US rental portfolio CFO advisory: refinance, sell, or buy the next door?

Know your real return: cash-on-cash, in one currency

You cannot manage a cross-border portfolio until every property reports the same number: cash-on-cash return in Canadian dollars, after both countries' tax. Cash-on-cash is annual cash flow divided by the cash you actually invested. For a Canadian owner, that cash went in at one exchange rate and comes back at another, so the US-dollar figure alone can flatter a weak door or hide a strong one.

As a plain illustration: a property clearing US$9,000 a year on US$150,000 invested is a 6% cash-on-cash in US terms. If the loonie has moved 10% since you funded the deal, the CAD-measured return is a different number — and that is the number your net worth actually lives in. We build a per-door dashboard showing both, translated at a consistent monthly rate, so the trends you act on are performance, not currency noise.

Refinance or sell: run both against the next-best use of equity

The refinance-versus-sell question is really one question: what is each dollar of trapped equity earning where it sits, versus where it could go? As a property appreciates and the mortgage amortizes, return on equity quietly falls even while cash flow looks fine. That is the moment to model both exits properly, not when a tenant leaves and emotion takes over.

The cross-border wrinkles change the answer. A sale by a Canadian triggers FIRPTA withholding of 15% of the gross price — reducible with a Form 8288-B application — plus capital gains tax in both countries with foreign tax credits to reconcile. And the popular US deferral play, the 1031 exchange, usually breaks for Canadians: the CRA taxes the gain in the year of sale regardless of what the IRS defers.

We model both paths with your actual mortgage quotes, your actual rates in both countries, and a named redeployment plan for the cash — because equity pulled out with no destination usually ends up spent.

When to add the next door — and when to wait

Buy the next property when three gates open at once: reserves, financing, and management capacity. We formalize each gate so the decision becomes mechanical instead of emotional.

• Reserve floor: a set number of months of mortgage, taxes, and insurance per existing door, held in USD, before any new down payment leaves the account.
• Financing reality: foreign-national and DSCR lender programs price differently from the loans US residents see advertised — we pre-underwrite the deal at terms you can actually get.
• Management capacity: who takes the 2 a.m. call, and does a second market double your oversight load for a marginal return?

Concentration counts too. Five doors in one Sun Belt metro is one insurance market, one landlord regime, and one local economy. Sometimes the right next door is in a different state — or nowhere yet.

FX strategy in plain terms

You do not need derivatives to manage currency risk; you need to decide which currency each dollar lives in, on purpose. Three plain moves cover most owners.

• Use the natural hedge: US-dollar mortgage debt against US-dollar rents means the exchange rate largely nets out on the operating side.
• Stop round-tripping: keep a USD operating account for repairs, insurance, and taxes instead of converting twice and paying the spread both ways.
• Hedge events, not operations: a forward contract can make sense for one large, known conversion — a sale or a major repatriation — not for monthly rent.

Scaling from one door to ten runs on systems, not memory

The owner of ten doors cannot be the spreadsheet. We stand up per-property books — QuickBooks Online with classes, or Stessa for simpler portfolios — a monthly close, and a one-page portfolio report: cash-on-cash per door, return on equity per door, reserves against the floor, and the decisions coming due.

Then we run a decision calendar with you: lease renewals, insurance renewals in hardening markets, refinance windows, and both countries' filing deadlines. The tax mechanics underneath — 1040-NR net elections, T1135 reporting, foreign tax credits — are covered on our Canadians owning US rental property page; the CFO work is making the decisions those filings later record. Fees are fixed and quoted after a discovery call, so advice never meters by the question.
