I agree with Pam about the function things, but, at least where I live, having the kitchen fit the style of the house, aesthetically, will have the greatest visual appeal. Make the whole house cute! Use the original kitchen as a style cue. Sochi phrased the plea not to lose the MCM as personal--I'll extend it to the rentability. Renters want function function function since there's nothing they can do about anything. Having the whole house read as a single style makes it so much easier to furnish and live in, and makes the house make sense to the renters when they're walking through while it's empty. I've lived in a '30's beauty of a rental with an unadorned, clean '70's kitchen, which wasn't bad. It was all function, white slab cabinets, white tile, and newish appliances. The kitchen had no charm but had lots more function than the '30's kitchen would. Lots of cabinets. Separate cooktop and ovens. Garbage disposer and dishwasher. So that was fine, if unexciting. The rest of the place was really cute, and had the original hardwood floors and walk-in closets, plus original tile and huge tub in the bathroom. Then there was the early '60's place with the panelled wall in the living room, panelled den with built-ins, and pink kitchen. Original, very clean, appliances. It was cute! The whole house was cute. The original kitchen, with it's display cabinet peninsula was cute. The panelling was a bit of a gulp, but it was clean and unmarked, and went so well with the style of the house. My furniture looked just fine. And the kitchen was very functional, other than too wide an aisle. Lots of cabinets, and more in the laundry room. Okay, as a former renter? LOTS OF CABINETS!! That's the ticket to pleasing a renter. And cute. Renters want the place to look like something. Keep that MCM thing going. Anyway, slab cabinets are easier to clean between renters. :) I also have experience from the landlord perspective (including surveying the competition), which also says that closets and cabinets are worth extra $$$, but generally, you'll get your rent based on location, pleasantness of surroundings, space, upkeep and storage. Utterly bland will rent at full price. Too much character (e.g., mauve walls or anything "weird") won't rent well, but a little style with neutral colors goes a long way.

That's a nice home. I'm not very good at these things, but I wanted to suggest you post on the home decorating page. You will definitely get a lot of responses there.

"Home, home on the range...." Look at the homes of leading mid-century modern architects--Gropius, Schindler, van der Rohe, Marcel Breuer etc. If you like their work, seek out an architect who has penned homes in that style. Ranch/range houses are a dime a dozen from the on-line houseplan mills.

We have a colonial house with some danish modern furniture plus Persian rugs and a french 18th-century table, modern and traditional art. I like it because it doesn't look like it was bought at any one store. You can totally mix looks and honor history. I like the other suggestion of reducing the number of chairs (just bring them out when you need them) and modern pads and fabric. I would keep the table, put some color on the wall, and maybe an oil painting. If you do travel photos, maybe do a few really large ones vs. a lot of little ones. And make sure they are really classy, not just shots of grinning people. More formal art will help balance the formal table. And the wall could be darker to complement the wood (warm yellow (BM Country Comfort) or goldish?). My living room is BM peau de soie which looks pretty nice without being overwhelming (dove white trim).
