I'd love to hear from a turnkey operator here about the benefits.

For this similar price. 2 bedrooms under $300k : rent a room, Reno the condo, increase value and let it ride while paying down the loan , taking tax benefits and growing equity.

If the amount paid to purchase an existing note is below the principal balance or more correctly, the unpaid balance, the investor will benefit from an early payoff to the tune of the discount.  

I'm not 100% sure about each one's different benefits and cons, but which method would you recommend to use if you were in my position?

ever make that kind of claim with any substantial amount of money and for any substantial amount of time.To think, I was actually starting to give you the benefit of the doubt...

Of course as well to benefit from the tax benefits of the sale as this would be my primary residence.

The dollar-peso exchange rate benefited us with respect to fees, so we have some extra class A shares we can use as collateral. 

How can I benefit myself AND my community by offering rentals?

These have ACH collection systems build in along with numerous other benefits to make your life easier. 

The amount of cash-flowing deals in your market is extremely low, so when you get one you should hold on to it as long as you can so you can reap the benefits of that LA appreciation especially if the property is in a good location.
