The Life Arbitrage: Permission to Have Dessert by Mark Moberg, CFP®

Permission to
Have Dessert

You saved. You planned. You deferred. You skipped dessert at every meal because that's what responsible people do. And now you're sitting at a table you built with your own hands, wondering when you're allowed to enjoy it.

The Life Arbitrage is the book I wish someone had handed me before we left. Not just about the money and the visas, but about the moment you realize that the responsible thing and the joyful thing might actually be the same thing.

Most people think the thing stopping them is money. It's not. Find out what it actually is.

A book, a practice, and a question

The purpose was always
to have enough.

Somewhere along the way, enough became the purpose. Something about the life you're living doesn't match the one you meant to build. This is about what happens when you stop long enough to notice.

Life Arbitrage

/ˌlaɪf ˈɑːrbɪtrɑːʒ/

noun.

The practice of closing the gap between the life you're paying for and the life you could actually be living.

Why this exists

I ran the numbers.
Then I ran my numbers.

Mark Moberg, CFP®

Four years ago I was a financial planner in Florida with 25 years of experience, a CFP designation, and a family who'd done everything right. Saved enough. Planned enough. Deferred enough. And somewhere around year twenty, I realized I'd become the person this book is about. I had optimized the portfolio and forgotten the life it was supposed to fund.

So I ran my own numbers. Not the retirement projections I ran for clients. My numbers. What would it actually cost to move my family to Portugal? What would we gain? What would we lose? And what was I losing every year I didn't ask the question?

We moved.

And I made over $43,000 in mistakes. Not because the math was wrong. The math was fine. The mistakes happened because no amount of financial modeling prepares you for the thing that actually makes this decision hard: you are not just moving your money to a new country. You are moving your identity.

Now I do both. I understand the cross-border tax mechanics, the D7 visa math, the FBAR filing thresholds, and the estate planning that doesn’t survive a change of continent. But I also understand that your real obstacle probably isn’t the spreadsheet.

I teach financial literacy at an international high school. I run a practice that helps Americans figure out if this move makes sense for their life, not just their portfolio. And I write about the strange, beautiful, occasionally maddening experience of rebuilding from a place where you can’t read the road signs.

Everything on this site exists because I wished it had existed when I was where you are now.

Every financial plan you’ve ever been given is denominated in dollars. Net worth. Withdrawal rate. Portfolio longevity. The entire profession measures your life in money and then acts surprised when the life feels unmeasured.

But the asset that woke you up at 3am isn’t in your portfolio. It’s a wasting asset — the largest one you own — and unlike every other asset on your balance sheet, you don’t know its velocity. There is no statement. There is no quarterly report. You find out what the balance was by how little is left.

Ask yourself a question that has no comfortable answer. Who is wealthier — a person with enormous sums of money and one day to live, or a person with average savings and decades ahead of them? You already know. And yet the entire architecture of financial planning is built as though the first person is the success story.

The real arbitrage isn’t financial. It’s temporal — an exchange of one kind of time for another. And giving time the senior position is the first act of agency most people have taken in years.

You've read this far.
That is your answer.

You have a question about the money. Whether it’s PFIC rules, NHR tax treatment, D7 visa financials, dual-currency planning, estate portability, or something you haven’t been able to Google your way to an answer on — fifteen minutes with a CFP® who made the move and knows the cross-border mechanics. No pitch. No funnel. Just a straight answer from someone who’s seen the problem before.
