Not really. But managed to find tenants

with 700 credit scores. My friend also did. Maybe the difference is the locations of the rental houses? "credit score only tells past result, future performance is never guaranteed." This is true and that's why I asked in my post if those troublesome tenants have good credits.

Honestly if "CD or money marke" offer 3%+ interests I'd not go my way out to invest anything else. But they are far from keeping with inflation.
