Investment properties used as rentals are considered by the Federal government to be commercial properties rather than residential. That means that in addition to receiving the 25% dollar-for-dollar tax credit off your Colorado income taxes, you can also receive an additional 20% dollar-for-dollar tax credit off your federal taxes for approved work done on your historic income property. Additionally, the City has no interest loans (up to $7500) and a Design Assistance Program ($2000 of free consultation) that can also be used for maintenance and improvements. And every single one of these financial benefits can be used together on one project, which can take a substantial bite out of the cost of owning a historic rental in Fort Collins.
