How much extra cash would a delayed sale require?

Suppose a household closes on a new home, pays an extra 1,500,000 won a month in interest and building fees until the old home sells, and spends 2,000,000 won in one-time moving costs. Owning both homes for 3 months costs an extra 6,500,000 won. For 6 months it costs 11,000,000 won. A delay of 3 months adds 4,500,000 won even if the sale price stays the same. If the household was counting on sale proceeds to close on the new home, calculate the funding gap on closing day separately from carrying costs.

Check for yourself

  1. If interest and building fees are due on different days, when is available cash lowest?
  2. If the sale contract is signed but the final payment is late, how long would ownership of the two homes overlap?

Limits of application

This hypothetical calculation assumes a constant sale price and monthly carrying cost. Check principal payments, taxes, brokerage fees and financing availability separately.

What to look for
See what area indices, price gaps between new and older homes, and transaction frequency in a complex can each show.
Why it matters
Once the new home’s closing date is set, calculate how much additional cash and carrying cost a delayed sale of the existing home would require.

Timeline

9 segments
  1. The guest suggests asking both whether a home suits the buyer and whether it can be sold when it is time to move. Contracts for comparable units in the same complex and the gaps between those contracts are more direct evidence than area-wide volume. Separately calculate the extra cost of holding the current home if its sale is delayed.
