I did my due diligence, but when a company markets itself as a turnkey property expert, they should ensure the property is solid and their affiliates are reliable.

they probably have a bunch of 3% nonconforming loans on their balance sheet so 5.5% is not bad, totally reliable payments, plus in a legal battle they'd likely find the power of attorney didn't extend to the ridiculous term and that there was no breach of any enforceable agreement.   

Make sure you’re connected with reliable contractors and property managers who can act as your boots on the ground to keep everything running smoothly.

While Redfin isn’t the most reliable source for estimating the values it indicates that I have about 400k in equity.

With consistent rental income and a strong potential for future appreciation, this property offers a reliable addition to any portfolio.

So it's not very reliable.

This will give you basic, reliable cash flow, without tearing your hair out.

Is it high interest rates, finding reliable lenders, or something else entirely?

You'd be better off building a solid emergency fund and developing relationships with reliable local GCs.

To scale, I plan to build a reliable local team, leverage 25% down payments, and use strategies like HELOCs or cash-out refinancing for future acquisitions.Good luck!
