I am wondering if anyone has ever taken legal action against property managers, and if they think we have a potential case? 

multifamily and single family both have potential value.

If I pay it off, I could maximize cash flow earlier, reducing financial stress and allowing me to focus on other ventures or simply enjoy life more.On the other hand, I know some people advocate for keeping cheap debt and using the extra cash to invest elsewhere for potentially higher returns.Why I’m leaning toward paying it off:Security: No debt = peace of mind.Financial freedom earlier: A fully paid-off rental would give me a significant monthly cash flow?

EDUCATE YOURSELF - yes, it will take time, but will lead to a selection that better meets your expectations & avoids potentially costly surprises!

Lots of older houses but there seem to be several that have the potential for cash flow and while not exactly modern on the outside, have been renovated inside. 

That's 50k a year gone and you are losing tax write-offs and equity potential.

Additionally, the price point is still cheap enough to find the 1% rule and positive cash flow and there's amazing appreciation potential.

Once I've completed these initial projects and built up some capital, my long-term goal is to transition into buy-and-hold investments in potentially more affordable markets to maximize cash flow and scale up.Right now, I'm particularly interested in investing locally here in the Seattle metro area.

But if you get a major expense you could then potentially have a decent amount of debt.
