Wholesale house prices

[Robin Wilk]

I'm not sure if this has been posted before but l see a lot of wholesalers going after homes priced at $100,000 and below. My question is why, what's the reasoning behind it? Isn't it possible to find wholesale deals above that price point and help the seller out using other methods like lease options etc. 

I basically want to go out and help sellers solve their problems using different contract types that basically are a win/win scenario for all parties involved. 

Having said that I should also mention that my current finances are quite limited to at this point free methods to start. I also have a limited amount of education as well with regard to the type of contract to use. 

So can I go about doing this for free basically? Are my expectations too high to start? What if any advice can you all give me?
