This worksheet is for estimation purposes only. CMHA is not responsible for the accuracy of the data if you remove the protection or alter any of the formulas. The accuracy of the calculation is entirely dependent upon the accuracy of the data entered. This worksheet calculates whether or not a tenant can afford a specific unit; it does not take Rent Reasonableness into consideration. Property owners could be asked to reduce the rent to comply with Rent Reasonableness requirements even if a tenant can afford the requested rent.
