Step 3 Cash shortfall with high Real Estate concentration → in-kind vs. installment payment decision

Problem

Even when a person in their 60s calculates inheritance tax at ~$75,000–375,000, if 70–80% of assets are in Real Estate, the heirs (children) lack the cash to pay the tax. Deciding whether property-in-kind payment, installment payment over 5–10 years, or property sale is the best strategy requires a tax consultant (costing ~$375–750), and there's no tool to compare scenarios beforehand.

Solution

Enter the decedent's asset list (Real Estate assessed values, financial assets, insurance proceeds) on the web, and the system calculates the estimated inheritance tax, then displays a comparison table of three payment methods (lump sum, property-in-kind payment, installment payment) with real costs for each scenario (interest, appraisal fees, distressed sale discounts, etc.). It identifies the cash shortfall and provides specific solutions (insurance proceeds utilization, optimal property selection for in-kind payment, etc.).

Target: Ages 55–68, assets with 70%+ Real Estate concentration, in the process of Estate planning but lacking a payment source strategy, household asset manager
Revenue Model: Free basic simulation (payment method comparison), ~$9.00 Per Transaction for detailed Report (optimal property selection for in-kind payment + installment interest calculation + insurance utilization strategy)
