Amazon has partnered with Realogy, the US's largest residential real-estate brokerage company, to launch a service called TurnKey that connects prospective homebuyers with real-estate brokers.

Customers who enter their details on Amazon.com are connected with Realogy brokers in the area where they're looking for a property.

If a person purchases a home through the service, they get up to $5,000 to spend on Amazon Home Services and Amazon's smart-home devices.

It's good for Amazon, which can get its smart-home devices into the hands of more customers and spread the word about the home services that it offers.

Amazon shoppers can now start the search for their next home on Amazon.com.

The tech giant has partnered with Realogy, the US's largest residential real-estate brokerage company, to create a service called TurnKey that links customers with real-estate brokers. People who use it to buy a property are then rewarded with a credit to spend at Amazon.

Customers who sign up for the new service on Amazon.com are asked to provide their details and the area where they're looking for a property and are then introduced to a real-estate broker in that area. Amazon simply provides the platform for the person to start the search.

If the person decides to purchase the house through TurnKey, Amazon gives them up to $5,000 to spend on Amazon Home Services — deep cleaning or repairs, for example — as well as smart-home products such as its Alexa devices.

The size of the credit depends on the cost of the house — to get $5,000, you'd need to buy a house that's more than $700,000.

The Amazon credit is covered by Realogy, which clearly sees value in having access to a large pool of Amazon customers who might be looking for a new house.

But Amazon also benefits from the service, helping it to put its smart-home devices into the hands of more customers and spread the word about the home services it offers.

"Customers can be overwhelmed when moving, and we're excited to be working with Realogy to offer homebuyers a simplified way to settle into a new home," Pat Bigatel, the director of Amazon Home Services, said in a statement.

"The Amazon Move-In Benefit will enable homebuyers to adapt the offering to their needs — from help assembling furniture, to assisting with smart home device set up, to a deep clean, and more."
