I still  have to do some more research into the individuals behind both concepts but what option do you believe offers more value?

In general, I would say - do not get stuck on the house hacking concept just because it is talked about so much.

Deadlines are almost a foreign concept in Mexico, so we've learned to set them far in advance of our desired schedule.70% funded. 

Got a good grasp of the concept, with very little info on the step-by-step actions I can take.  

I don't understand how so many people can live without any concept of a conscious!

For simplicity, I've assumed no principal paydown on the original $300,000 mortgage.After two years: $400,000 × (1 + 8%)^2 × 75% - $300,000 ≈ $49,920After three years: $400,000 × (1 + 8%)^3 × 75% - $300,000 ≈ $77,914After four years: $400,000 × (1 + 8%)^4 × 75% - $300,000 ≈ $108,147While the above example is oversimplified, the concept is valid.

Your app concept sounds promising!

@James Kerson check out companies already doing (or those that have tried) something similar/same in concept to what you're describing.
