From a distance these read like the same decision: two newer downtown high-rises with skyline views, a Walk Score of 99, and the same walk to Amazon. They are not the same decision. First Light is newer, taller, and larger, finished in 2024 with 459 units across 48 stories in Belltown. Nexus is the 2020 building, 389 units across 41 stories, sitting inland in Denny Triangle. The age gap, the size gap, and the neighborhood gap are the things that actually matter here.
First Light gives you the most recent construction in the comparison, a taller tower, and a Belltown address closer to Pike Place and the waterfront, at the highest published entry point, from $800K. Nexus gives you a lower published entry, from $650K, a few more years of resale track record in the building, and a position in the heart of the Denny Triangle and South Lake Union core. Neither wins on the amenity list alone. The better-positioned unit in either tower beats the weaker unit in the other, every time.
Before you choose, I put the two specific units side by side on view orientation, floor height, monthly cost per square foot, parking, and the current HOA reserve and assessment position. With a four-year age difference between the buildings, the reserve study and any planned capital work read differently in each, and that comparison, not the marketing, is what tells you which building is actually the better buy for you.
