You do not say what the old floor is. I assume it is hardwood
based on your reference to using a circular saw.

This is one of life's no-fun jobs. Cut as much as possible with
the circular saw. The remainder of the cut requires something
different.
Choices:
Dremel type tool
Roto Zip type tool
Sawzall
Utility knife and sharp chisel.
Bosch makes a straight blade finish saw. See:

Kett makes a great trim saw, though it won't go the whole way
either:

I need to cut a wood floor between two rooms so I can replace the
floor in one room. Normally I would use a circular saw and
stright edge, but what do I do near the wall where the shoe of
the circular saw will get in the way? I need a nice straight cut
because this will be in a very noticeable location.

Is there a special saw for this or any suggestions?
