Buying a Malaysian property gives you an asset, not a right to live in the country. Residency runs through a separate programme, most commonly Malaysia My Second Home.
MM2H was restructured into tiers, and the current shape pairs a fixed deposit with a minimum property purchase: a Silver tier from around USD 150,000 on deposit with a property from about RM600,000 and a five-year renewable visa; a Gold tier from around USD 500,000 with a property from about RM1,000,000 and a longer renewable term; and a Platinum tier from around USD 1,000,000 with a property from about RM2,000,000 and the longest term. A separate, cheaper route exists tied to the special economic zone in Johor, where the qualifying property must be bought from a designated developer.
These requirements have been revised more than once, and the fine print — dependants, age bands, medical cover, minimum days in country — moves with them. Treat the numbers above as the shape of the programme rather than the final word, and confirm the current criteria before you plan a purchase around a visa.
