Downzoning (commercial to residential) in Colorado Springs?

[Robert Wright]

Bigger pockets team,

Taking a twist here from my typical SFH & duplex buy & hold rental strategy. I recently found a commercial property that I want to convert to a residential rental--it is an old downtown Victorian originally built as residential and converted many years ago. Before I get started, am looking for advice on any pitfalls to consider before I engage in a zoning discussion with Regional Building. The numbers are pretty good in terms of acquisition cost, rehab and rental income...I assume working with RB is an expensive and exhaustive necessary evil? Property next door is a Victorian residential rental as well...
