It seems like a major missed opportunity.

I ask because we only buy houses around the southern US (TX,OK,AR,TN) but we're curious to know if more opportunities to buy foreclosures could potentially exist in other markets. 

Have you considered selling and capitalizing on another opportunity.

I also purchased the "training/coaching" and received very little support and what I did receive was not very valuable.

Savvy investors can find pockets of opportunity within the market.

Also, make sure to keep your eye out for seller financing opportunities. 

What RECENT "buy" opportunities do you see in the overall market?

@Micah HuffmanFrom what you have said here, it sounds like you have your hands on a very good investment property/opportunity.

Looking in Denver metro for either SFH or STR opportunities.

@Kristin MathernI would pay it given no keys were provided, it wasn’t specifically addressed/mentioned in your lease, you were provided the opportunity to address/fix yourself with a 25-30 dollar replacement from Lowe’s/Home Depot, and lastly, it was an existing situation that could have been avoided/prevented at move in.
