Lot's of direct mail, a simple website, some pay per click. 5k is enough to pull in multiple deals, and plenty enough referral money to perpetuate the marketing machine.

That sounds like the kind of thing said when you're having a character respond how you want to stereotypically imagine them.

I'm always confused by how this idea seems to have been perpetuated that there is somehow some kind of loophole where you can give away money, but then by writing things off on your taxes you can end up coming out ahead. 

If receiving perpetual spam texts is your thing.Postcards do not need to be handwritten.  

And made a nice perpetual cash flow in the process..Anyway, welcome again, and good luck!

Is there any cap or could I potentially be charged into perpetuity?

Being swift, effective and fair.I wouldn't label these people as dead beats or create a stereotype of such.

Make sure you estimate the future value of the $20k minus taxes vs. the perpetual cash flow your will receive from the rental property.

I was attempting to contemplate the potential of a business model that could offer a family cash flow in-perpetuity by removing the ability of potential heirs selling the golden goose. 

If you think there will be perpetual 25% vacancy, don't buy the property.
