I just think agents need to educate themselves better on market analysis and the rest of us as consumers need to know how to vet an agent.

There is 2 types of wholesalers in my opinion.  

I know that just offering on MLS houses might not get me the numbers I want, so I'll have to use other ideas to find properties (like driving for dollars or calling landlords on Craigslist to see if they want to sell).As for what happens if no one buys/rents, while I realize my opinion isn't prevalent on here, I don't buy anything I can't afford to pay for if no one wants to live there. 

I'm NOT an expert on this, so take my opinion for what it's worth, not much. 

I've seen many different opinions on this topic and have struggled to come to a conclusion; is it best to start with a large property (15+ units) or begin with a small du/tri/fourplex?

Set aside some time each day to educate yourself. 

Scott's book and some other online resources would be brought up so let me mention that I've already read all of those during the past 6 months of my education phase. 

I guess in my opinion purchasing condos is probably your lowest return on investment and the highest risk.

I have spent the past 6 months or so educating myself on REI as much as possible primarily here on BP by listening to countless podcasts, posting tons on the forums, analyzing hypothetical deals, networking with other investors, realtors, wholesalers, lenders, contractors, etc.

Upperclassmen are ideal, whereas, sophomores coming from required dorm living take more education on this whole home responsibility thing.Sorry, if I may have gone a little off track. :-)
