As i understand it, the government will soon let you roll over your stock proceeds tax free into purchase in areas deemed “opportunity zones”.

All of a sudden though, they are asking for information about the property such as property taxes, rent roll, insurance from the current owner, etc. 

I later "refinanced" it so to speak by rolling the balance onto my HELOC at 5% to increase cash flow.While technically not creative financing, I got a $21k mortgage from a local credit union earlier this year for another property.

In practice its a total roll of the dice.. with the local that own and run these having loaded dice.. and those trying to do it out of state crapping out !!

If you've got good credit (680+ FICO), a seasoned rental property (24 month rent rolls), and equity, the terms from a traditional commercial lender would be ideal. 

Make sure you've got good records: 24 month of rent rolls, maintenance schedules etc. 

He was dubious, but was too polite to actually roll his eyes at me.  

As long as they were receiving enough leads, I would roll the dice as well. 

I generally don't even do that as my lease rolls over to MTM and I typically leave them MTM until the tenant moves.
