Bad to keep just one rental?

[Account Closed]

I currently own one rental. I buy through turnkey providers, so I am looking at properties listed above market price. Prices have risen so now the cash-flow with these properties aren't that great anymore (if there are any).  I want to scale so that if this property goes down, I can have the others pick up the slack. At the same time, I don't want to be picking up properties that don't cash flow.

My rental is a very old home (built in 1910), and I am expecting to see problems. I have funds ready to invest, but am considering putting them in REITs or syndications instead. Should I be looking to offload this rental I own, or continue to hold on?

BTW, I get financing on my properties, which is why it's hard for me to find cash-flowing rentals.
