I would give the lender a 1% origination fee and payback the interest on the loan in 2K/monthly payment.

Hey Cam, welcome to BP - I'm from Boston originally, happy to connect with you!

Thank you for the indepth feedback to the original poster.

In Colorado specifically, we’re also losing a lot of options due to an increase in our wildfire risk scores in many zones.  

A U.S. credit score wouldn't be required but more money as a down payment would be.

Quote from @Brandon Croucier: Well once the loan is Originated there’s no taking one out and adding another, I wouldn’t touch a blanket in that position then, there will be difficulty taking one out/penalties, definitely just suggest a cashout refi.

Given your experience and strong financials, you have some solid options:Commercial or Portfolio Loan: These are tailored for investors and can help you avoid personal guarantees, especially since you have an LLC.BRRRR Loan (Buy, Rehab, Rent, Refinance, Repeat): Some lenders offer BRRRR-specific loans with funding for purchase and rehab, allowing you to refinance based on the new ARV once stabilized.HELOC or Cash-Out Refi on Current Rentals: Tap into the equity on your single-family rentals to secure funding for the 4-plex purchase and rehab without high origination fees.Each has pros depending on your cash flow goals and timeline.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

In my experience, the cash flow may be substantially reduced (or even become negative taking into account interest rate of original loan and refi closing costs).

But I did the install myself, not everyone wants to or can, do this.But in answer to your original question.....it is a solid NO.
