According to Notification No. 15/2017 (the Negative List), foreign investment in the construction of and real estate investment in residential buildings is subject to joint-venture with Myanmar citizen/enterprises. The list does not prohibit nor imposes other explicit discriminatory conditions on the investment by foreigners in other types of real estate assets, notably land and commercial/industrial building [some activities require approval from the relevant Ministry]. Despite this, the Myanmar Investment Law (Art. 50), specifies that foreign investors [i.e. where foreign shareholding exceeds 35%] may only lease land or building for up to 50 years after obtaining an Permit (if the investment is subject to MIC Permit) or Endorsement (for all other investments) by the Myanmar Investment Commission. Otherwise, foreign investors are only allowed to lease land for up to one year according to the Transfer of Immovable Property Restriction Act 1947. Therefore, it is assumed that foreign investment in land is limited to 35% and residential real estate is allowed  thourgh joint venture with citizen investors, and no such restriction applies for commercial real estate assets.
