Old House on a Multiplex Lot: Sell to a Family or Builder?

5 min read

A family prices the house and a builder prices the land. Desiree McNulty of The Donum Group explains how to tell which one will pay more for an older Vancouver house, and how to compare their offers.

Key takeaway

An older Vancouver house on a lot that allows a multiplex can sell to a family, who prices the house, or to a builder, who prices the land as the sale value of the homes it allows less build cost, City fees, interest and profit.

VanPlex's 2025 model of every eligible R1-1 lot in Vancouver found most did not show a builder profit, so the owner should run the lot's proforma first, compare it with recent house sales, market to both buyers when the two are close, and compare offers on price, deposit, conditions, completion date and rent-back.

What this covers

  • selling to a builder vs a family
  • how builders price land
  • lot checks before a sale
  • comparing offers
  • co-development as an alternative

If you own an older house in Vancouver, two kinds of buyer may want it. A family buys the house to live in. A builder buys the land to tear the house down and build a multiplex. They look at the same property and price it in different ways. I’m Desiree McNulty, a REALTOR® with The Donum Group at Oakwyn Realty, and before you list, my advice is to find out which of the two will pay you more.

Sometimes it’s the builder. Often it’s the family. You can work out which before the sign goes up.

Two buyers, two ways to price the same lot

Two buyers for an older house: a family pays for the house, meaning the rooms, the condition, the school and the yard; a builder pays for the land, meaning the homes the lot allows, less the cost to build them and a profit

A family prices the house. They look at the kitchen, the number of bedrooms, the roof, the school catchment and the yard. They compare it with other houses for sale nearby.

A builder prices the land. The builder starts from what the finished homes will sell for. Then they take away the cost to build, the City’s fees, the interest on the loans, and the profit they need for the risk. What’s left is the most they can pay for your lot. The condition of your kitchen doesn’t count, because the kitchen is coming out.

So a house in good shape on an ordinary lot suits a family buyer. A tired house on a lot that suits a multiplex may get more from a builder. VanPlex explains how builders read a lot in this post on how multiplex buyers price land.

Most lots don’t make a builder money

When VanPlex modelled every eligible R1-1 lot in Vancouver in 2025, with real build costs, fees, financing and resale prices, most of them did not show a profit for a builder. You can read the full model and its method.

Your lot may still be one that works. Check it before you assume a builder will pay more because the zoning allows a multiplex.

How to find out which buyer pays more

Run the builder’s numbers yourself, before anyone makes you an offer. Enter your address on the VanPlex home page and the proforma shows how many homes your lot allows, what they would cost to build and what they would sell for. It tells you whether a multiplex on your lot makes money, and so how much room a builder has to pay for the land.

Then compare it with what a family would pay for the house. Your REALTOR® can show you recent sales of similar houses nearby.

A builder also checks things a family may never look at:

  • the lot’s width and depth, and whether it has a lane
  • whether the lot slopes
  • large trees the City may not let them remove
  • whether the house is on the City’s heritage register
  • the sewer and water connections the new building will need

VanPlex lists eight checks that stop a multiplex before the math starts. If your lot fails one of them, a family is your buyer, and you can price and market the house for them.

Market to both if you’re not sure

If the numbers are close, I’d market to both. That means a listing that does two jobs.

For the family: good photos of the house, the yard and the street, and the school catchment.

For the builder: the lot dimensions, the zoning, whether there is a lane, and any survey you have. A builder looks for the lot size and zoning first, so make sure those fields on the listing are filled in.

When both kinds of buyer show up, they compete, and that helps you on price.

Compare the whole offer, beyond the price

Offers from the two kinds of buyer often look different on paper. A builder’s offer may come with longer conditions, because they need time to check the lot with the City and to line up financing. They may ask for a later completion date, or offer to let you stay in the house and rent it back until they’re ready to build.

So I put every offer side by side:

What to compareWhy it matters
PriceThe obvious one
DepositA larger deposit gives the buyer more to lose if they walk away
Conditions, and how long they lastYour house is off the market while the buyer checks
Completion dateWhen you get your money, and when you must move
Rent-backWhether you can stay after the sale, and for how long

A higher price with three weeks of conditions can be worth less to you than a firm offer from a family. My job in a negotiation is to make those trade-offs plain, so you choose with all of it in front of you.

Other choices besides selling

If your lot does work for a multiplex, you have more options than selling to a builder. Some owners partner with a builder and keep one of the new homes. Some sell together with the neighbour next door. VanPlex has a guide to co-development and a frank take on co-developing versus selling. Talk to your accountant too, because each choice can be taxed in a different way.

Steps for selling an older house that might suit a multiplex: before listing, run the numbers for your lot; on the listing, describe both the house and the lot; when offers come, compare price, deposit, conditions and completion date; during conditions, the builder checks the lot; at completion, you are paid and hand over the keys

Before you list

  1. Run the proforma on your address and see whether a multiplex makes money there.
  2. Ask for recent sales of similar houses to see what a family would pay.
  3. Check the lot against the eight blocking conditions.
  4. If the two numbers are close, write the listing for both buyers.
  5. Compare every offer on price, deposit, conditions and completion date.

Frequently asked questions

Will a builder pay more than a family for my old house?

Only when a multiplex on your lot makes money. A builder can pay for the land only what is left after the cost to build, the City's fees, interest and profit. When VanPlex modelled every eligible R1-1 lot in Vancouver in 2025, most did not show a profit for a builder, so check your own lot before you assume.

How does a builder decide what to pay for a lot?

The builder starts from what the finished homes will sell for, then takes away the cost to build, the City's fees, the interest on the loans and the profit they need for the risk. What is left is the most they can pay for the land. The condition of the existing house does not count, because it is coming down.

What does a builder check before buying a lot?

The lot's width and depth and whether it has a lane, whether it slopes, large trees the City may not let them remove, whether the house is on the City's heritage register, and the sewer and water connections the new building will need.

How do I compare a builder's offer with a family's offer?

Put them side by side on price, deposit, the conditions and how long they last, the completion date, and whether you can rent the house back after the sale. A higher price with weeks of conditions can be worth less than a firm offer.
