Product author: Vũ Hoàng
Ninh Hòa Invest AI helps families and small investors organize the messy early stage of researching land in Ninh Hòa. It brings local news signals, preliminary parcel checks, legal reminders, area profiles and personal notes into one mobile-first Android experience.
The app is intentionally built for people who are not comfortable with complex property software:
- Vietnamese-first copy with short, practical explanations;
- large touch targets and a clear six-item navigation with direct access to real-estate policy;
- no account, backend, paid API or sensitive Android permission;
- offline access to core legal-policy learning content;
- explicit separation between confirmed law, implementation roadmaps and research-stage policy.
The app supports information screening and learning. It does not make a buy/sell recommendation and does not replace official verification or professional legal advice.
V34.1 gives the Chính sách BĐS mới module a dedicated sixth bottom-navigation destination and adds an official planning-news format. The underlying V34 module translates major real-estate policy changes into plain Vietnamese. Every topic follows the same decision-friendly structure: what it means, who may be affected, why it matters, what to verify next and the current legal status.
| Status shown in the app | What it means |
|---|---|
| Đã có hiệu lực | A legal basis is in force; the exact application still depends on the case. |
| Theo lộ trình | The legal framework exists, while implementation or data rollout is continuing. |
| Đang nghiên cứu | A proposal or policy direction — not an obligation already applied nationwide. |
| Cần kiểm chứng nguồn địa phương | Users must check current Khánh Hòa and Ninh Hòa instruments. |
- the removal of the national land-price framework and the newer local land-price-table mechanism;
- tighter conditions around project land subdivision and the distinction from household parcel splitting;
- transaction-price transparency and the risk of two-price contracts;
- research-stage policy on second-property or unused-property taxation;
- housing and real-estate market information databases;
- holding cost as a combined financial risk, not a made-up universal tax.
Users select their role, number of properties, cash-flow status, debt level and investment goal. The app returns:
- a 0–100 screening score;
- a plain-language pressure level;
- three main warnings;
- three practical next checks;
- a Save to Notebook action backed by LocalStorage.
This score measures exposure to policy-sensitive investment behaviour. It is not a tax calculation or legal conclusion.

The product deliberately stops before the final transaction decision. Its job is to help users ask better questions before visiting land, paying a deposit, changing land use or declaring tax.

Ninh Hòa Invest AI is an educational information-screening and personal note-taking tool.
Before buying, selling, paying a deposit, changing land use or declaring tax, users should verify the latest official instrument and consult the relevant land-registration office, tax authority, notary, lawyer or other qualified professional.
This app is not legal advice, valuation advice or investment advice. Scores and explanations are not official conclusions.
Added a legal policy intelligence module that explains real estate regulation changes in plain Vietnamese, separates confirmed law from draft/research-stage policy, and helps users estimate policy pressure for speculation-heavy investment behavior.
This project demonstrates product discovery, Vietnamese UX writing, mobile information architecture, risk-aware LegalTech communication, offline-first state management, Android WebView engineering and automated APK delivery.
