Just sent them a rent increase notice every year.

I started down this journey once I realized that being a youth pastor alone would never provide the financial future that I want for my wife and kids so I started investigating real estate and reading "BRRRR".  

We have previously tracked all expenses manually in google sheets and produced financials statements manually, also in google sheets.  

A high property tax rate will increase the taxes more quickly as a percentage of total expenses when the property value increases.

Meet with financial advisers/wealth managers and see what other options other than real estate there are and how to best allocate / diversify. ie have you maxed out your TFSA?

By effectively utilizing space, we can often increase the number of units or functional areas within a property without expanding its footprint.

That does not require employment or job seasoning instead it uses the rents to qualify and you can take out up to 80% LTV cash.Use the cash to put down on the next 1-2 or more properties as long as the other properties are debt servicing themselves it opens up more opportuities to buy more future assets and increase your passice income.  

I think you're missing another point-- if rates increase.

Other most common factor: Family Size increases due to marriage or having a child. 

They will do magic for your financial situation.
