Finally Purchased our First Rental Property!

Well, after all the readings/learning and webinars I am so excited to say that my hubby and I finally pulled the trigger and got our first rental property under contract, and will be closing in 2 weeks!! We will be implementing the BRRRR strategy and got financing with Private money. My hubby is a little anxious about getting refinancing as early a possible, so I'm thinking to get a head start on researching before the time comes...which is not more than 6 months. We will become new landlords very soon and it seems scary the more I think about it, but I have so much resources and help from my Bigger Pockets family that I'm beginning to feel more confident!! Any advice on refinancing or what we should/shouldn't do at this juncture would be appreciated. Thanks!
