According to my research on real estate value estimators, I can say that based on the information provided within the question the term being described is called the Gross rent multiplier. This is defined as the number of years the property would take to pay for itself in gross received rent. This can only provide a really rough estimate because many things need to be taken into account such as the fact that not every month will have tenants paying rent and also the fact that some of the money will go to repairs.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
