In theory, Tuesday the electrician and plumber will make sure that the builders can safely have power and water. Then a long weekend as there is a small wedding on Friday. The following Tuesday the builders move in and will remove the back of the garage, the roof, part of the chimney, a wall in the bathroom, and replace a kitchen ceiling and build a new roof, and so on. Hopefully by the end of May/beginning of June, we will have a habitable house that doesn't smell.
The tricky bit will be keeping a lid on the budget...
I realised that you haven't seen the front of the house. It's really quite a mess. Just look at its potential - try. I know it's difficult.

Oh, and have a Happy and Blessed Easter.
Christ is Risen!
