Apartment purchases in more than 100 Brisbane suburbs, circulated on a confidential list, will face new lending restrictions from next Monday from the home town lender, Suncorp.
The list covers 39 Brisbane postcodes.
Under Suncorp's new rules, it will no longer accept investment loan applications for apartments where the buyer does not have a minimum deposit of 20 percent or more.
The exceptions are existing home loan applications and those received before Friday.
"Our settings have been adjusted for postcodes based on recent weakness in the investment unit market in Brisbane, with evidence of a reduction in prices," a Suncorp Bank spokesman said.

The Australian Financial Review who obtained the list reports developers, such as Consolidated Properties, claim Brisbane has been cruelled by restrictions on financing set up to ease speculative apartment buying in Melbourne and Sydney.
Suncorp is a Brisbane based top 20 ASX-listed company with $97 billion in assets which employs 13,400 people and serves close to nine million customers across Australia and New Zealand.
It commenced business in 1916 as the State Accident Insurance Office.
The RBA has repeatedly warned buyers of the likely oversupply in Brisbane apartments.
Last week the bank noted to date, the adjustment in the Brisbane apartment market has not resulted in significant stress.
"Settlement failures appear to have remained in line with historical norms, although the peak of new supply is yet to come.
"Some developers, however, report that tighter financing conditions are contributing to delays in the settlement of off-the-plan purchases, as valuations below the purchase price reduce the amount banks will lend.
"In liaison, industry participants and banks express confidence that the Brisbane market will continue to absorb the new supply despite tighter financing conditions for buyers.
"Continued weakness in rents, and so rental income, remains a debt-servicing risk for investors," the RBA said.
