One of mine is "balloon" framed, and while there's nothing wrong with that method per se, it led to some issues with sagging and bowing of walls, floors and headers. 

My main issue is I'm now facing necessary replacements for large items that can no longer be repaired (back deck, portions of our front porch, wiring we discovered was unsafe, joists separating from the headers). 

That will bring up the search box in the black header bar. 

The only way to know the difference is based on whaat it says in the header or (if you are the one asking for it) what you ask of the lender.

So you now get to pay for structural supports likes headers and beams and posts...just like a stick built building. 3 - You still have to meet all the same building and energy codes.

I know this is a safety and efficiency issue3) Remove the unit and just rely on the electric radiant headers in the baseboards.   

I just opened walls on a old place I have and found the sill plate was basically all gone and It was load bearing with 2x3s and no header over a window.

A header that spanned a good part of the house totally rotted away due to termites and moisture.

You may consider advertising it 1-2 weeks early with a COMING SOON header and clear instructions that it's not available for in-person showings until after a certain date.

If you start looking at changing window sizes/locations, this cost will grow exponentially as you bleed into siding re-work, new headers, opening walls, etc.
