Snowbird CFO advisory: decide the US home with numbers, not nostalgia
Most snowbirds decide the fate of the US home by feel, and feel almost always says keep it. We replace feel with a framework: what the home truly costs to hold, what it nets if rented or sold after both countries take their tax, and whether your retirement cash flow supports the answer in both currencies.

Keep, sell, or rent: score all three paths on one page
The decision gets easier once the three paths are priced side by side, because they are rarely as close as they feel. Keeping the home costs real money every year; renting turns a personal asset into a two-country tax file; selling triggers withholding and a forced currency event. We put your actual figures into one comparison and let the spread speak.
| Path | Cash effect each year | Tax and filing load | Tends to win when |
|---|---|---|---|
| Keep for personal use | Carrying costs only: property tax, insurance, HOA, utilities, upkeep | Lightest — day-count discipline and Form 8840 where it applies | You use it four-plus months and carrying costs fit the plan |
| Rent it out | Rent offsets carrying costs, minus management and vacancies | Heaviest — US 1040-NR with the net-rental election, Canadian reporting with foreign tax credits, T1135 once it earns income | You want the home and the cash flow, and accept the compliance |
| Sell | One-time proceeds; carrying costs end | FIRPTA withholding of 15% of the gross price (Form 8288-B can reduce it), capital gains in both countries | Costs have outgrown the use you get, or the equity has a better job |
One number surprises almost everyone: Canada measures the gain in Canadian dollars at historical exchange rates, so a long-held Florida or Arizona property can carry a large FX gain on top of the property gain. That alone can swing keep-versus-sell, and it is invisible in a US-only analysis.
Keeping the home also means keeping the calendar. US day counts drive the substantial presence test, and many snowbirds file Form 8840 each year to claim the closer connection exception. It is a habit, not a hardship — but it belongs in the plan, because the tax test and the immigration limit count days differently.
Retirement cash flow in two currencies
A snowbird retirement is a matching problem: CPP, OAS, RRIF withdrawals, and most pensions pay Canadian dollars, while the US home spends US dollars all year. The fix is a written conversion policy instead of ad hoc transfers — a scheduled amount converted through low-cost channels, a USD buffer sized to a season's spending plus one surprise, and a rule for when a large USD expense such as a roof or a special assessment comes from the buffer versus a fresh conversion.
We also sequence withdrawals around the plan: which account funds the USD top-up, what that does to your bracket and OAS clawback exposure, and how the plan flexes if the exchange rate runs against you for a few years. The goal is boring on purpose — winters that never depend on the week's rate.
Funding the property: HELOC, US mortgage, or cash
The cheapest-looking money is not always the right money; the right money matches the asset's currency and your repayment plan. Each of the three common routes carries a distinct trade.
- Canadian HELOC: fastest approval and usually the lowest rate, but it stacks Canadian-dollar debt against a US-dollar asset, and interest on a personal-use property is generally not deductible.
- US mortgage: foreign-national programs exist — more paperwork and typically higher rates, but the debt matches the asset's currency and leaves your Canadian balance sheet unencumbered.
- Cash: simplest by far, at the cost of liquidity and concentration — and since US estate-tax exposure is calculated on the property's value, financing structure is worth deciding before you buy, not after.
Estate coordination: get the advisors agreeing before documents are signed
A US home is a US-situs asset, which means potential US estate-tax exposure for larger Canadian estates and, if held personally at death, probate in the property's state on top of the Canadian estate process. The Canada-US treaty relieves most modest estates through a prorated credit, but a US estate-tax return can still be required once US-situs assets pass the filing threshold. Relief is not the same as nothing-to-do.
Titling settles much of this in advance: joint ownership with survivorship, state-specific deed options, or trust structures each produce different tax and probate outcomes on both sides of the border. We do not draft documents. Our job is quarterbacking — putting your Canadian lawyer, US attorney, and investment advisor around one set of numbers so the documents match the plan, and the plan matches the analysis on our snowbird US property tax page. Fixed fee, quoted after a discovery call.
Common questions.
How many days can I spend in the US each year?
Immigration rules generally allow up to about six months per visit, but the tax test is stricter: average more than 120 days a year and the substantial presence test can apply. That is why many snowbirds file Form 8840 annually to claim a closer connection to Canada.
Will my estate owe US tax on our Florida condo?
Often no tax, thanks to treaty credits — but a US estate-tax return can still be required when US-situs assets exceed US$60,000. Filing obligations and tax owing are separate questions, and we map both.
What changes if we rent the home for a few months?
It becomes an income property: US 1040-NR filings with the net-rental election, Canadian reporting with foreign tax credits, and T1135 disclosure once it is no longer purely personal-use. We price that compliance into the rent-versus-keep math before you list it.
