I am also happy to supply some referrals from some "reputable"agencies in the area.

When it is triple digits, a prudent landlord supplies window units/portables or puts them up in a hotel (or airbnb) for the night. 

I was residential loan officer/mortgage broker from 2000 to 2008 and a Realtor since 1993.  2008 and the next few years were difficult times to be in real estate finance so I jumped to bank owned sales during this time, so I have both perspectives.Both as an LO/mortgage broker and real estate agent I would regularly have banks/lenders ask for a comp-based appraisal and a rental survey on 2-4 units properties; which is Fannie Mae Form 1025/Freddie Mac Form 72. 

Understand what they need and how I can supply those needs.

All they have to do is also get appraiser to supply the rent on the report. 

I'd run this by your broker to make sure you're not breaking any office rules, but I am also licensed in CO and see no issue with it.

His office is off of 25 and Hampden.

Is this something that should be supplied - or should i expect to be told a price, address, and do all of my own due diligence to make sure it checks out?

I just dropped the price on the rent a little below market and I worked with different people until I found a tenant that was fine with getting their mail at a post office for the reduced rent.  

I would like to have read a few from any state before arriving at our attorneys office, so I can bring to question some of my concerns.
