@Ross McKenzieAssuming you didn't just choose a realtor that has no ethics or morals at all and that you are looking at MLS type properties it is unlikely your broker violated his obligations just for you. 

In addition, if they are members of the National Association of Realtors® there are a code of ethics that could be involved as well. 

And the property is now pending contract.Now strictly for educational purposes, did she violate any code of ethics?

I like your energy and work ethic.  

I know ethically it's not ok to approach homes that are already listed by an Agent, i understand that and respect it.  

Are there any legal or ethical issues to be mindful as an investor that does have access to the MLS?

And as a realtor no one questions your ethics :)Alternatively go get your home inspectors license.  

To be honest, I think it was his confidence and work ethic alone that made him successful.I grew up in suburban CT and found that people were generally friendly, I would imagine that if you are friendly as well, it shouldn't be an issue.

If so, could I ethically characterize $17.5K of my loan as being used for the purchase of Rental-A or is it too late?

These are professionals with additional training and a stricter code of ethics.
