How to not "Commingle" funds

[Sharon Steenbergen]

Hi, I'm trying my BEST here to do my own accounting for the most part.

Currently I have an S -corp established for my fix and flips and an LLC for my long term holds.

Most of my business funds are in my S - Corp bank account. 

STORY:

Just purchased a new rental (in my personal name) its pending a quick claim deed to the LLC. Anyway long story short - the rehab cost for the home were charged on my personal card. How do I properly pay off my personal card with the Funds in my S - Corp account without raising red flags. Or can OI not use those funds because I haven't put it in the business name?
