Core Viewpoint - Real estate investment trusts (REITs) can provide significant dividend yields, with AGNC Investment and Healthpeak Properties being highlighted for their monthly dividends, but their sustainability and growth potential differ significantly [1]. Group 1: AGNC Investment - AGNC Investment is a mortgage REIT that invests in Agency MBS, which are protected against credit risk by government agencies, and it employs leverage to enhance returns, resulting in a high monthly dividend yield of 15.7% [3]. - The CEO noted that the outlook for agency MBS investments remains favorable, with potential returns in the low-20% range, which exceeds the company's total cost of capital of approximately 18% [4]. - However, AGNC has previously cut its dividend when returns fell below costs, indicating that it may not be the best option for investors seeking a highly sustainable income stream [5].
