Answers:    It might be cheaper to start new. Which is going to cost more to do, build a house "dry to the weather" and finish the inside to fit you, or gut a house near old window, roof, etc...

I usually build new homes, but hold done enough remodels to explain to you that remodels are very expensive if you are going to do the adjectives house.

If I had my choice I would build a unknown home to take plus of energy in your favour new building items similar to vinyl windows, glorious density insulation, etc...

I would be very punctilious in picking the house to remodel.

Either approach it is going to cost a lot of money!
Sorry, within is no way to confer you even a ball park quote because within are too many variables within your question.
Average home cost more or less 85 dollars a square foot to build, and that is a unfinished house, not granite counters and stainless steel appliances. If you give me more detail I could ballpark it, but a underpinning price of 45 dollars for interior re work would not be too far off.
