I am also curious about this technique as well. I have read different things about turning leases and rental arrangements between parties into a credit building technique.
When I was younger I worked for a large corporation where the owner had a list of over 22 corporations. I can remember being taught how to fill these forms out between companies etc... At the time I didn't know what he was doing exactly - I just knew they were loans between the corps.
From what I understand and remember it can be done between both private individuals and corporations and actually the preferred way to loan a company money or visa versa.
Being that the UCC is filed at the state or county level (public record), it will be reported on a company's credit report (there is actually a space for UCC filings). I believe that even if the "lender" party doesn't report to the bureaus on a regular basis, when the loan has been paid off and a UCC3 is filed the bureaus will pick up the PIF debt and will show favorably on a company's credit report.
I am curious about the 'unrelated party' thing. I remember my old boss made sure each corporation had different officers - mostly employees and always one family members - but he or his wife were always majority share holders. My question is - Are the officers who execute the documents listed at the credit bureaus?
I would also like to know is how a UCC1 shows and effects a personal credit report? I have worked with people rebuilding their credit for many years and I don't believe I have ever seen one on a personal credit report. Because it is a public record will it show like a judgment and look like a negative item, or is there a special place for it like on a business report?
I am currently researching the use of the UCC for building both business and personal credit. And would be happy to share info and compare notes.
