OK, here is the house timeline.
keep in mind that this is the worst case. I think.

Bank status.
The appraisal will be 2-3 weeks.
The title will be 2-3 weeks.

Building status.
Excavation 2 weeks
Foundation 2 weeks
Wall erection 2 week)s
Interior wall erection 2 weeks
Plumbing 2 weeks
Electrical 2weeks
Doors n windows 1 week
Roof n gutters 2 weeks
Drywall 3 weeks
Exterior 2 weeks
Cabinets and floor 2 weeks

Not sure what it adds up to, but it should be no later than May 1st.

Much longer than we thought! Partly because we can not get in until it is completely completed.
