Does selling a house after less than a year automatically mean losing money?

Not automatically, but the transaction costs on both ends are real and they're the reason people usually suggest staying a few years. In my case I didn't treat those costs as a reason to keep the house, because they were already spent either way. I'll share what mine actually added up to once the sale is done.

Isn't rental income basically free money?

It wasn't free in my math. Rent has to be compared against what else that equity could be doing, plus the real costs and work of being a landlord. When I compared realistic rental profit against the monthly savings from a much smaller mortgage on my next place, the smaller mortgage came out ahead for me.

How do you know when you're making a decision to protect your ego?

For me the tell was that I kept reaching for reasons rather than numbers. When my justification for keeping the house was about how the last eight months would look instead of what the next few years would cost, that was the signal.

Why I'm Selling, Not Renting, My Townhouse

Why I'm selling instead of renting it out

I'm moving out of a house I bought less than a year ago, and the question I get every single time I mention it is: are you selling, or are you renting it out?

I'm selling. And I went back and forth on that for a long time before I landed there.

The short version of my reasoning: renting it out would have created some monthly cash flow, but it also would have kept a huge amount of my money locked up in a house I no longer live in. By selling, I can take that equity and roll it into the next house, which brings the new mortgage down a lot. The monthly savings from a smaller mortgage were bigger than what I could realistically expect to clear as a landlord on this specific place.

So for my situation, the math pointed pretty clearly in one direction. What made it hard wasn't the math. It was my ego.

The part I don't love admitting: my ego wanted a rental

It feels kind of ridiculous to buy a house and then turn around and sell it eight months later. I know how that looks. And renting it out would have let me tell a much better story about myself — that I didn't make a mistake, I made an investment.

When I actually sat with it, I realized that renting this place out was mostly me trying to emotionally justify money I had already spent. It wasn't me making the best decision going forward. Those are two very different projects, and only one of them is about money.

Naming that out loud was the thing that finally unstuck me.

What sunk costs are, and why they can't be part of the calculation

A sunk cost is money you've already spent that you can't get back no matter what you choose next. Buying a house comes with a pile of them, and so does selling one. That's exactly why people say buying only makes sense if you plan to stay put for a few years — the transaction costs on both ends are real, and they don't care how you feel about them.

Here's the trap I almost fell into. Because I'd already spent that money, I wanted a decision that would make it feel worth it. But holding onto the house wouldn't refund a single dollar of it. The money is spent either way.

Once money is already spent, it's spent. The only question left is which option gives me the best outcome from here.

I'll share more of the actual numbers once I've sold and can quantify what those sunk costs came out to. I'd rather show real figures than guesses.

How I compared renting it out to selling

I ran the numbers more times than I can count, and I tried to include every factor I could think of rather than just the two obvious ones. The pieces I kept coming back to:

The cash flow side. What rent would realistically bring in, not the best-case number.
The equity side. A large amount of my money is tied up in this house. If it stays there, it isn't available to lower my next mortgage.
The monthly comparison. Rolling the equity into the next place shrinks the new payment. I compared that monthly savings directly against realistic monthly rental profit.
The costs on both ends. Buying and selling both cost money. Being a landlord isn't free either.

For me, the smaller mortgage won. I want to be clear that this is my situation and my numbers — someone with a different mortgage, a different market, or a different appetite for being a landlord could run the same exercise and land somewhere completely different. The exercise is the transferable part, not my answer.

Separating what feels validating from what adds up

I think this is the genuinely hard part of money decisions, and it doesn't get easier with a spreadsheet. The spreadsheet was never confused. I was.

What helped me was asking a slightly different question. Instead of "was buying this house a mistake?" — which is a question about the past and has no useful answer — I asked "if I had this equity in my hands today, where would I want it?" That version of the question ignores my pride entirely, which is the point.

The decisions that have cost me the most weren't the ones where I got the math wrong. They were the ones where I let the math argue with my ego and let my ego win.
