2) having the knowledge you have now.. what is the best advice you have ever received and why?

For the first 4 months of ownership we only received the tenant portion of rents which amounted to a little less than half of the full monthly rents.

Also, be organized and ready to provide budgets, draw schedule, LLC documents, and Builder's risk and Liability Insurance.

@Alex Tobias  For my last closed commercial loan, I paid:- $350 documentation fee (at closing)- $15 credit report fee- $25 flood determination fee- $150 recording fees to the town- $40 wire transfer fee.- $1,000 attorneys fees for closing.- no points / origination fees.  5.25%, 20 year amortization.- Existing relationship with the lender, who's a smaller local bank.

I would recommend having the process from screening to move in laid out in a “Application Procedures” document to give them in the future.

With the right documentation/agreement I assume I would be able to lock it down even though when it comes time to execute on the option that strike price agreed upon upfront will be 50 or 60% of the actual re-positioned value.  

I think in any case, it is proper to require official documentation to make sure they're registered to do so:http://www.massachusettsmarijuanacompliance.com/ma...I'd never heard of manufacturing dabs/wax. 

If there was a document stipulating this it would hedge your risk but I don't think you will find it. 

But what if a bank could give me a secured loan up to the amount of my documented contributions, while also holding that same money as collateral?

If you choose a plan document that allows for it, like the one we offer, you can make Roth Contributions as well as "pre-tax".
