You own a Vancouver lot. Probably for 15, 20, maybe 40 years. A developer sends you a letter. A neighbour mentions they “co-developed” and kept two units in a new building. You Google it. Now you’re here.
The question underneath the question is not “should I co-develop?” It is: what do I actually want from this lot, and which path gets me there with the least regret?
Let me make the framework simple.
The Two Paths on the Same Lot
Take a standard 33 by 122 foot east Vancouver lot. Current assessed value: $1.8M. Under R1-1 co-development rules, it can support a 4-unit multiplex.
Path A: Clean sale to a builder. You list the lot, receive offers, pick one, close in 60 to 90 days. Cheque clears. You move on.
Typical 2026 Vancouver east side outcome: $1.75M to $1.95M gross. After real estate commission (~3.5%), legal, and minor adjustments, net proceeds around $1.65M to $1.85M.
Path B: Co-development with a land-for-units swap. You contribute the lot at an agreed value of $1.8M. Builder funds the $2.4M build. At completion (22 months), you receive two finished strata units worth roughly $1.4M each, or $2.8M total.
Net delta: roughly $950,000 to $1,150,000 in extra value for the same lot. That is the headline number. It is also a completely misleading number unless you understand what you’re trading for it.
What You’re Actually Trading
You are not trading “selling” for “more money”. You are trading:
- Certainty (cheque in hand) for contingency (units that exist in 22 months, if everything works).
- Speed (60 to 90 days) for a two-year process with multiple decision points.
- Zero post-sale involvement for an active partnership with a builder you just met.
- One simple tax event for a complex matrix of GST rebates, Principal Residence Exemption change-of-use, and Property Transfer Tax on new units.
- No upside for upside and downside, because markets move.
If you sell and the market goes up 20% in two years, you missed it. If you co-develop and the market drops 20% in two years, your retained units are worth less than the land you contributed.
The Honest Framework
Here is the framework I give every homeowner who asks me this.
1. Timeline tolerance. How long can you wait for real money? If the answer is less than 6 months, stop reading. Sell. The paperwork is simpler and the regret is smaller when you don’t have the patience to see a multi-year project through.
2. Risk tolerance. Can you absorb a scenario where the builder hits trouble, permits delay by 8 months, and you end up living in a rental for 30 months instead of 22? If the answer is “that would break me financially or emotionally”, sell.
3. Unit mindset. Do you actually want to own new strata units at the end of this? Or do you want cash? If the honest answer is cash, sell. Co-development is worth it primarily when you want the units — to live in, to rent, to give to family.
4. Counterparty discipline. Are you willing to spend $10K on your own lawyer reviewing every page of the term sheet and definitive agreement? If you’re going to sign whatever the builder’s lawyer puts in front of you, sell. The bad deals happen to owners who trust.
5. Tax and estate clarity. Do you understand (or are you willing to pay a CPA to model) the Principal Residence Exemption change-of-use, GST rebate eligibility, and capital gains on retained units? If not, sell or hire help before signing anything.
Four out of five “yes” answers means co-development is worth serious evaluation. Three or fewer means sell.
The Middle Path Most People Miss
There is a third option that gets ignored: sell to a builder at a premium with a retained unit clause. You sell the lot for market value plus a right to purchase one finished unit at cost. You get the clean sale and the upside on one unit.
This is harder to negotiate — builders prefer clean title — but on the right lot in the right market, it is the best of both worlds. See our deal structures guide for the mechanics.
What Actually Kills Co-Development Deals
Not market crashes. Not construction cost overruns. Not permit delays.
The single biggest killer is paperwork fatigue. Homeowners enter the deal excited, get worn down by 6 months of term sheets and lawyer letters, and sign something they don’t fully understand just to get it over with. Six months later, they realize the unit selection is “to be determined at builder’s discretion”, or the performance bond is actually a personal guarantee from a numbered company, or the waterfall pays the builder first.
If you can’t commit to reading every page of every draft with your own lawyer, don’t start. A bad co-development is worse than a clean sale at a lower price.
The Question I Ask Every Homeowner
“In 24 months, which regret would you rather live with — the regret of taking the cheque and watching units get built on your old lot, or the regret of spending two years in a paperwork fight to get units you’re not sure you really wanted?”
Your honest gut answer is the decision.
