I want to start analyzing multi-family deals, what tools should I go for?

@Anthony Liguori  The places you mentioned are merely marketplaces (with some tools to help due diligence) where buyers and sellers of properties can connect. 

From our perspective as investors and agents, a license is a great tool, not just for access to the MLS but for earning some money to invest in deals once you find them.

, seems like a story in the interest of one particular political party's most current attempts to get voters to vote for them. 

@Jacob Sampson I've been using the bp rental calculator tool and aiming to buy in such a way as to get 250/mo at least.

However, I recently became a pro member specifically for the use of the tools and calculators.

Not sure what you're asking as the title and question are different.Funding of an off market deal isn't different than on market you have the same tools available.Finding an off market property can be done through the purchase of various lists and marketing to that list in your chosen manner, direct mail, cold calling etc. 

It has very helpful tools, resources, and networking capabilities.

What tools do you use to find seller emails and send email blasts?

What you should spend your time looking at are market fundamentals such as supply and demand, the strength and diversity of your local economy, and the laws and political trends that are impacting being a land lord.
