It sounds like you’re on a solid path!

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.

Aiming for each part of the business to eventually fund itself is a solid plan, and a real estate CPA or attorney could help fine-tune everything for taxes and structure.

You’ve already built a solid foundation with podcasts and resources like The House Hacking Strategy.

You’re on the right track, and it’s a solid strategy to start with long-term rentals to build a stable income base.

I would lock in a solid profit.
