I would absolutely strip it down. Buyers generally want to see natural light and a decluttered space. Keep a couple plants, but there's a lot that can be removed. They are buying the space, not your decor so make it more neutral so they can appropriately see what you're selling.

But if you have a really hot market it will sell anyway. All depends on your market. But even in a hot market when a cardboard box on the sidewalk sells, you'll get more money (probably) and move it faster if it's stripped down. And I do mean brutally stripped down.

See "white box" thread.

in our market, every small condo that was somehow successfully customized and used upgraded finishes, got a lot of attention from buyers, and went under sale much faster. Sometimes momentarily. It shows investment in the space and usually is an evidence of great maintenance. As I was closely monitoring the condo market here(we're in So Cal, I don't know where you are at) for several months before we bought condo for my MIL, that's what I noticed. So while I'd declutter of course, take lots of stuff away and lighten up a bit-and all-I'd leave it as is.

I also prefer though carved out spaces in a small place that can be used in all sorts of ways, to accomodate guests, different activities and all.

But I'm not unique in that matter.

Do talk to realtors, and when time comes to put it on market, your chosen realtor should be able to present different opportunities to the property, like mentioning what can be converted back easily, etc.

Here at least, your place would be an instant hit with the buyers. Wallpaper or not. Bonus if you added/organized storage.

I need to add that condos here, especially in some complexes, are very desirable for many, and it's hard to find a good condo for a good price.

Your decor would be ok in the northeast but in FL it won't fly because it is dark and closed in looking. People wanting a condo in FL, especially those who are younger, want light and bright. I absolutely would strip the wallpaper, open it up so it's not "rooms" and make it as generic as possible.

I would switch out the crystal doorknobs and bronze switch plates for generic HD ones. I tend towards craftsman style and when I went to sell my condo in SW FL a few years ago, I had craftsman style light fixtures that I had paid a pretty penny for. I went to HD, got inexpensive fixtures that instead of having colored glass were white, and hung those. I took my expensive fixtures and put them in my new house.

I also had a few cabinet pulls that had been expensive, so I took those off too, and put on generic HD pulls.

All good points above. Talk to a trusted experienced Realtor in your area as they will know your specific market. In general, each condo community has a certain personality that attracts different buyers (young professionals/empty nesters/retirees/boaters/etc). You don't have to go entirely neutral, however, it will open up your condo market to more buyers if you neutralize what you have now.

When you have personalized your space to the extent that you have, you limit the market to those buyers only looking for very heavy traditional decor; which is polar opposite to the condo market here in S Florida (generally). Wallpaper is particularly difficult to pull off when selling these days. Having the various rooms you created out of the space can limit your market too. This is why you want an experienced, knowledgeable Realtor to come see it and tell you what the target market is for your condo and what that market is seeking.

One last comment: today marketing your space is heavily dependent on photos. Professional photos of your space make all the difference in marketing your listing. If the space appears cluttered or small, you will lose buyers. They simply will skip your condo and not call their agent to see it. Contrary to popular belief, even in very hot markets there are properties that do not sell. Usually the reason is because the amount of work, or perceived work, is too much for the price point. It takes seconds for the buyers to swipe right over your listing to the next one that is more appealing to that buyer. Removing wallpaper is high on the list of work projects that buyers just don't want to tackle.

Go to Zillow. Look at active for sale listings and sold listings that are in your development. If your condo doesn't look a lot like the other condos that have sold, your finishes are well outside of the target market.

You have only provided two current pictures of the condo. From just those pictures, it looks like your have a lot of clearing to do. I see heavy window coverings, too many plants and something on every surface including the top of the partition. I think you have a lot of work to do.

You need to consider this space as no longer yours. You have to put in to your mindset that someone else already owns it. That makes it much easier to make changes. Good advice was offered to speak to an experienced realtor. They may refer you to a professional stager who can help you with the process. Pictures on line are everything now days. Everyone shops on line before they ever call their realtor.
