A Korean reverse-mortgage estate decision starts with procedure, not a sale price
After a Home Pension subscriber dies, the family may need to preserve a surviving spouse's pension, repay the Korea Housing Finance Corporation settlement and retain the home, sell the home voluntarily with HF approval, or allow the mortgage or trust enforcement process to continue.
Those choices cannot be compared from the monthly payments received by the subscriber. The comparison needs the current HF-guaranteed loan balance, the collateral-home value determined under the relevant HF method, a separate supported market value, route-specific costs, timing, and available heir cash.
This calculator places three heir-settlement paths on one current-value basis: cash repayment and retention, an HF-approved voluntary sale, and court auction or trust public sale. It also places the surviving-spouse question before the estate comparison because Korean procedure can require action within six months after the subscriber's death.
The tool uses only the assumptions you enter. It does not retrieve an HF account, value the home, approve a sale, allocate co-heir shares, determine a trust beneficiary, calculate Korean tax, or decide whether inheritance renunciation or qualified acceptance is appropriate.
Treat an early result as a document request. Replace every estimate with written HF information, property evidence, transaction evidence, cost evidence, and case-specific legal and tax review before signing a contract, paying a settlement, or allowing a deadline to pass.
The three paths compared by the calculator
Comparison of direct repayment, voluntary sale, and auction or public sale after a Korean reverse-mortgage death| Path | Procedure assumption | Modelled net estate | Critical evidence |
|---|
| Repay and retain | Fund the HF settlement and clear the collateral | Market value less settlement, costs, and simple funding cost | HF values, heir liquidity, financing, ownership consent |
| HF-approved voluntary sale | Complete a normal-market sale within the HF-agreed process | Sale price less settlement, sale costs, and carrying costs | HF approval, achievable price, timing, closing mechanics |
| Auction or public sale | Court auction for mortgage collateral or public sale for trust collateral | Expected distributable surplus less separate heir costs | Comparable awards, priority claims, timing, statutory exceptions |
HF's death-procedure page states that an heir or the designated residual beneficiary may, with HF approval, sell voluntarily or repay in cash. A direct sale to a third party is to be settled within the agreed period. The page also describes a conditional period of up to three years where sufficient security and branch approval exist.
The calculator therefore permits a voluntary-sale assumption through 36 months, but the input limit is not an approval. The actual period, security condition, required documents, settlement account, and collateral release sequence must come from the responsible HF branch.
Build one dated evidence pack before entering figures
Four values that look like a home price can serve different purposes. The HF collateral value supports the settlement rule. A market value estimates the retained asset and provides a base for the public-sale recovery scenario. A voluntary-sale price reflects what can be achieved within the approved timetable and property condition. An auction or public-sale estimate reflects forced-sale evidence and process risk.
Record the source and date for each value. Keep a broker's verbal opinion separate from a written valuation, a portal asking price separate from a completed transaction, and an HF account figure separate from a family reconstruction of payments received.
Request from HF

- The collateral-home value applicable to direct or voluntary settlement
- Whether the contract uses mortgage collateral or trust collateral
- The surviving-spouse route, filing deadline, assumption documents, and ownership or beneficial-right steps
- Voluntary-sale approval, agreed period, settlement mechanics, and release documents
Confirm with the family and advisers

- Registration, legal, brokerage, clearing, financing, and tax cash amounts reviewed for each path
Step-by-step workflow
- Resolve the spouse pre-check first.
Select the collateral method and identify whether a spouse survives. If a spouse may continue the Home Pension, contact HF immediately rather than waiting for an estate-value comparison. Enter whole months since death only as a warning aid; the tool does not calculate a legal filing date from calendar days.
- Separate the balance, HF value, and market value.
Enter the written guaranteed balance and HF collateral value in their own fields. Use a separate, supported current market value for the retained-home and public-sale assumptions. Do not substitute the enrollment value, an online estimate, or cumulative monthly benefits for a current HF figure.
- Test direct repayment for both value and liquidity.
Enter immediately available heir cash, route-specific ancillary costs, the rate on any funding gap, and the number of months that funding would remain outstanding. The calculator applies simple interest for comparison. Reconcile it with an actual amortization schedule, principal repayment, lender fees, security, and eligibility before treating the path as feasible.
- Use an achievable voluntary-sale price.
Enter expected proceeds rather than one optimistic listing. Add brokerage, collateral release, clearing, legal, and separately confirmed tax. Monthly carrying cost continues for the assumed sale period. Compare the expected price with the displayed break-even price and investigate any required cash at closing.
- Treat auction or public sale as a scenario.
Enter an evidence-backed recovery percentage against market value, process costs deducted before distribution, separate heir-paid costs, and timing. Run low, base, and high recovery cases manually. The award price, priority claims, and date are uncertain and the model does not reproduce a court or trust distribution statement.
- Complete the six evidence checks deliberately.
The arithmetic remains visible before the checks are complete, but the interface does not label a leading path. That gate prevents an unsupported price from being presented as a recommendation. Even after all checks are complete, read the warnings and funding shortfalls before discussing a decision with co-heirs and advisers.
Formulas and interpretation
Applied direct or voluntary settlement
Applied settlement equals the lesser of the guaranteed-loan balance and the HF collateral-home value. If the HF value is lower, the calculator shows the difference as a settlement-cap difference.
This implements the structure described by the HF death-procedure guidance. The responsible branch's actual statement on the settlement date controls; the formula does not create a claim to a particular amount.
Repay and retain
Funding gap before interest equals settlement plus ancillary cost less available cash, floored at zero. Simple funding cost equals that gap multiplied by annual rate and months divided by twelve.
Net estate equals supported market value less settlement, ancillary cost, and simple funding cost. Future property tax, repairs, management, appreciation, rent, and a later sale are outside this one-date retention value and require a separate holding analysis.
HF-approved voluntary sale
Carrying cost equals monthly holding cost multiplied by voluntary-sale months. Net estate equals expected sale price less settlement, sale cost, and carrying cost.
Break-even sale price is the sum of settlement, sale cost, and carrying cost. If expected proceeds are below that amount, the model shows required cash. Available cash then determines the remaining shortfall, but closing mechanics may require funds earlier than this simple presentation suggests.
Auction or public sale
Expected sale price equals market value multiplied by the recovery percentage and rounded to won. Distributable proceeds equal that price less process cost and carrying cost, floored at zero.
Expected HF recovery is the lesser of distributable proceeds and the guaranteed balance. Expected surplus is any distributable amount above that balance. Net estate equals the surplus less separate heir-paid cost. This is a planning scenario, not a legal distribution calculation.
Worked synthetic example
The interface can load a synthetic example that demonstrates the formulas; it is not a Korean market average or an HF customer case. Assume a guaranteed balance of KRW 550,000,000, an HF collateral value of KRW 500,000,000, a supported market value of KRW 650,000,000, and KRW 100,000,000 of immediately available cash.
Direct repayment has KRW 15,000,000 of ancillary cost and funds the gap for twelve months at 5% simple interest. Voluntary sale produces KRW 630,000,000 after six months, with KRW 30,000,000 of sale cost and KRW 1,000,000 monthly carrying cost. Public sale recovers 80% of market value after twelve months, with KRW 20,000,000 process cost and KRW 5,000,000 separate heir cost.
Synthetic reverse-mortgage heir settlement results| Path | Expected net estate | Supporting result |
|---|
| Repay and retain | KRW 114,250,000 | KRW 535,750,000 total required cash |
| HF-approved voluntary sale | KRW 94,000,000 | KRW 536,000,000 break-even price |
| Auction or public sale | -KRW 5,000,000 | KRW 62,000,000 expected HF shortfall |
The applied direct or voluntary settlement is KRW 500,000,000, the lesser HF value. When all six evidence checks are complete, direct repayment leads the arithmetic comparison. It nevertheless has a KRW 435,750,000 cash shortfall against available cash, so funding feasibility remains a separate gate.
The public-sale shortfall is an expected HF recovery measure, not a declaration of personal heir liability. It triggers review of Article 43-4 exceptions and the actual estate facts.
A recovery shortfall is not automatically an heir's personal debt
Article 43-4 of the Korea Housing Finance Corporation Act generally limits the corporation's recourse for the covered claim to the collateral home. HF's consumer guidance accordingly explains that a shortfall is borne by HF while a surplus is returned to the heirs or the designated beneficiary.
The statute also contains exceptions. They include specified prior tax claims, priority wage and related claims, reverse-mortgage amounts paid after a termination event, and unrecovered loss connected with intentional or grossly negligent damage to the home. The exact statutory language and facts matter.
The calculator displays an expected HF recovery shortfall to explain the public-sale economics; it does not convert that shortfall into a personal-heir liability. If a shortfall appears, request HF's written position and obtain Korean legal advice on the statutory exceptions, priority claims, estate procedure, and any inheritance renunciation or qualified-acceptance deadline.
Surviving spouse and collateral method can change who should act
Six-month spouse review
Article 28-2 of the Enforcement Decree addresses an eligible spouse whose marriage continued from the guarantee agreement. For mortgage collateral, the subscriber's death can require the spouse to complete ownership transfer and assume the debt within six months, subject to the governing rules and HF process.
The calculator labels month six as still within the input-based review window and month seven as passed. That is a coarse warning, not a filing-date opinion. Contact HF immediately and use actual dates and documents.
Mortgage versus trust collateral
HF's comparison explains that mortgage collateral can require co-heir consent and ownership transfer for spouse succession, with residual property going to legal heirs after settlement. Trust collateral can permit a spouse to succeed to beneficial rights without inheritance registration, while the residual property follows the designated recipient in the trust arrangement.
Do not assume that ordinary statutory shares identify the person entitled to trust-sale surplus. Read the trust agreement and obtain HF and legal confirmation before giving instructions or signing a disposal document.
Decision scenarios
Retention has the highest value but heirs lack cash
A high net estate does not make direct repayment executable. Review total required cash, shortfall against available cash, actual borrowing eligibility, security, principal schedule, and how co-heirs would contribute. A co-heir who advances funds may also require a documented reimbursement or ownership arrangement.
The retained home continues to create tax, insurance, management, repair, vacancy, and sale risk. Model those future cash flows separately before concluding that the one-date retained value is superior.
Co-heirs agree to sell but disagree on price
Run conservative, base, and optimistic voluntary-sale prices while holding the evidence date constant. Extend the sale period and carrying cost in the conservative case. Compare each result with the break-even sale price and the cash needed if proceeds do not cover settlement and costs.
A higher listing price can destroy value when it lengthens marketing, misses an HF period, increases carrying cost, or leaves no funds for closing. Ask HF how approval, the purchase contract, deposit, final payment, settlement, and collateral release must be sequenced.
Auction or public-sale recovery looks very low
Do not lock one recovery percentage into the family decision. Use recent comparable awards, normalize property condition and rights, and run a range. Check whether process costs and carrying costs are deducted from the correct pool and whether a separate heir-paid cost is being counted twice.
Keep the expected HF shortfall separate from expected heir liability. Investigate priority claims and Article 43-4 exceptions with professionals instead of treating a general non-recourse description as a conclusion for the individual estate.
Interpretation mistakes to avoid
- Do not use cumulative Home Pension payments as the guaranteed-loan balance. Interest, guarantee charges, later payments, and account timing can make the HF figure different.
- Do not use the same unsupported number for HF collateral value, normal market value, voluntary-sale price, and public-sale price. Each serves a different rule or scenario.
- Do not apply a generic Korean tax rate. Tax can depend on inheritance date, basis, housing count, holding period, shares, deductions, actual expenses, and transaction form. Enter only case-specific cash amounts confirmed separately.
- Do not mark the evidence boxes merely to reveal a leader. Each box represents a document or professional review that should exist outside the interface.
- Do not interpret the highest net estate as legal authority to act. Ownership, co-heir consent, trust rights, spouse succession, estate procedure, funding, and personal housing needs remain separate decision gates.
- Do not allow the six-month warning to become a countdown substitute. HF should confirm the eligible spouse, actual start and end dates, documents, and completion requirements immediately.
Frequently asked questions
Must heirs repay the entire guaranteed-loan balance in cash?
HF's death-procedure guidance describes direct repayment and voluntary-sale settlement as the lesser of the guaranteed-loan balance and the current collateral-home value determined under the same valuation method used for enrollment. Obtain the actual HF figures; an online market estimate does not determine that settlement.
Does HF bear every shortfall when sale proceeds are low?
The general consumer explanation is that HF bears a shortage and the estate receives a surplus. Article 43-4 contains exceptions under which recourse beyond the collateral home may be possible. Confirm the actual account, payments, priority claims, property condition, and statutory facts before relying on the general rule.
Who receives a surplus after settlement?
For mortgage collateral, the residual generally follows the legal-heir structure after settlement. For trust collateral, the designated residual beneficiary in the trust arrangement matters. The calculator does not read a will, divide shares, resolve a dispute, or identify the entitled recipient.
Is the voluntary-sale period automatically three years?
No. HF guidance begins with settlement within an agreed period and describes a conditional maximum where sufficient security and branch approval exist. The responsible branch must confirm whether an extension is available, its length, collateral, documents, milestones, and consequences of delay.
Does the calculator determine Korean inheritance or capital-gains tax?
No. It deliberately does not infer tax status or apply a generic rate. Obtain path-specific amounts and payment dates from a qualified Korean adviser, then enter only the confirmed cash cost in the relevant field. Keep inheritance tax reserved cash out of the immediately available cash field if it cannot fund the settlement.
Can an overseas heir use this English page as legal guidance?
No. The page is an English planning aid for a Korea-specific product. Korean law, the Korean contract, HF's Korean documents, authority over co-heirs, notarization, apostille, remittance, tax residence, and representation may all require separate advice and original-language review.
Official sources and review scope
The statutory anchors were checked on September 2, 2026. The current Korea Housing Finance Corporation Act was law ID 009591, history master sequence 277275, effective January 2, 2026. The current Enforcement Decree was law ID 009656, history master sequence 281389, also effective January 2, 2026.
The implementation reviewed Act Articles 43-2 through 43-4, Enforcement Decree Article 28-2, HF's death procedure, its collateral-method comparison, and its inheritance-benefit explanation. These sources support the model boundaries; they do not eliminate the need to obtain the current account and case-specific branch decision.
Recalculate whenever a document changes
Begin with every evidence box unchecked. Use the first result to produce a request list for HF, co-heirs, the trustee documentation, brokers, auction specialists, legal counsel, and tax advisers. Record one evidence date and avoid combining a current balance with an old value or an undated cost estimate.
When the written evidence arrives, update the inputs and share not only the net-estate ranking but also the cash required, funding shortfall, sale-period assumption, expected HF recovery shortfall, spouse warning, and unresolved statutory issues. A decision is stronger when every participant is looking at the same scope and date.
