When quoting a yield of a transaction e.g. yield 3.8% behind the yield it is quote "factor" - in this case of a yield of 3.8% it is mentioned in brackets (factor 26.11) . The lower the yield the higher the factor. How does one calculate the factor and what does it mean? In a calculation regarding a property sale and although the calculation is understood I still don't understand what "factor" means, I don't mean the word but the meaning in this context what relation has this to the yield or why the calculation of the factor?
