I am fairly new to starting my strategy of BRRRR and I have an important question. Can you use BRRRR on a property that you own out right. If so then call me a beginner but how can you refinance a property if there is no existing loan on property. Can you use BRRRR on a property that you own out right?

Yes you can! Since there is no loan, you would be taking an equity loan against the house - basically borrowing against your equity. You can get an equity credit line or an equity loan. You can borrow up to 80% of your home value but double check that.
