Let's try and bringing it to an apple-to-apple comparison.

If I were you I'd also do the math on buying a primary residence and a couple of SFR rentals just for comparison because those could certainly be on 30 year loans.

My point is that just comparing a CAP rate to a treasury yield is not a complete comparison.

@Thierry Lemercier I am not familiar with Avail's functionality, so I can not do a comparison. 

So when you see one of us say “consult your tax pro” or “you should get a CPA involved”, we are not soliciting for service, we are both protecting ourselves and trying to protect you as well.Hope this shines a light on part of the discussions.I'm not sure this is an apples to apples comparison.

I made a page for each rental I was using as a comparison.

Seller's end up being responsible for your malfeasance so while it may be "off the books", the liability remains to some extent no matter how your purchase and sale agreement is structured with them.You came out guns blazing against my statement, without clarifying your position, until I poked holes in your comparison between your position and that of the OP.

But at least here is a cash vs. cash comparison. 

The cash flow there is excellent, but I would go into it assuming things will not appreciate as much over time, especially in comparison to Northampton and Lehigh Counties.

In this sense, they are accomplishing a goal of making a relatively affordable (in comparison) unit available to the owner-occupant only.
