The article describes essentially a revenue per sf of leased space, and then a 7% "rental yeild" I think they call it, that 7% is essentially a cap rate from what I'm understanding, just a different name for whatever reason. 

This buffer might seem excessive, but for me it's essential to be able to sleep at night and ride out the bumps while leveraging myself.3.

Lots to unpack here...In my experience the cash flow is essentially a marketing tactic to push people thinking they will retire within a few short years due to this "mailbox money".

While long-term appreciation and tax advantages can justify holding such a property, weighing these factors carefully and aligning your decision with your specific investment strategy and goals is essential.

Finding partners to fill in the gaps where your weaknesses are is essential.

I’ve seen a number of experienced investors, real estate agents, and even mortgage officers give pretty poor advice on these forums at times.Experience is only one element I consider, as there are others I find far more valuable (intellect, whether or not they’re truly paying attention to your post, etc.).Regardless, whenever I’m told something, I research it myself for either more insight or validity.

Then you would be essentially creating a brand new lease, with your terms (with whomever you choose).Personally, I don't re-screen inherited tenants.

@Kyle TolbertYou essentially did seller financing.As a result - the $5,500 that you get every month will be paid towards basis, capital gains and interest income.In simplistic terms - $5,500 x 12(months in a year) x 30(per the agreement) = $1,980,000.You will be reporting $1,230,000 of interest income over 30 years.More of the interest income will be reported in the earlier years since not much of the payment will go towards the principal.The bad thing is that interest income is normally taxed at ordinary rates.
