What it means
When you buy a house or flat to live in, you are an owner-occupant. If you buy the same property to rent it to tenants, you are an investor.
Lenders care about the difference because people are generally less likely to stop paying the mortgage on the home they live in. Because the risk is lower, owner-occupant loans typically come with better terms.
These can include lower interest rates, smaller minimum deposits, higher borrowing limits and sometimes access to government support schemes for homebuyers. Investor loans usually cost more and need larger deposits.
Declaring owner-occupant status is a serious matter. A buyer usually signs a statement that they intend to live in the property for a minimum period, and lenders can ask for evidence such as address records.
Claiming to be an owner-occupant to get a cheaper loan, when the plan is to rent the property out, can count as mortgage fraud. Tax and insurance also differ.
Many countries give owner-occupants relief on the sale of their main home and different treatment on property taxes, while an investor pays tax on rental income. An insurance policy for an owner-occupied home is not the same as a landlord policy, and the wrong cover may not pay out.
The status can change. If an owner-occupant moves out and rents the home, they must usually tell the lender and the insurer, and the loan terms may be adjusted.
Rules vary widely between countries and lenders, so the contract must be read carefully. Property valuations matter to the lender because the home is the security for the loan.
The lender will usually commission a valuation, and the loan to value ratio is based on the lower of the price paid and the valuation.
In practice
Real-world examples.
Example
A young couple buys a two-bedroom flat for $350,000 and moves in the following month. They qualify for a lower rate than an investor would receive. They sign a declaration that the flat is their main residence.
Example
A landlord owns three rental properties and decides to move into one of them. After notifying her lender and insurer, she becomes an owner-occupant of that property. She discusses whether she can switch it to a residential mortgage with a lower rate.
Example
A buyer purchases a home with a loan that requires owner-occupancy for twelve months. After four months he takes a job overseas and rents the house out. The lender discovers the change, and he has to negotiate to avoid being forced to repay early.
Formula
Calculation
Housing cost ratio = monthly housing payment / gross monthly income
Loan to value = loan amount / property value
A buyer earns $8,000 a month before tax and buys a home for $400,000 with a $340,000 mortgage. Monthly mortgage payment, including property tax and insurance, is $2,400. Housing cost ratio = 2,400 / 8,000 = 0.30, or 30%. Loan to value = 340,000 / 400,000 = 0.85, or 85%, which means the buyer has paid a 15% deposit of $60,000.
Reading the result: many lenders prefer a housing cost ratio below about 30% to 35% of income and look more closely at loans above 80% of the property value. As an owner-occupant the buyer may be able to borrow at 85% of value, while an investor buying the same home might be limited to a lower proportion.
A buyer can also test the position with a stress check. If interest rates rose by 2 percentage points and the payment went up to $2,900, the housing cost ratio would be 2,900 / 8,000 = 36.25%, which shows how much room the household has before the mortgage becomes a strain.Case study
Seen in the real world.
Linden Park Lending is an illustrative, fictional mortgage lender that offers a rate 0.75 percentage points lower to owner-occupants. During a review, the credit team found that a number of loans had owner-occupant status but showed rent payments from tenants at the same address.
The team wrote to the borrowers and asked for confirmation of their living arrangements. In several cases the owners had moved out for work reasons and had not told the lender, and the lender moved the loans to investor terms.
On a $300,000 loan, the extra 0.75% adds 300,000 x 0.0075 = $2,250 a year in interest. The illustrative lesson is that honest declarations protect both sides, and that status should be checked again when circumstances change.
Watch out
Common mistakes.
- Claiming owner-occupant status to get a cheaper loan when the real plan is to rent the property out.
- Moving out and renting the home without telling the lender or insurer.
- Assuming that a holiday home counts as owner-occupied, when it is usually treated as a second home with different terms.
Questions
People also ask.
How long must I live in the property?
It depends on the lender and the product, but a minimum period of around twelve months is common.
Can I rent out a room and still be an owner-occupant?
Often yes, if the property remains your main home, though the lender may need to approve it.
Why do lenders offer better rates to owner-occupants?
Because borrowers are generally more committed to paying the mortgage on the place they live, so the risk of default is lower.
