According to the agent involved in the deal, they think I can get these numbers...

A smart seller/listing agent will likely require a large EMD to tie you to performing on your offer, so be prepared for that. 

Right now, I am an aspiring real estate agent specializing in investment properties while also in the process of developing an app!

IMHO the key is having an agent on the buy side who understands the process and can make some magic happen for you. 

Networking with local wholesalers and real estate agents who specialize in investment properties can also lead to off-market opportunities.

I would love to hear from those who have actually invested in these areas vs. realtors/real estate agents.  

Even still, it could be said that I've still lost money due to my time on the tools instead of prospecting as a real estate agent (the cost of lost opportunity).If you can truly do 80%-90% of the work yourself (at acceptable quality levels) and you aren't sacrificing your time where you can get better returns for your efforts, then yes, it can work even up here in Canada.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I'm currently building my team with Tax Advisor/CPA, RE Attorney, REI friendly agent and designer first on the list in that order.

Just make sure you use a very honest agent that doesn't sugar coat anything and check the crime statistics and household income.
