Quote from @Sofia Komrskova: Don't spend that kind of money on courses.

Spending the owner's money, not saying anything, and letting them discover it while reviewing the monthly statement is unprofessional.

The entire focus is on new people because they spend on more.4.

I understand that starting out, depending on how fast you want to build your portfolio, you could spend a lot of time at it.For those with established investment portfolios, how much time is required to maintain it?

If you spend time learning how to manage well, your income will increase, you'll save time, and you'll maintain your sanity with the courage to expand.

I wouldn't spend another moment of my personal time on it. 

Insurance doesn't cover anything anymore and we can almost just pay for all damages with the money we spend on it! 

And how much did you spend in the rehab?

I spend roughly $120k on my renovations, but this is for the entire property and developing the secondary suite which certainly costs more (2 new furnaces, all new plumbing, new kitchens and bathrooms with tiled floors and showers).All said and done, I personally love it.

Spend your time and money learning how to avoid that kind of situation rather than learning from on the job training.
