I understand there is no fee for registering. Should I lease a residence in a building or complex shown to me within 90 days of such showing, I agree to pay a commission of 15% of one year's rent or 1 months rent depending upon what was agreed upon. This commission is earned and payable when I sign a lease and/or the landlord gives its approval for said residence. If there is any issue with collecting the brokers fee and it has to be litigated in court, the fee will be 15% plus any legal fees accrued.
