With a wise advertising strategy and utilizing existing features, Instagram Ads can be a very effective tool in influencing consumer buying interest and driving business growth. This research aims to analyze the use of Instagram Ads in an effort to increase interest in buying a house from PT Wengga Citra Jaya in East Kotawaringin Regency among generation Z. Generation Z's interest in buying a house is still relatively low due to several reasons and considerations. Generation Z are potential buyers in the future, so the low buying interest in generation Z must be overcome by carrying out marketing communication activities. The method used in this research is a qualitative method by collecting data through interviews with sources who are responsible for PT Wengga Citra Jaya's marketing activities and interviews with experts. The results of this research show that the efforts to use Instagram Ads carried out by PT Wengga Citra Jaya have not been optimal because there are elements that have not been used optimally.
