Simple: First off, digital products have virtually zero overhead or shipping costs...
Secondly, I've spent the greater part of my life helping folks start and grow their real estate businesses, and thought..
"How cool would it be to exponentially increase the number of people I can serve by creating an insane level of value at a price just about anyone can afford?!"
And of course, I'm also doing this to generate revenue. Can't be more direct than that. Something I learned a long time ago from my Mentor is that, if you sell someone a product that really stands out and help people get results, those people will come back and buy even more of your stuff!
So anyway - now that we've appealed to your logical and emotional sides, it's time to get the offer :)
