New Form D on file · 2026-09-15 · the record
What the record says
Everything on the record so far — 2026-09-03 to 2026-09-17. This window lengthens as filings accumulate; it is not yet a year. 64 filings in Commercial, totalled by day. The dot is this raise, $10.71M, on the same scale — one filing against the whole group's total, so it sits low by construction.
Use of proceeds, as written on the filing
An Asset Management Fee equal to 2.00% of gross revenues generated by the Project, payable monthly to the Manager for so long as the Company retains beneficial interests in the Properties.
