If we can't procure a buyer for the larger packages we will begin listing them after 30-45 days. 

My short term goals are to make bids in the areas that I have conducted rent surveys in near downtown Denver, with the objective of procuring 3 properties by the end of the year (my second property purchase is planned to be a Duplex and I plan to live in half of it).

I was happy to give up 50% ownership knowing that my guys that were procuring rehabbing and handling the day to day of tenants were my partners.

Bottom line, which I think we're all in violent agreement about :) ... materials procurement is a complicated game of strategy and the "right" answer varies from job to job, material to material, business to business, and town to town.

In respect to your financing, that really depends on the properties you find and the deals you are able to procure.  

Approaching the seller during the listing period would be unethical, appoaching them after it expires means they are no longer represented and as Seth points out that becomes an issue for the seller if they attempt to sell without paying a commission during the "protected period".Commissions are due an agent as the"procuring cause" of a sale during a period agreed after the listing expires.

However if you bought a property that was brought to you from a Realtor, he could make a claim that they were the Procuring Party and make a case for a commision.

Any idea how I can use my license with potential investors to procure future properties?

@Brian Adams Thanks for the info procuring larger apartment complexes.How much harder is it to build a new complex in a market where the demand for apartments is very high and the rents keep going up very fast.In my suburb, there are three 100+ unit complexes being built, that I know of.  2 of the complexes were recently approved due to the vacant property not being developed for a while and the land being rezoned to comply.  

If  so you can include in purchase price or terms to make the deal sweeter & procure that buyer.
