However a zero tax Roth is better than depreciation in my view.

Use the BRRRR plan as you described until you have the rentals that you want

Let me know more about where your properties are located, if you have a vrbo page or website so I  can view your properties, and any additional info you can share.

What I would do is get a licensed GC to view the properties and give you a line item quote to do rehab on all unit, and the outside, and bundle that into your loan/cost, then move fast!

Also, I would create a Offering Package describing what you want to do and potential returns.  

It might be a little harder on the front end to cover the increased payments, but in the end you'd pay significantly less interest than you would following your method.Sorry if I sound like a sour-puss contrarian; I actually really love these kinds of posts that give real actionable advice, but I also like to hear and offer alternate views.

These liens are public records, but how do you view them?

@Mike SedlacekThank you for the view point.

The deal you describe gives me the picture of a desperate handyman.

The terms your described on your in-house conventional loan look interesting and I would like to lean more about it.
