Florida Man Paid $600K for Skinny ‘Spite’ House, Says Size Is Perfect

• Mike Cavanagh bought a 10-foot-wide skinny house in Jacksonville Beach, Florida, in 2024
• It’s a spite house because its developer decided to build what he could given city restrictions.
• Cavanagh said he’s glad he bought the skinny house even though it attracts some curious onlookers.

This as-told-to essay is based on a conversation with Mike Cavanagh, a 51-year-old regional manager for a medical device company, who purchased a skinny house built out of spite in Jacksonville Beach, Florida, in 2024. The interview has been edited for length and clarity.

I realized it was time to downsize once my kids got older and moved out.

In 2020, I sold my 3,700-square-foot home and moved into a townhouse. I spent about four years renting, hoping the market would adjust, but it never did. I eventually decided it was time to buy something.

In June, I called a real-estate agent friend in Jacksonville Beach and said, “Hey, I’d like to see a few properties.” We toured three homes — one was a townhouse, and the other two were three-bedroom houses. None of them felt right.

Later, they called and said, “I’ve got something you need to see. It’s really unique.”

The moment I walked into the house, I turned to my real-estate agent and said, “I’ll take it.”

The home is 10 feet wide and 1,547 square feet, with two bedrooms and 2½ baths. Despite its narrow layout, the exterior has great curb appeal. Inside, it has a modern feel, with beautiful flooring and tile work throughout.

The same day I toured the home, I made an offer. It was accepted, and we closed in just 30 days. I purchased it in early June for just over $600,000.

The home feels like the right size for me

At first, I didn’t know much about the home’s history. What drew me in was the neighborhood — it was quiet and peaceful, which I liked. The house is also the perfect size for me since I’m single. If I were 40 with young kids, it wouldn’t have worked.

Eventually, I met with the home’s builder. He explained that he had owned the lot for a long time, and while neighbors wanted to buy it, he wasn’t willing to sell.

Originally, he wanted to build a 15-foot-wide home, but the city said no. So, he decided to do it his way and make the home 10 feet wide. That’s how its unique design came to be.

I’ve definitely acclimated to the home. It doesn’t feel small; its bumped-out walls give the house an almost container-like feel, reminiscent of an RV from the outside.

One of the home’s unique features is its built-in nooks. The upstairs bedroom has a built-in platform where my mattress sits, so I don’t need a bed frame.

Another important feature of the home is its natural light. The builder did an excellent job positioning the windows to create a bright, inviting atmosphere.

I hired a local designer, and together we developed a vision for the space.

I do entertain sometimes, but I don’t have massive dinner parties. I just wanted to create a great environment for working from home.

We added a built-in white oak couch in the living room with custom cushions. It was a bit pricey but totally worth it because it’s incredibly comfortable and has an artsy vibe. By the TV, we also installed built-in shelving and cabinets made from white oak.

I think the skinny house is a good investment

I think the fact that my home was featured on Zillow Gone Wild and that there used to be a “For Sale” sign in the yard both drew a lot of attention.

It’s more subdued now, but I occasionally notice random people driving by or walking past and making comments.

I still get jokes, too. Some friends introduce me socially as “the guy who bought the skinny house.”

Sometimes, when I meet my neighbors, they mention that they thought the house would be bought and turned into an Airbnb since there are plenty around Jacksonville Beach.

Compared to other cities in Florida, Jacksonville Beach has been slow to develop, which helps keep it affordable — especially relative to other beach towns.

As more people discover it’s a fantastic place to live, there’s been an influx of movers from the Northeast, some from California, and many from the Midwest.

My real-estate agent and I agreed that the house wouldn’t lose equity with Jacksonville Beach’s population growing.

If I change jobs or decide to move, I’m confident my home will attract enough interest to sell quickly. I could also rent it out on Airbnb. So I have plenty of options for the home in the long term.

But I plan to continue living in the home. It’s my only property, and my job is based in the area, for now at least.

Overall, I do think buying the home was a good decision. Smart people just don’t buy real estate to make money; they buy to have a great place to live — and to avoid losing money.

This home was definitely a solid investment.
