How much leverage do you figure success real estate investors (as defined in my original post) employ -- more than the typical 5:1 or 4:1 that can be found in ordinary mortgages?

So, if you decide to go to college, then maybe get a business degree.In general, college prepares you to be employable not to become an investor.

You are now starting to see evidence that rent is also decoupling from income.Naturally, this cannot continue, eventually employers will be compelled to relocate, or virtualise, to both afford facilities and retain a productive workforce.The difference with LA and Vancouver is that the average house price in LA is in the $500,000 range; so although both the housing price and wage growth rate in LA or the US may not necessarily be materially different than that of Vancouver, just the average price varaiance of a house in both cities will tend to make Vancouver seem more unaffordable.Housing and its affordability is a serious issue.

If you're going to continue investing in low-income units, I would suggest you employ a good property manager.

It's also good that your subject line of your post actually indicates what is going on and what your question is..........Too many posters have been starting an annoying trend of "click bait" where the title of their thread may be something like...You're not going to believe this!!!!!!!!!!

Employment history... is there any where that could finance a mortgage?

Even if you old it for more than a year, but your property  is flip, you are going to pay ordinary taxes plus self employment taxes if you do it regularly.
