materials, blah blah blah. None of the oak floors have subfloors. When you mop the first floor, water drips onto the heads of whomever happens to be in the basement. This is the first house I've seen with just floorboards laying across rows of 2x4s with no subfloor. Weird.
We also have old windows and sills all over the place. We have one built in in the dining room (china cabinet), and all original doors and hardware. A favorite feature is a big glassed-in front porch (old, swing-in panes all the way around).
Our attic could be turned into another room, but I'd rather install air conditioning in the house, and we might have to put a unit in the attic depending on the type of air conditioning we get (old plaster walls, no duct work anywhere, radiators throughout). That project will happen when we discover a magical $15K that we didn't know we had. (Right.)
The worst feature, especially because I cook all day, is the TINY kitchen. It is maddening... barely any work surfaces at all, and certainly no room for a table. So, my dining room is my home office, craft table, and where we sit to eat (after a whirlwind cleanup of whatever projects are spread out at the time). My dream (more like a fantasy) is to bust out the back and build a gourmet kitchen with a master suite and small deck above it.
A previous owner took a corner of the foyer and built a small powder room (tiny corner toilet and tiny pedestal sink). That extra toilet in the house add so much quality of life for us and for guests. Not sure if your house has space for an addition like that, but it wouldn't be too expensive if you don't bother with tiling, etc.
Oh, I could go on and on. I love houses, especially ones that have charm. They're so much fun to decorate, too, because you're already starting off with tons of great detail.
One drawback: Drafty old windows make it pretty hard to wear sexy stuff. It's freezing in here! (hmmmm... fleece body stocking with access hole... cashmere babydoll with leg warmers and knit choker.... thermal bustier and thong with fur robe...)
