printed houses are bleeding edge technology. 

Challenges, making the deal work by cutting costs and increasing rents will take more time than anticipated Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

One group not to mess with is the IRS and I hear they pay snitches a cut of what they collect in unclaimed wages, maybe the owner can go that route.
