How long is a residual stock loan?

Usually short, from several months to around two years, because it is meant to last only as long as the sell-down. Renewal is at the lender's discretion and normally needs a fresh valuation. A developer planning its exit models what happens if sales take three or six months longer than expected, since capitalised interest and extension fees grow with every month the units stay unsold.

Is a residual stock loan the same as development exit finance?

They do the same job. Development exit finance is the term more often used in the UK, for a short loan that refinances a development loan at or near practical completion while the units are sold or let. Residual stock loan is the usual Australian and New Zealand name, and it is normally taken once some units have already settled and the rest are left. Terms, sizing and lenders vary in each market.

Can rent from the unsold units pay the interest?

It can help. Where units are let, lenders commonly expect the rent to service at least part of the interest, and capitalise the rest. But the rent is not the way out: the loan is still repaid from sales, and a lease that makes a unit harder to sell can reduce what the lender will advance against it. Where the developer means to hold the units, an investment loan is the better fit.

What happens if the units do not sell before the loan matures?

The developer can ask for an extension, which the lender may grant against a new valuation and a fee, or it can refinance, cut prices or sell the remaining units together to one buyer. If none of those clears the debt, the lender can enforce its mortgage and sell the units itself, usually for less than an orderly sale would have achieved. That is why the in-one-line value matters at the start.

Residual Stock Loan: How Lenders Size Unsold Units

The building is finished. The question is who still wants it.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED 2026-11-07

// THE SHORT ANSWER

A residual stock loan is what a developer reaches for when the building is finished, the construction loan is falling due, and some units have not sold. A new loan secured over the unsold units repays what is left of the construction debt, often at a lower margin, and gives the developer time to sell without cutting prices. The lender is no longer lending against a project; it is lending against stock the market has already passed over once at the asking price. So it sizes the loan on what the units are worth now, reads what they would fetch sold together, and takes each sale's proceeds as it settles.

// 01 — WHY A FINISHED PROJECT STILL NEEDS A LOAN

A construction loan is built to be repaid by settlements at completion: the presales settle, and their proceeds clear the debt. When some units are left over, the construction lender is still owed money on a project whose risk has changed. The building is finished, so the cost-overrun and completion risks have gone; what remains is the risk that the units will not sell at the prices the feasibility assumed. The construction lender priced and staffed the loan for the first kind of risk, and its term is ending.

The developer has three choices: cut prices and sell quickly, ask the construction lender for an extension, usually at a fee, or refinance the unsold units with a lender whose product is built for the second kind of risk. The name for that loan varies. Australian and New Zealand lenders call it a residual stock loan; in the UK, a similar loan taken at or near practical completion is often called development exit finance.

// 02 — HOW IT IS SIZED AND REPAID

Loan = advance rate × value of the unsold units

Release price = loan allocated to the unit × release factor

Loan after sale = loan − release price of each unit that settles

Which value is the main decision. A valuer can give each unit's value separately, sold one by one over a normal marketing period, and a lower in-one-line value, the price for the whole parcel sold to a single buyer now. Many lenders size on one and test against the other, and the advance rate depends on which basis it applies to, the location and how many units sit in one building. In Australia, where the developer accounts for GST on each sale of new residential property, lenders commonly measure against values net of that GST.

The loan is short, commonly a year or two, and renewal is not automatic. Interest is often capitalised on vacant units and serviced where units are let. Each settlement must pay a release price, typically set above the unit's share of the loan, so that the debt falls faster than the stock and the last units, often the hardest to sell, carry the least of it.

// 03 — THE EXAMPLE

An apartment developer, constructed for this page, has completed thirty apartments. Twenty-two have settled. Eight remain, listed at US$650,000 each, and the construction loan still owed is US$3.6m, due in two months. A residual stock lender instructs a valuation and offers 70% of the individual values, with a release factor of 115%. All the rates are the example's.

Price list, 8 units at 650,000 5,200,000

Valuation, individual, 8 at 600,000 4,800,000

Valuation, in one line 4,100,000

Loan at 70% of individual value 3,360,000

measured against in-one-line value 3,360 ÷ 4,100 = 82%

Construction loan to repay 3,600,000

Developer must find 240,000

Loan allocated per unit: 3,360,000 ÷ 8 = 420,000

Release price at 115% = 483,000

After four sales: 3,360,000 − 4 × 483,000 = 1,428,000

against four units at 600,000 1,428 ÷ 2,400 = 60%

The developer learns three things from the offer. The valuer has put the units 8% below the price list, so the market has spoken before any lender did. The refinance does not clear the old loan, and the developer must find US$240,000 or sell a unit first. And after four sales at valuation, the loan has fallen from 70% of the remaining value to 60%, because each sale repays more than its share. The interest added over the term, ignored here, works against that.

// 04 — HOW IT DIFFERS FROM AN INVESTMENT LOAN

Both are secured on finished property, and a developer holding unsold units may let some of them. The difference is the way out. An investment loan is repaid over years from rent, and the lender reads tenants, leases and interest cover. A residual stock loan is repaid from sales within a short term, and rent, where there is any, only helps with the interest; leases are often kept short so that units can still be sold with vacant possession.

A developer that decides to keep the stock long term has changed the loan it needs. The lender then has to underwrite it as an investment loan, on the income, and in Australia the change of intention can also have GST consequences for the developer. What it cannot be is a residual stock loan renewed year after year: a sell-down with no end in sight is an investment the lender did not approve.

// 05 — WHERE IT DECIDES A FILE

The first question is why the units are left. A few unsold units in a large project may be timing. A large share, or the same type of unit left in every block, says the product or the price was wrong, and the lender is being asked to finance the developer's hope that it was not. Presales that failed to settle add to the residual book in the worst way, because they are units a buyer once agreed to and then walked away from.

The second is what else the developer owes. A developer with residual stock in one project and a new project in construction may need the sale proceeds for both, and a lender asks whether its guarantees and cross-security reach the other project. In the Issue 08 file, the unsold townhouses at assumed prices are the second way out of the construction loan, which makes the residual stock lender's view of those prices a question for the construction lender too.
