Then I would replace the siding and paint the trim (check the windows while you're at it).

.- paint- trim- very light demo + dumpster- trim, a little flooring fix, commonizing the look and harden it (bath fans, remove storm doors, put fake bottoms in sink cabinets, add a tub grid drain, etc)- spring will need some concrete.that's it.

Trim painting is extra and install caulking at the top of the trim board and wall, it makes look better and it is cheap to do. 

We don't use gray, as most of our properties have wood trim in light or dark wood tones.

I'm comfortable taking up baseboard trim and re-nailing.

The exterior is vinyl siding and brick with some wood trim that's nicely painted.

I supply the washer and dryer there, because the doorways are so narrow that the doors have to be removed, AND the doorstop trim has to be removed, to just barely squeeze those appliances through the doorway; and the choice of washer and dryer was constrained to models that had small enough dimensions to fit. 

I am estimating at least 20k. needs garage trim, gutters, siding, house trim, tiles in kitchen, entrance, landing, bath is a full gut (what's new!)

On walls, ou shouldn't benusing flat Ron ow sheen and then semi gloss for trims.

As far as actual prices go, from my experience I'd say it depends on the level of trim but assuming the exterior and mechanicals are OK; I'd say 25-60 for a ~1300 sqft SFR...
