Just to clarify JASA owes $220k wouldn't the yield be calculated on what Jasa owes? Makes it nearly 9% yield?
I would calculate yield based on market value of the property to compare to other potential investments, not what is owed on it. Market value is what he could sell it for, and he could put these proceeds into another investment that yields better. Although obviously, have to take into account buying and selling costs. Otherwise you could have a $1M property, owe $100K, receive rent of $20K per year and call it a 20% yield?
