How often can payments be made to a PACE lender?

The local authority will send out the tax bill that will contain a PACE amount due. The payment, unlike most other PACE jurisdictions, will go directly to the PACE lender or the Texas PACE Authority, if the property owner prefers. 
The tax assessor collector is only involved in case of default, and in sending out a notice of the PACE assessment with the tax bill. They do not collect any assessments themselves. 
Texas is the only state in the country that does not have the periodic PACE assessment payments collected with the tax bill. So the frequency of payments may be agreed upon between the Property Owner and the PACE Lender. However, at this time most lenders are expected to match the frequency of the payments with the tax bill.
