This may seem strange that I am confused about this, but hopefully someone
can help me.

I am remodeling some bedrooms in my house. They are lined up in a hallway
like this:

Bath Bed2
Bed3==================Bed1

(The "=" indicates the hall)

The hall, and Bedrooms 1 and 2, will be getting new carpet. Bedroom 3
already has acceptable carpet, so it will not be replaced at this time. I
also want to install new prehung doors for all of the rooms (including the
bathroom and Bedroom 3).

It seems like I have two options for the order of doing all of this:
1) Install all of the doors before the carpet team
2) Let the carpet team do its thing, then install the doors when I am
ready

If I go with #1, I will have to order and install all of the doors at once.
I'd rather wait and completely finish one room at time if I can.

If I go with #2, will this cause a problem with the carpet installation when
I remove the existing doors/frames for each room and install the new doors?
Do I need to let the sides of the new door jambs touch the slab (or get as
close as possible)? Would I have to be concerned about the seam between the
two carpet types between Bedroom 3 and the hall?

Thanks for any help anybody can provide.
