Student Rental Investment Market

I'm curious of the current market demand for student housing and appeal to rental investors. I've owned 2 houses in College Station/Bryan (Texas A&M University) for 8 years. I'm a retired engineer and have been successfully using income from these houses to support my retirement without dipping into retirement savings.

I'm transitioning my business from rentals to a franchise and would consider selling one of my houses (5 br/4 ba - the other houses my son while he's still attending). These homes were built in 2016/17 and I've managed/maintained them myself. They have been the best investments I've ever made, but hoping to have greater cash flow influence with a daily business model.

Is there demand for these types of rentals in the investment community?
