CNN just released the article linked above. All the sudden relators are posting about being able to get 0-0.25% interest rates. The article says the fed are "willing" to go into the negative if necessary. As a relatively new investor (2 SFH rentals, 1 live in flip) I'm curious to hear the thoughts and strategies of seasoned investors regarding all this.
