Calculating cleaning fee for budgetinga STR?

[Michael Trueba]

Hi everyone! I'm creating an excel sheet to help calculate whether properties are more or less likely to be profitable for STR. I hit a wall for cleaning services, how can i calculate the monthly service fee when budgeting because in my area it depends on the size and i dont have any property yet to use as a reference. My market as a cleaning fee average of 150 per booking so i have that from my research.

Thanks in advance!
