If so, do you think it is worth purchasing or are there other competitors that get the job done? 

My competitors send mailers, letters, DMM, bandit signs PPC TV ads, and WE GET THEIR LEADS!

Being able to close a loan very quickly is a great competitive advantage that will separate you from a lot of competitors.

EVERYONE is doing it wrong.Do it yourself.That is the only way you are sure you do it correct.It is easier than you think I promise you that.Then lastly... sure the advantage of DMM is you are getting your own leads... but when you stop marketing the leads stop.Not sustainable.An other disadvantage is that when I do my walk trhoughs and walk the houses of some of our leads (that I got for free as they look for ME, not me looking for them) I see STACKS of yellow letters and postcards from competitors.... you are one of SO many sending mailers... yet they pick me when I didn't send them a SINGLE mailer.We even sit there with iced tea in my hand as they offer us cookies laugh at these poor suckers sending mailers.

What makes you different from your competitors?

The bad thing about wholesaling is that is also true for all of your competitors, and due to courses just like the one you took there are thousands of new people getting into wholesaling each month. 

@Laxmi Chirravuri Best locations typically have 6-7 square feet of storage per capita within 3 miles or less and also have low availability of land so your competitors cannot build more.

Unlike many of our competitors, to avoid churning our units and then filling them back up with new people in the same financial position, we have found it to be good business to work with tenants having a temporary financial crisis.

To give you a rough idea, this AirBnB near Asheville, NC will be our closest direct competitor.

@Paul Kuhn - yes, they are GOOD competition:) So many of our competitors are incompetent or crooks, but still suck in owners that don't know any better with their cheap prices:(
