Realized a problem just as I was about to purchase a domain

(I'm not a domain investor. I purchase domains to build sites.)

I was just about to finalize the purchase a domain for high $x,xxx when a few last minute checks on Google made me realize there is another domain with the exact same two words but with the word THE at the front.

Example:

Purchasing ExampleDomain.com when a site under the name TheExampleDomain.com already exists and has been trading for years.

TheExampleDomain.com registered April 2003
ExampleDomain.com registered July 2003 (the one I intend to purchase and develop)

ExampleDomain has been parked for years.
TheExampleDomain has a userbase and is a fully trading site (with credit card processing, affiliate system, incorporation, etc).

A US or UK trademark does not exist for either ExampleDomain or TheExampleDomain

My intent is to develop the ExampleDomain.com and trade in exactly the same industry.

Q: Should I skip this domain to avoid the risk of losing the domain via legal means? Or should I go ahead purchase and develop the domain?

PS. The domain I intend to purchase isn't ExampleDomain.com, just using that as an example

 

If there is no trademark and the domain you are purchasing is generic, there is no problem with it.

 

And that's a very big if, considering this:

Don't forget that a trademark doesn't require registration to exist, albeit that's
for the party to demonstrate should it possibly reach dispute.
