FNL is the Northern Colorado Regional airport, in Loveland. It used to accomodate light commercial travel, but was shuttered through Covid. Last year, it received Federal infrastructure grants to widen the runways (accomodating 737 bodies), opened two new gates in a freshly-renovated terminal, and has a project underway for an advanced, semi-automated control tower.
There's a ton of tilt-wall commercial construction going on around the airport in Loveland, along with a massive, new, and mothballed Amazon Warehouse. If it attracts commercial and business commuter travel, I can see the area blowing up if/when economic conditions ripen. For now, the same job pays 20% more in the Denver Metro area, despite home prices fetching similar money.
You'll want to be in Fort Collins or Loveland for tax diversity. Windsor and Timnath are going to be built out 90+% residential with most new neighborhoods adding a metro (MUD) taxing district, tied to a 20-year bond package. Fort Collins proper is already 70% developed, and with I-25 opening the inner tolling lanes, I can see future development fill out the Front Range from Berthoud to Wellington.
