My family just moved into a new house and it's awkwardly laid out. We are planning on moving in another year or two and we want to fix up the house enough to profit from it, but to also make it as comfortable as needed. Therefore price is a real concern.

One of the plans we came up with involves moving the front door to the other side of the front room, a move of about 17 feet. We would be covering up where it is at the moment, and cutting into the house on the other side to create enough space for the door + a small porch step. Our house is older, made probably in the 60's or 70's, therefore we know there might be some structural difficulties.

Is it possible to move the front door without it eating up too much money? Or is it really just based on the structure of the house?
