Upsizing in Ontario: The Real Cash You Need to Move Up, Line by Line

Your old home sells for $1.2M, so you have $1.2M for the next one? The money that disappears in between is the part upsizers almost always miss.

I am Arthur Zhao. In twelve years as a broker, the mistake I see most often on a move-up is treating it as simple subtraction — the old home sells for $1.2M, so surely there is $1.2M to spend on the next one. What catches people off guard is the stack of costs wedged in the middle: commission, a mortgage penalty, two land transfer taxes inside Toronto, bridge interest, and the weeks of carrying two homes at once. This piece takes no view on whether you should move or where — it is only about the money. I lay every bucket open and run one worked example end to end, so you know the cash to have ready before you sign anything.

The four buckets, at a glance

A move-up is not one transaction but four separate bills — split across the sell side, the buy side, and the overlap in between. Name the four buckets now and you will not discover a cash shortfall the week before closing.

Where the cash goes: sell side vs buy side

Sell side: what leaves when the old home closes

Selling feels like the side where money comes in. In practice it carries the second-largest cost of the whole move, after tax.

Prepayment penalty: three months’ interest vs the IRD

Buy side: land transfer tax — the largest single cost

For most move-up buyers the heaviest, most-underestimated line is land transfer tax. It is tiered and progressive: the higher the price, the higher the marginal rate.

Buying in the 905 saves an entire tax

That same $1.8M home bought outside Toronto’s city limits — Markham, Richmond Hill, and so on — carries no municipal MLTT, only the single Ontario LTT, saving roughly $32,475. This is not an argument about where to live — location is its own ledger — but put the number in your budget and the real cost difference between areas becomes visible. (This assumes you are a Canadian tax resident; non-resident buyers also stack the provincial NRST at 25% and Toronto’s municipal MNRST at 10% — a separate ledger.)

A note: the first-time rebate almost certainly is not yours

Both Ontario and the City of Toronto refund land transfer tax to first-time buyers, but moving up almost always makes you a repeat buyer, so neither rebate applies — budget the full land transfer tax and do not count on a refund.

Bridge financing: when the new home closes before the old one pays out

The most practical cash-flow problem in a move-up is that the money from your old home has not arrived yet when the new one has to be paid for. When the closing dates do not line up, bridge financing is that bridge.

How a bridge loan works

A bridge loan is short-term financing secured against the locked-in net proceeds of your old home — you generally need a firm sold agreement — so you can close on the new home now and repay in full once the old sale funds. It is usually quoted as the lender’s prime rate plus a few percentage points, plus a flat setup fee. Confirm the exact rate and fees with your lender. I do not quote a fixed rate here because it moves with central-bank policy — it is a variable, not a constant.

Bridge vs HELOC — the real trade-off

A bridge loan needs a firm sale and covers a short, defined gap. A HELOC (home equity line of credit) must be arranged in advance while you still own the home, but it does not require a firm sale and gives revolving, interest-only flexibility. If your old home is firm-sold and the gap is days or weeks, a bridge is usually simplest; if the timing is uncertain or you may carry two homes longer, a pre-arranged HELOC gives more control. Confirm rates on either with your lender.

The overlap: carrying two homes and moving

Even with the bridge arranged, the days-to-weeks when both homes are in your name quietly cost money.

Overlap and moving costs

During the overlap you may carry property tax, utilities, and insurance on the old home alongside mortgage interest, tax, and utilities on the new one. Add movers, short-term storage, utility transfers and hook-ups, and possibly a brief rental or hotel stay — a few thousand dollars is normal (get quotes from your movers and storage provider). Small individually, but all cash, and all bunched into the same short window.

One worked example, end to end

Here are the four buckets tied together with assumed numbers. The government taxes (both LTTs) are exact, computed from official rates; commission, legals, penalty, and moving are illustrative assumptions — your contracts and quotes govern the real figures.

Assumptions: old home sells for $1.2M ($600K mortgage balance, fixed rate at an assumed 4.5%, broken mid-term); new home bought at $1.8M inside the City of Toronto; new home closes first, old home funds two weeks later, so a bridge is needed.

In other words, on top of the price gap and your down payment, this move needs roughly $133K in additional cash — of which $64,950 is fixed government tax. Move the new home outside Toronto and that line is cut in half; move up past $3M while staying in the city and the municipal-tax line climbs further as the graduated tiers kick in.
