About this app

How much will it cost each month if I switch from Jeonse to monthly rent? Isn't this monthly rent too high by law?

Just like a calculator, simply press the numbers to instantly tell you the conversion amount and the legal limit.

✔ Jeonse → Monthly Rent

Example) If you convert a 300 million won Jeonse house to a 50 million won deposit → At a conversion rate of 4.5%, the monthly rent is approximately 940,000 won.

- Shows the total annual rent and whether it is within the legal limit.

✔ Jeonse → Deposit

Example) If you want to pay only 1 million won in monthly rent for a 500 million won Jeonse house → A deposit of 233.33 million won is required.

- View various cases at a glance with a table showing the deposit and monthly rent stages.

✔ Monthly Rent → Jeonse

Example) If you convert a house with a 50 million won deposit and 500,000 won monthly rent to a Jeonse → It is equivalent to a Jeonse of 183.33 million won.

- Find out which is less expensive: Jeonse loan interest or monthly rent. Comparison

✔ Check Conversion Rate (New Feature)

Example) If you propose a Jeonse of 300 million won with a deposit of 50 million won and a monthly rent of 1 million won → Conversion Rate 4.8%

- Immediately informs you if it exceeds the legal limit (Base Rate + 2%p, currently 4.5%)

- Calculates what the appropriate monthly rent would be (approx. 940,000 won) if the limit is met

- If the base rate changes, simply update the base rate column
