What it means
A short sale happens when a property is worth less than the loan secured on it, a position often described as being underwater or having negative equity. The owner cannot sell for enough to clear the debt, so the lender must approve the sale and agree to accept the shortfall.
Without that approval, the sale cannot proceed. Lenders agree because a foreclosure is slow and expensive.
They face legal fees, months of unpaid interest, the cost of maintaining an empty building and often a lower price at auction. A short sale can recover more cash in less time, which is why many lenders prefer it.
The process starts with the owner showing financial hardship and submitting documents. The lender then reviews the offer, often commissioning its own valuation, and may counter.
Approval can take weeks or months, and a buyer must be willing to wait. The owner should not assume the remaining debt disappears.
Depending on local law and the terms of the agreement, the lender may waive the shortfall, known as the deficiency, or it may pursue the owner for it. There can also be tax consequences if forgiven debt is treated as income, so advice from a qualified tax adviser matters.
For buyers, short sales can offer bargains but they come with delay and uncertainty. For investors and finance teams, they are a marker of stress in the property market.
A rise in short sales often signals falling prices and tightening credit. For anyone advising a client on a short sale, the sequence matters.
The seller should obtain the lender's written approval of the exact price and terms, confirm in writing what happens to any deficiency, and only then agree to close. Skipping any of these steps can leave the seller owing money after the keys have changed hands.
In practice
Real-world examples.
Example
A couple bought a flat for $400,000 with a small deposit, and prices then fell 20%. When one of them loses a job, they list the flat at $320,000, still below their $370,000 mortgage. The lender approves the sale to avoid the costs of repossession.
Example
A small business owner personally guaranteed a loan secured on a rental property. Rents dropped and the property is worth $150,000 less than the debt. The owner negotiates a short sale and also asks the lender to waive the deficiency in writing.
Example
An investor spots a short sale listing priced 15% below nearby sales. She submits an offer and then waits seven weeks for the lender's approval. She uses the time to arrange her financing so she can complete quickly once approved. She also builds the extra repair costs into her budget, since short sale properties are often sold in poor condition.
Formula
Calculation
Deficiency = Mortgage balance - Net sale proceeds received by the lender
Suppose an owner owes $320,000 and the home sells for $280,000. Agent commission at 6% is 280,000 x 0.06 = $16,800, and other closing costs are $3,200. The net proceeds to the lender are 280,000 - 16,800 - 3,200 = $260,000. The deficiency is 320,000 - 260,000 = $60,000, which the lender must either write off or try to recover from the owner.Case study
Seen in the real world.
Oakhaven Properties is an illustrative, fictional investment company that owns a small apartment building financed with a $1,200,000 loan. Occupancy falls after a local employer closes, and the building is now valued at only $950,000.
The company asks the lender to approve a short sale. The lender calculates that foreclosure would cost about $90,000 in fees and months of lost interest, and agrees to accept a buyer's offer of $940,000.
The net proceeds after costs leave a deficiency, and Oakhaven negotiates a written waiver of most of it. In this illustrative case, the finance director learns to get the waiver in writing before closing, since a verbal assurance would not protect the company. The company's accountant also records the loss on disposal in the period of sale and checks whether any forgiven debt must be reported.
Watch out
Common mistakes.
- Assuming the remaining debt is automatically cancelled once the short sale completes.
- Listing the property without lender approval, which can delay the deal or cause it to fall through.
- Ignoring the possible tax on forgiven debt, which depends on local rules and the circumstances.
Questions
People also ask.
How long does a short sale take?
It often takes several months because the lender must review hardship documents, value the property and approve the offer.
Is a short sale better than foreclosure for the owner?
It is often less damaging to a credit record and gives more control, though the exact effect depends on the lender and local law.
Who pays the sale costs in a short sale?
The lender usually accepts that sale costs come out of the proceeds, which reduces the amount it receives. That is why the lender looks at net proceeds, not the headline price, when it decides whether to approve.
