If it's mostly fully occupied you can get a full-doc commercial loan as long as it debt covers.

Industrial, commercial with special use or mixed use2.  

Chris  I would try some local commercial lenders.

Yes this is a Refi on a commercial property with additional large cash out included for sole purpose of reinvesting into another property, as well as a large operating line of credit in addition to the Refi is included.

When you’re ready to retire and want cash flow downsize and move funds to a go NNN net commercial property. 

Prior to syndicating deals, I worked for a commercial real estate investor in NYC for 14 years and gained a lot of knowledge and practical experience while in that role.

Unless you are dealing with commercial, TREC 1-4 works perfectly well. 

Navigating NYC's zoning regulations can be complex @Jon Pflueger, especially in M1-2 districts, which are primarily designated for light manufacturing and commercial uses.
