- what could be a better alternative? 

Would anyone be able to help me find an alternative way to find the remaining 20%.

I think the most important part is learn a technique from someone and follow their system until you start getting results.

Are there other alternatives for this, aside from the P.O.

I likely cannot qualify for a conventional mortgage at the moment so I'm wondering what the best way to get started possibly using an alternative financing method without making any major mistakes.

In an earlier post I asked what marketing techniques others are doing in highly competitive markets.

We buy houses, manage fix-and-flips, manage make-ready projects for buy & holds, wholesale houses we choose not to renovate, and sell houses to retail buyers.We have some experience with alternative financing options such as sub-2 and short selling.  

Check out Meetup.com for alternatives that really are free and are more closely aligned with the BP culture.

Even then, you might be better off focusing on these same type of techniques where you're investing with other people's money, essentially, which leaves your own money available to work for you in other ways.  

They just started doing meeting in alternate months in Waltham and Worcester (Wor in Aug).
