LTV & CreditEliminate the emotion and treat this like the business it is.In my opinion it does not matter who the borrower is as long as they have a track record of ATR (Credit)And I feel comfortable with the leverage (LTV)

Property management....it just make business sense as a leverage point for efficiency of your time. 

Start by leveraging what you already have—consider tapping into equity through a HELOC, house hacking again with an FHA loan, or increasing cash flow by converting a unit to a short-term rental.

I don’t know of any camps of people more entrenched than the “cash flow is all that matters” and the “you must use leverage” people. 

If you use it as several down payments and use leverage you could be off to the races with many more Class B or C units that will still cash flow for you.

There’s no shortcut to experience, but you can accelerate your learning by leveraging other people’s experiences.One of the best ways to do that is by attending meetups.

You would be 100% leveraged, and you'd have 2 separate loans (One HELOC and traditional mortgage).

What is the best strategy to leverage this for my goal?  

Leverage your construction expertise to accurately estimate rehab costs and streamline renovations, and focus on financing strategies like hard money or private loans for your BRRRR deals.

@Stephen FlemingFrom my experience working with over 400 investors, your strategy of leveraging a low mortgage rate, tapping into home equity, and diversifying with a short-term rental (STR) in Northern Michigan is well thought out.
