Home Mortgage – Blessing and Curse
what to do
Sometimes, while sitting on the couch with my wife, kids screaming around us, and the never-ending list of upgrades and repairs literally over our heads, we dream about the days when we lived in a 900-square-foot home in the woods. Small but mighty. Life was good back then.
Hindsight is always 20/20. Happiness AND dollars can be found in the LITTLE things. Why the roof over your head can make—or—break your path to Financial Independence.
TL;DR
Housing is typically the largest single line item in a budget. Treat your home as a tool—not a trophy—by running the numbers, weighing lifestyle trade‑offs, and squeezing every efficiency you can out of the bricks and sticks.
Don’t get me wrong, I’m a fan of the idea that YOLO, life is short, you should not torture yourself un-needlessly for money. It isn’t worth it. You spend your entire life in your home, so it should be a pleasant place.
Yet, things are more complicated than that, aren’t they? We can’t throw math out the middle.
1. Housing: The Elephant in the FIRE Room
According to recent MBA data, the median U.S. monthly mortgage payment hit $2,225 in January 2025 (bankrate.com), while the median asking rent across the 50 largest metros sits around $1,700 (realtor.com). For many households, that’s 25‑35 % of gross income, far above the classic FIRE guideline of keeping housing below 20 %.
When every extra dollar you funnel into PITI (principal, interest, taxes & insurance) is a dollar not marching toward your brokerage account, your home can feel more like a ball‑and‑chain than the American dream.
2. The Blessing Side of a Mortgage
Every principal payment builds equity automatically—great for those who struggle to invest the difference.
Leverage & Appreciation
A 5 % down payment gives you 20× leverage on home‑price gains; even modest appreciation can beat inflation.
Inflation hedge
A fixed‑rate mortgage locks in your largest expense while rents can rise unchecked.
Potential tax perks
Mortgage‑interest & property‑tax deductions (if you itemize), plus the §121 capital‑gain exclusion on sale.
Stability & roots
Long‑term certainty of payments and community ties—priceless for families with kids.
3. The Curse Side of a Mortgage
I mean, the paid-for house is the ultimate piece of the puzzle for those seeking FIRE and stability without answering to the bank. But, during those middle years when you are just grinding away on that mortgage, it can feel like a real drag on the finances and make you question what you think you know.
For the sake of trying to “steel-man” our discussion on mortgages, let’s give it a fair look, what could be the downsides?
Illiquidity – It’s equity you can’t easily spend without selling or paying fees on a HELOC.
Transaction drag – Realtor commissions (~6 %), transfer taxes, inspection fixes, and moving costs can vaporize years of appreciation.
Maintenance & CapEx – Roofs, HVAC, and water heaters don’t care about your index‑fund dreams.
Budget 1‑2 % of home value per year for upkeep.
Property taxes & insurance creep – These rarely decrease and can dwarf your actual mortgage payment over decades.
Opportunity cost – A large down payment could have compounded in the market instead.
A $100 k lump sum earning 7 % turns into ~$380 k in 20 years.
Geographic inertia – Job‑hopping (and geo‑arbitrage) become harder when your equity is nailed to the floor.
The bottom line.
A mortgage can be a blessing—one of the most powerful engines of wealth—or a curse that siphons cash away from index funds and stretches your FIRE date. Treat housing as a strategic lever in your plan: minimize costs where you can, monetize the asset if possible, and never let square footage crowd out freedom.
It’s super hard to not get caught up in chasing the Jones’s and get over your head with a mortgage that is simply too much or more than you need.
The last thing you want to be is house poor. Most people simply increase their housing costs to match their income as it goes up over the years. They see others moving up to bigger houses, see the new developments popping up, they watch to much stuff on Instagram.
Chasing happiness in a large house is foolish.
It will make you broke and the “new-car-smell” will wear off. There will always be a nicer neighborhood, bigger houses, there is always Jone’s with bigger toys than you, that’s just life.
Better to just be learn to be happy in the perfect medium. Find a housing arrangement that you enjoy, and doesn’t stress you out financially. Rocket Science.
