With that said, is it worthwhile to send direct mail to a property that's still showing delinquent taxes more than 2 years old? 

I don't see moving them as a worthwhile endeavor.

But there are defiantly some very seasoned Wholesalers out there that know the do's and don'ts (laws) and have very successful wholesaling businesses, and can really take property that has just been sitting around doing nothing but being an eyesore and repurpose it and turn it into something worthwhile.

Make an offer on the property to see if it's financially worthwhile, if the seller accepts this, then go check it out to see if it's actually worth the effort.

If I am charged one penny more than i am supposed to be in a transaction and i am not properly notified and have time to figure it out if the property is still in my affordability range and worthwhile to me.....

If that wont at least cover what your expected payment and any problems that may occur will be then it wouldn't be worth while.

Aloha Daryl - investing in real estate is definitely a worthwhile venture, especially in Hawaii where the price points can make one deal the equivalent of multiple deals on some mainland markets.I want to give you some friendly and constructive advice.

Hopefully, you're a motivated enough of an individual to make those activities worth while, effective and efficient.

Ultimately, spending a few million in Cuba to scoop up prime real estate which could net exponential returns is worthwhile.
