These crime stats are usually compiled by the FBI via local law enforcement agencies.

You've really got two good choices.Go to a law text supplier and find a compilation of statute and case law.  

In Michigan, look at Section 339.2503 Exemptions; definition of Michigan Compiled Laws which contains the definition of real estate brokerage:Sec. 2503.(1) This article shall not apply to an individual, partnership, association, or corporation, who as owner, sells or offers for sale a detached, single family dwelling, duplex, triplex, or quadruplex, which has never been occupied and which was built by the individual, partnership, association, or corporation while licensed under article 24.

@Drew Sygit provides some excellent advice and you've compiled a great list.

I am compiling an offer for the house, and the agent is asking me to sign a document that has language that I am not fully understanding.In my understanding, the agent's commission is paid by the seller, but in "Client's Obligations" it seems I am responsible for 3% of the purchase price of the property or 50% of the aggregate rental of the lease and all options as exercised. 

Start compiling a Buyers List and ask them about the areas they are interested in buying from.

Whether you are an active investor researching markets and cycles, or a passive investor doing your own due diligence, you want to compile some resources.

There is quite the variety of options available for screening packages; tenant involvement/no tenant involvement, instant reports, hand-compiled reports, and even income verification.You can find further information by going to Tenant Screening under the Tools tab.
