Prospert Inc., a company engaged in real estate tech and consulting, headquartered in Nagoya, Aichi Prefecture, with Osamu Takishita as Representative Director, has developed and publicly released a 'Free Asset Diagnosis Simulator Group (4 types in total)' that can be used completely anonymously and without membership registration by real estate owners and investors. Simultaneously, in collaboration with partner corporations, the company has begun offering a 'Direct Corporate Connection / Non-Public Route' for selling or restructuring assets without putting them on the market.
[Background of Development: Stricter Tax Rules and the Limits of 'Intuitive Investment']
In recent years, discussions surrounding the 'discrepancy between market price and appraisal value' in real estate inheritance tax valuations have become active. Following a Supreme Court ruling in 2022, there is a tangible risk that the National Tax Agency's 'General Rule 6' may be applied to schemes aimed at extreme tax avoidance.
It is no longer possible to simply trust sales pitches like 'high surface yield' or 'it will save you tax.' Real estate investment is 'business.' Asset owners and managers are now required to make cold, objective decisions based on concrete figures (data) such as location, appropriate rent, depreciation, loan interest, and 'how much remains in the account after tax.'
Therefore, our company has combined its real estate consulting expertise with system development technology to develop a dedicated group of simulators, enabling owners to quantify their current situation without anyone knowing and make the correct next move.

[Features of the Free Asset Diagnosis Simulator Group]
This suite of tools is provided completely anonymously, without membership registration, and free of charge, so that busy executives and asset owners can use it as a 'first step' before dedicating time to consideration.
1. Inheritance Tax Estimation Simulator
By simply entering the appraised value of your real estate and cash amount, you can instantly diagnose the estimated inheritance tax for yourself and your family, helping you with advance planning.
2. [Completely Anonymous] Real Net Proceeds Simulator
'If I sell now, how much will I actually have left?' This simulator supports all types of real estate, not just income-generating properties, but also private homes and undeveloped land. It accurately predicts the 'pure cash' remaining after deducting all expenses from the sale price, such as taxes, demolition costs, surveying fees, and loan repayments.
3. [For Investors] Income Property Real Sale Assessment Simulator
Based on Ministry of Land, Infrastructure, Transport and Tourism data and the income capitalization approach, this simulator calculates a realistic market price without revealing it to brokers. It also determines the risk level of a 'dead cross' due to expired depreciation.
4. [Investment Property] Purchase Simulator / Optimization Diagnosis
By simply entering the figures for a property under consideration, this simulator coldly diagnoses the 'true net proceeds' and 'investment recovery period,' and numerically determines the feasibility of purchase.

*Compatible with both PC and smartphones
[Next Step: Providing an Exit Strategy through a 'Non-Public Route']
As a result of objectively assessing the current situation with the simulator, 'selling' or 'restructuring assets' is often the optimal solution. However, owners then face the dilemma of 'wanting to dispose of it quickly, but not wanting to sell it cheaply.'
For customers who desire concrete action based on the diagnosis results, our company, in cooperation with partner corporations, offers a 'Non-Public, Direct Corporate Connection Route' that does not appear on general real estate markets (portal sites, etc.). This provides an exit strategy specialized for high-net-worth individuals, preventing the risk of information leakage and, depending on the conditions, enabling 'direct purchase and speedy settlement.'
Prospert Inc. will continue to support 'objective real estate business based on figures' that is not swayed by intuition or the convenience of brokers, contributing to everyone's asset protection.
