Finally, BP has various tools available to help you analyze your deals (rental, flips, wholesale, etc), feel free to use them: https://www.biggerpockets.com/investment-calculators Please let me know if I can help, and best of luck!

Additionally, HELOCs are a great tool.

Also, with the tools and materials that are needed in the repairs, it seems logical that there is some business expense write off and tax breaks I would be able to workout if these expenses were inside of a business and not out of my personal pocket. 

I think firearms are better seen as tools for self defense than investments, unless one is an experienced collector or trader that can run a business.

Anyone aware of another tool that does the same? 

I have not used the tool before, but to my understanding the potential tenant will order their own background and credit check, which will be sent to you.

If you want to be a productive realtor I would go with a larger brokerage that has the tools and training to help.

They give you some great tools, and they also have some great training/info on this very subject. 

Can anyone tell me if there is a tool on the website to find accurate rent numbers 

The agent that told you that is correct, however commission is negotiable, you can offer them a lower rate to list a property or use it as a negotiating tool in their next purchase assuming your broker approves, also it incentivizes them to use you again for their next purchase.
