@Nick Allen Paula Pant (a former podcast guest) has an excellent article on her blog about the rent/buy calculus. 

Just something to consider in your calculus.

I went to 3 semesters and I have 2-3 close friends that I could see myself doing business with in the future, but I feel that I could meet more like minded people in a local BP meeting than in Calculus or History class..

Buy local, self manage, 1 business checking account, 1 umbrella policy, 1 LLC, 1 spreadsheet, Cozy, tenant selection calculus, M2M leases, trusted contractors.

Then I think only you can make that calculus 

Once I figured out that my basic education in math (adding and subtracting) was more important than my college Calculus, (and accounting), I started smiling again.

Perhaps add that part to calculus.

@Matthew Paul But a "guru" of REI said wipe UP, not down, UP, so we must all do this, he's a "Guru" of REI, he fart's roses and cherry blossoms, defecates gold bars, in 3rd grade instructed his teachers on calculus, knew how to ride a bike before he ever saw one, and not only walks on water but waltz's on it....... 

That's a calculus that depends on supply and demand of your local market on one side and investment return on the other.You also lose tax deductible interest on the paydown, which shouldn't be a primary consideration, but should be considered none-the-less.Again, not a financial advisor, just a tax CPA

I aced college level physics and chemistry and calculus 1 & 2 in High School.
