-Recommendations for Denver real estate lawyers? 

I agree with @Joe Villeneuve.Real estate investing requires a certain set of service providers (RE agent, PM, lawyer, accountant, bookkeeper, contractor, sub contractors, handyman, etc).

The tenant threatens to get lawyers, my concern is their safety, but I can’t get any justification to make improvements to the property for security.

The legitimacy of the contract probably only really matters if you have to go to court/arbitration to enforce it.That said, your title company would be a good place to start in terms of getting a legal review, I'm sure they have a real estate lawyer(s) on staff or retainer depending on the state.

Purchase price: $194,025The Sellers foreclosed mid-transaction and even had to lawyer up to get their lender to look at the Short Sale package.

Lawyer. 

There isn't any benefit to us to go through the extra work of background check, get lawyer to approve language etc. 

To ensure I navigate these legal aspects correctly and make informed decisions, I’m looking for recommendations for a knowledgeable real estate lawyer or legal entity in the area.

I will consult with a lawyer before I do take action.1. 

The neighbor (also a lawyer if that makes a difference) likes to let them run loose in his (and my) front yard.
