A St.George spokesperson said the bank continually reviews its products and services to ensure they meet the requirements of its customers.

"In order to simplify and streamline our self-managed super fund products, we will be withdrawing from sale our SMSF Home Loan product and Business Lending to SMSFs, effective Tuesday 31 July 2018," said a St.George spokesperson.

The bank confirmed it will "continue to service and support its existing customers".

This decision follows similar moves by other banks in recent years, with NAB announcing in 2015 that it would no longer offer loans to SMSFs for residential properties.

Most of the main lenders in the SMSF property loans space have continued to tighten lending policies for SMSF property loans in recent months, particularly in relation to the minimum assets required and the type of properties they will accept as a security.

Some lenders are worried about the current off-the-plan buying environment, particularly in Sydney and Melbourne where property prices are starting to drop, Your Welcome Finance director Chris Straw told SMSF Adviser previously.

Mr Straw said they are also looking to see that an SMSF has a certain balance in their fund and liquid assets outside of the property that’s being purchased.

“There are some minimum asset requirements where they’ve got to have a couple of hundred thousand dollars in the SMSF,” he said.

H&R Block also recently found that some clients who over-committed during market highs, or locked themselves into off-the-plan purchases, are running into troubles as lending conditions tighten and tax concessions are phased out.

“There’s been a lot of tightening in the lending world with the banks. In fact, some have dropped out of the market altogether when it comes to lending to SMSFs,” said H&R Block SMSF director Kimberlee Brown.
