	We investigate the metallic van der Waals itinerant ferromagnet Fe5-xGeTe2 5 - x GeTe 2 with atomic scale, spatially resolved low-temperature scanning tunneling microscopy (STM), and spectroscopy (STS). STM images unveil / / a new structural order 2a a x 1a a along with the known order 3a a x 3a a manifesting as nonuniform domains. STS shows spatial and energy resolved local density of states that reveal the crucial influence of Fe(1) site occupancy on the system{\textquoteright}s electronic interactions. Our magnetization measurements show magnetic anomalies at lower temperatures and identify a Curie temperature (Tc) c ) surpassing room temperature. Collectively, our results elucidate the intricate nature of Fe5-xGeTe2 5 - x GeTe 2 and underscore its potential for tunability of spintronics and high-temperature magnetic applications.</p>
