Definately check out any and all the forums, books, podcasts and tools here on Bigger Pockets.

Rewey I actually remember when I initially began looking into note investing some years back (probably about 10, roughly) - you and another gentleman I believe had a training course out, or book(s) or something.

Therefore I suggest bookmarking a fe links to access resources like checking out these calculators , the file place, REI resources, and looking into getting some or all of the really awesome and necessary books offered here on Bigger Pockets.

Having said that, your gut feeling may have picked up something subconsciously and a lot of the time that little voice is right (see Malcolm Gladwell's Book - Blink). 

Hello Bigger Pockets Fools,@Brandon Turner, first of all, thank you so much for your podcasts, webinars and books.

That's the first principal element of a quality cost segregation study. https://www.irs.gov/businesses/cost-segregation-audit-technique-guide-chapter-4-principal-elements-of-a-quality-cost-segregation-study-and-reportA "mini" cost seg is basically a residual estimation, which is cautioned against by the IRS because it is generally inaccurate.

I bought Brandon turners book rental property investing and probably sat on it for a year without reading it.

I would plug your scenario in to Scottsman Guide's website and call a few of those groups.

This is broad advice though...my suggestion again is to speak with your agent about the specifics of the deal so they can guide you. 

A good Realtor should know the market well enough to help guide you towards the potentially profitable areas.
