An eligible borrower shall, with the approval of the commissioner, fix rates to be charged for occupancy or other use of each project. The commissioner upon his own motion, or upon application by the eligible borrower or lienholder may vary the amount of such charge from time to time so as to secure, together with all other income of the eligible borrower pledged, assigned or otherwise made available to the agency, sufficient income to meet, within reasonable limits, all necessary payments by the said eligible borrower of all expenses, including fixed charges, sinking funds and reserves.
