Exit Strategy for Retiring Landlords

[Toyosi Ogunkua]

First-time poster. My wife and I are new investors, looking to buy single-family or small multi-family in the Northern suburbs of Fort Worth. In the 7-habits of highly effective people, Steven Covey states you should start with the end in mind. My question is for landlords who are "retiring" from the real estate investing or approaching that point in the next few years. What is the exit strategy for someone who has built a portfolio of 20 or fewer units, and wants to retire from the business?
