Thank you so much for the recommendations. The main issue is that I am causing myself overwhelming anxiety by looking at pictures because I'm not even sure what my "style" is. The kitchen has stainless appliances, and we will be purchasing new furniture for the living and dining area. The only furniture we are taking is a Z Gallerie Harrison sofa in Brussels (it's a silver color), and a square dark distressed coffee table with rubbed oil bronze hardware.

!st that sofa and that coffee do not work together and neither are MCM if that is the period you are trying to stay in. Google MCM living rooms and others it will give you some ideas .I would at least remove the backspalsh in the kitchen and replace with something simple and a lot easier to keep clean.

I will gladly take your advice. I do love my sofa, but, not as much as my OCD loves uniformity. Thank you for acknowledging that there is no way I can make my precious work in the new home. (I hope that didn't come across crass) My next, and by far largest headache is the curb appeal. I have attached pictures of the house I lost to a cash investor. Are you able to recommend s key words to search for? I promise to not pester you anymore, you've been a great resource.

You have a big space and three functions: kitchen, dining room and living room. There is a lot of floor.
First: Have you edited what you will be bringing to this home?
If you are keeping a current sofa, its measurements may help you select a size for a large rug for the living room seating arrangement to occupy.
If you have a dining room set, you can look at a rug for that space: I work with a rule...the rug should be four feet wider and four feet longer than the table top (fully extended if you ever use it fully extended). That measurement allows for people seated in each chair. Any related storage or serving piece can sit on the wood floor.
The rugs for the two areas may match or just coordinate well.
You want to keep to the era of the 60's, so search Houzz for 60's or mid-century rugs or photos of rooms from that period. Your walls are perfect for large art pieces.
The kitchen isn't very 60's, but you can play up the period with wall art and more modern-looking countertop appliances. Houzz can show kitchen photos to help you.

Is the home you purchased similar to the exterior photo of the home you lost to the cash investor? I ask because I don't see MCM in the interior photos, i.e., the kitchen cabinets look Traditional to me. The good news is you have have fantastic space to work with. Browse Houzz photos and save rooms that appeal to you. You will soon see what you lean toward versus what to avoid. This might help you define your style and help to refine your search. Don't put a label on your style until you determine what you like. Finally, DO NOT PART WITH THAT SOFA. It's gorgeous. You love it. Make it work. Work with it.

Wow, just wow! Everyone is amazing!
The exterior of the house we didn't win was as boring (green and yellow) as the one we're purchasing (It's slate gray), which may have been wishful thinking.

The person who gutted the personality of our new home replaced literally everything in every room. Granite everything, cabinets, fixtures.

Thank you for the sofa comment. It was my first time falling in love with a sofa. it pains me to think of putting it in a game room.
