I can see your point brother, but I don't paint a broad stroke over all agents and say they are all dummies, because each of them knows something I don't.

Broadly - Do you want to be an investor, or do you want to sell houses and such?

No specific answer to such a broad question.

I have also experienced Realtors that have provided a cheap, broad, general home inspection reports for potential properties to buy, and I've seen basic rehab budgets provided by realtors for me to look at.

There is no wrong answers here.Buying in rougher neighborhoods can be very lucrative.Landlords are there for a reason.However, you must count the costs of doing business in these areas and determine if this is the right venue for you.If you do decide to go this route, consider section 8 housing.The beautiful thing about this type of rental is that the money comes in like clockwork and will be on the higher spectrum of the rent scale.Further, you should still do your own screening but you have the benefit of knowing that the municipality screened them as well regarding criminal and such as well.If the tenant breaks the rules of your lease, they stand not only to be kicked out of your place, but may also get kicked out of the program as well. 

I'm seeking guidance on key aspects to be aware of in such ventures, knowing well that this advice will offer a broad overview rather than intricate details.

I realize you are looking very broadly because you are new and have not focused in one some niche yet. 

On the other spectrum you may get an Architect that is expecting to develop fully detailed drawings, with many design revision meetings held with you to find the "perfect" plan and 3D design, along with selecting all materials, finishes, and even provide some construction management services.

Now, if you are using the term broadly, that you bought a house, did repairs with the intention of renting it, but saw that prices were high and decided to sell after 1 year, maybe not, you might be able to use 1031 etc.I would talk to an accountant, will be very worth it for a couple hundred bucks

Pretty broad question.
