Your lender is confused because he's one of the overwhelming majority that goes an entire career without learning anything but how to finance single family homes for married couples intending to live there, which is the overwhelming majority of mortgages written.

PS -  it's Sunday so I will be calling all the appropriate departments and the like tomorrow to get some answers. 

Owner states house has no major issues currently (will be getting appraisal and inspection) only,cosmetic repairs may be needed.

I’m not sure Colorado’s laws are the same but you could check with the Colorado Department of Real Estate for their specific guidelines.

Don't know about your city, but I think in many locations you're going to have a hard time explaining to the code people or the health department about why rat control is the tenant's responsibility. 

Caution:Contracting for repair, maintenance, remodeling, or improvement by any person licensed under part I of chapter 475 (real estate agent) while acting as the owner’s agent pursuant to that license, where all work requiring a contractor is performed by a contractor who has a current, valid certificate or registration issued under this part to perform such work, and where the aggregate contract for labor, materials, and all other items is less than $5,000; however, this exemption does not apply: (a) If the maintenance, repair, remodeling, or improvement is a part of a larger or major operation, whether undertaken by the same or a different contractor, or in which a division of the operation is made in contracts of amounts less than $5,000 for the purpose of evading this part or otherwise.For the sake of your cousin's license, either make her a part owner (sharing the gross profit as her compensation) or get a GC on the job asap.Just a helpful hint to keep a fellow real estate agent out of jail. 

A bit ironic as I think most on here would agree that the majority of agents don't understand/participate in real estate investing.

However, most major cities will have one. 

The only "savings" is if you were coming from another private, untraded syndicate with high fees (which isn't that common for the majority of people on BP). 

Are the units in rentable condition  right off the back  or would they require any major attention before being able to rent?
