NE IL - how long to hold asset before refinancing

I purchased a home for BRRR, took a loan out on it. It's cash flowing $400/mo, and we just received our first month rent. We want to move it to my wife's LLC, and out of our personal assets, this was purchased for her growing REI business. How long do we have to hold it before we can take out a loan based on the cash flow of the home and move it to her LLC?
