We put a ton of emphasis on our telemarketing and sms lead generation.

You guys are putting out some great info--I was just looking toward a slightly different emphasis. 

The numbers look ok but that can vary GREATLY based on the ares, the age of the building, the age of the major mechanicals, how much work will be needed once a tenant moves out to make it rent read and other misc variables.

I look at the return on the total investment with an emphasis on cash flow-the rest is inedible.

I'm a mechanical engineer currently working full time in the utility industry.The more I read and learn, the more I'm realizing that my next move would be to invest passively to gain experience for future investments.

My post was more along the lines of things that might not be so obvious other than 50% for expenses, and check mechanicals for serviceable age remaining.

Getting the license will first help educate you on real estate, second allow a mechanism for you to make money from real estate. 

I look forward to learning everything I can about real estate investing, with an emphasis on purchasing rental properties.

Some don't care about the borrower's income, but put a lot of emphasis on their credit and experience. 

I've joined the two major landlord Facebook groups for Ontario and it's been an eye-opening reading experience.. the mechanics of screening tenants such as verifying income and credit are still a total unknown to me so I appreciate your advice.
