Can I save $1000 in paint prep costs by ripping out the old trim and spending $500 on new stuff?  

We looked at the situation and determined there had been forced entry that caused some of the interior door trim to fall into the entry way and found another piece of the interior door trim in the outside bushes.

I just closed on a beautiful house (4 Bed, 2.5 Bath, 2400 SF, with all the trimmings on 1/4 Acre on a Cul-de-sac, 20 minutes from downtown).

Could you put in a neat white/Black/stained trim “frame” around it like built in art?

Of course, then you have to install a gas line (Hard to do if you're on a slab), and trim the thing out, and worry with it, and... blah blah blah.

Doors are cheap....check out habitat for humanity re-store, the one here has tons of hardwood raised panel doors and you can trim many of them out to size.

You can pass every inspection in the code book and end up with a terrible paint job, sloppy trim work, and a multitude of other unprofessional finishes.  

If he just tries to quickly do it, he can spill paint on the floors and also get paint all over the wood trim. 

Walls only (no trim) is a pretty cheap investment.  

However....when more inventory comes on market,,,,,other sellers may think....Ooh, Jack and Jill sold there's for $1.1 Million 2 months ago and they were asking $1.05 Million.....let's list ours for $1.15 Million because surely the market will have gone up since then and besides our garage looks better than theirs as does the white trim around our brass railings....I've seen it happen time and again when it comes t supply and demand. :-)
