With this amount of windows, savings could be meaningful.

Other than the "pre-qualification process" please feel free to share any other meaningful differences between these two types of transactions.Thanks SO much in advance!

You're leaving out vacancy, rent loss, concessions, maintenance, utilities, capital expenses, accounting costs, legal costs, etc.In total, expect your NOI to be about 50% of your gross market rents...in other words, cut your yield in half...Also note that when it comes to rental real estate, it's more common to refer to "cash-on-cash return" as opposed to yield, as it's more meaningful given that leverage is often involved...

I am not claiming there are not many that have better BRRRR processes than I have, but I would hope/think that it is few that have better processes that have not done at least a half dozen BRRRR.My point is you may be able to extract all your investment via BRRRR (I have even if it required an assist from appreciation), but doing a large number of BRRRR in a year will not be easy and likely require significant experience. 

Nothing you indicated is incorrect, but 1) If the F/F rule is enforced it will affect his ability to extract equity via a refinance. 

@Ryan Bakerian: having done a few commercial loans in the past (small balance loans, likely similar to his), I didn't find the "red tape" any more meaningful than personal loans on my primary.  

At 7%, the first 5-10 years earns the buyer relatively little principle, so I'd be receiving a ton of interest up front and still have meaningful value waiting at the balloon payment.Question 3: Any reason why this would not be pretty interesting for a 1031 exchange investor?

We long ago extracted all of our purchase costs.If I limited myself to 1% properties then I would not have purchased the property. 

With tools like Podio, data extraction is a nightmare. 

I have thought about that but I am not sure I will be able to get enough out to have a meaningful enough deposit for the next purchase.
