Using Cash out refi to purchase 2nd rental property help

[Jerry Knight]

Hello, I am currently looking at purchasing my first rental property, being a single family home. I was intending to use a normal conventional loan to put down 25%, however that will absorb a majority of my available capital to use on it. I am wanting to scale several properties a year to build my portfolio, as I am looking at the long term hold aspect. How soon can I realistically complete a cash out refi on my first home to use the equity to use as a down payment on the 2nd home? Is there a specific process to do that? And repeating this process? any information will be super helpful. Thank you!
