I am considering the option to obtain my Colorado real estate license to be used as a transaction coordinator. 

The neighborhood is primarily single family homes, so duplex transactions were not as plentiful, but they existed.  

All any agent has to do it set your criteria up in the MLS system and you'll be emailed properties daily.

These platforms previously had a threshold of $20,000 or 200 transactions for reporting.

@Matthew Truncale have a realtor set you up with an MLS search for the type of property you're interested in and then start running numbers daily even if you're not at the point of buying yet.

Appraisals will typically look at transaction with a 1/2 mile radius and within last 6 months.  

As the other commentators have mentioned, you and your lender are going to need ample time to simultaneously review each transaction carefully.

Just make sure your personal endeavours are not interfering with your daily work.

Rent was being paid and I still had to painstakingly keep track of the transactions, which sometimes made no sense or didn't add up.  

The key for most land transactions is can it be developable and appealing in terms of locations.
