leases, in my opinion, are a massive pain. Only leasing i do is on properties i own.

Income producing properties always have a demand and frankly, can be much easier to sell in a timely manner given the current market than raw land is or can be. I would really pick an area that you know well that you think is very strong commercially and at a scale that you think you will be comfortable working on. Once you pick that area...go to the zoning office and learn everything about the zoning that is there or could potentially be there. Understand the direction the planning staff and overall community wants to see the area trend towards. Start calling on other listings in the area and ask questions...how much is the property, how much land, how many sq. ft. in the building, what is the zoning, are utilities all there, etc. etc. Ask to get a summary of the income statement, etc. Pricing income producing properties really is just a numbers game based on income, etc.
Pick that area of focus and then learn EVERYTHING about that area and start networking with people who own those buildings and people who may be interested in buying them.
