How to Pay a Contractor Long Distance

[Chivas Miho]

Hi BP, I recently went through a fairly large renovation project on a duplex meant to be a buy and hold property.   The rehab occurred as a long distance property in Michigan where I live in Hawaii.  My property manager agreed to act as a Project Manager and coordinate all the Contractors through the rehab process for a fee.  The problem I had during this process was keeping the Project Manger funded since she was paying the contractors and suppliers.  To avoid added processing fees, we decided to use Paypal as a payment method and send funds back and forth.  The issue I have with this is that I would need to send funds via Paypal early so that the funds could clear and she could pay the contractors in a timely manner.  I also ran into issues with Paypal where they viewed random transactions as security threats and prevented me from sending any money for a 24-48 hour period.  

Does anyone know of a different way I can fund future rehabs?  Or am I just approaching this all wrong?  Thanks!
