Investment yield.
When you buy property to let, this is where you judge whether the price is right. Rent and purchase price alone do not give the answer. Vacancy and the loan rate change the yield decisively.

Where to start
Property Investment Yield
Cap rate, pre-tax cash flow and return on equity on one screen. The three say different things, so they need to be read together.
If the cap rate is below the loan rate, every extra won borrowed loses money
Borrowing only lifts returns when the cap rate is above the loan rate. Below it, the more you borrow the lower your return on equity. For logistics warehouses around Seoul in 2026 the gap between the two is small, so without calculating it is easy to get the direction wrong.
Not in this group
- Residential rental yield
- What is here covers logistics and commercial property. Homes carry a separate rental income tax that changes the calculation, so read it with the Rental Income Tax Calculator under Owning.
- Loan limits when buying with a loan
- That is Loans. How much you can borrow has to be settled before return on equity is.
- Capital gains tax when you sell
- That is Selling & Inheritance. Deciding on the holding-period yield alone lets tax at the exit eat the return.
The law this group rests on
