It used to be a single family rental was a good deal if it was priced at 10-12 times annual rent, multi-unit (+4) low rent buildings needed to be priced at 8-10 times rent, but condos have always had the worst ratio due to hoa fees and less appreciation.
Even if prices were stable for the next few years rentals don’t make sense with current ratios. SFR’s currently are over 20x annual rent. Likely it will take at least 5 years of a combination of declining prices and increasing rents before investment numbers pencil out.
