Aging out of rental acquisitions?

[John Brennan]

So if I’m in my mid fifties and want to retire within seven years. Are buy and hold rental properties a bad idea at this stage?

Even with fifteen year financing and with some cash flow from day one, equity payoff, appreciation and rental increases make it tough to envision that buying rental properties at this point are worth the effort compared with something like investing in syndications. 
At least this is my take. Anyone see this as flawed logic?

Thanks
