Hey @Nicholas Devlin, I agree with @Andrew Garcia approach, but would consider the blanket loan option if you're looking to keep these properties long term. A couple of things to consider though about the commercial blanket..
1. On a blanket loan, the investor (lender) will appraise all the properties individually to get your total value, your LTV will depend on what those value's all come in at and if your portfolio cash flows (or debt services) positively. You may be required to show income and expense documentation for those rentals as well.
2. With blanket loans, all properties must stay under the umbrella of the loan for the entire time you have the loan. In other words, if you had 10 properties under the blanket, you could not sell one or refi one individually, you must refi the entire portfolio to remove that one from the blanket. If you are not sure if you want to keep all properties for that term, it may be worth keeping your individual loans on each of the properties so you're free to do with each property what you'd like.
Hope this helps!
