You know markets are getting frothy when you start to see new entrants piling in. This is what we are beginning to see with the mortgage REIT market. Investor demand for mortgage REITs such as Annaly Capital Management ( NLY ) and American Capital Agency ( AGNC ) has increased due to the low absolute rates available in other income products, such as fixed income, dividend paying common stock and traditional REITS. Naturally, where there is demand, there will be supply. Let's meet the new kids: Ares Commercial Real Estate Corporation ( ACRE ) is a specialty finance company that originates, invests in, and manages middle-market commercial real estate loans and other commercial real estate investments. Through its national direct origination platform, Ares Commercial Real Estate provides financing for middle market borrowers. (See its IPO prospectus here .) AG Mortgage Investment Trust ( MITT ) Is the oldest of the new kids on the mREIT block as it's nearly one year old.
