Stage 3 Stress DSR Imminent, How Much Will Mortgage Limits Decrease?
With the implementation of Stage 3 Stress DSR imminent later this month, mortgage limits for prospective home buyers are expected to be significantly reduced, causing a disruption in funding plans.

Key Summary: With the imminent implementation of Stage 3 Stress DSR at the end of this month, mortgage loan limits are expected to be significantly reduced in the second half of the year. Prospective home buyers urgently need to review their financing plans.
Stage 3 Stress DSR, What Changes?
According to financial authorities, the third stage of the 'Stress DSR (Debt Service Ratio)' loan regulation will be fully implemented at the end of this month. Following stages 1 and 2, the most stringent add-on interest rate (stress rate) of 100% will be applied, substantially decreasing the total mortgage limit available to borrowers compared to before.
Particularly, as Jeonse (lump-sum deposit lease) prices for apartments in the Seoul metropolitan area have been rising for 34 consecutive months, sparking fears of a continued rental crisis, this regulation is expected to heavily impact end-users considering switching from renting to buying. Concerns are also being raised that it might cool down real estate transaction volumes, which were slowly recovering on hopes of interest rate cuts.
Market Impact and Buyer Strategies
When Stage 3 Stress DSR is applied, the loan limit for a borrower with an annual income of 50 million KRW could decrease by tens of millions of KRW compared to the previous limit. Buyers who have already signed contracts or are awaiting final payments must urgently reconfirm their eligible loan amounts with financial institutions.
- Comprehensive Review of Financing Plans: It is essential to secure additional equity to cover the reduced loan limits.
- Utilization of Policy Mortgages: Buyers should actively check their eligibility for government-supported products like the Didimdol loan or special loans for newborns, which are relatively exempt from stringent DSR regulations.
