Analysis Paralysis-Flipper looking for long term holds

[Jeff Wallenius]

First post so here goes!  I've spent a good amount of time reading through posts here on BP and I'm truly amazed at the levels of wisdom and knowledge that everyone is willing to share. 

I have been flipping homes on and off since 2005 in the Portland, OR and surrounding markets.  I really picked up the pace this past year and now I'd like to pursue long term hold strategies.  I can find deals that cash flow in Portland, typically the homes that I rehab, but I'd like to continue to rehab homes to create the income to purchase hold properties.  I've researched turn-key properties out of state, I've pondered Multi-family in Oregon, and I've considered Commercial properties as well. 

I know this is a stupid question, however I think I've analyzed myself to death and can't decide where to pursue properties that can return me a 12-15% return.  What insight can more knowledgeable investors provide?  How can I make my dollar stretch further to maximize my leverage?

Thanks in advance!
