I have been to guru courses and paid seminars and expensive year-long trainings.  

Assume your first few deals will be for training rather than to make a killing.

There is a large capital investment in training people for this work as it isn't something people can go to school for or that there are clear training programs for.

Pick a random S corp client of yours, be a robot, fill this out, you might be surprised:https://new-content.mortgageinsurance.genworth.com/documents/calculators/Training%20Form%2091%20(2017-2018)_12413401.pdfWe see people show up in a corvette, business bank accounts show $50k/mo coming in with only $5k/mo going out in expenses, then you fill out the form based on tax returns, and Fannie/Freddie think the dude is broke as a joke.

You have to train your tenants.A very successful investor who owns a lot of stuff around me, has a maintenance phone number.

This gives you the opportunity to ignore all b.s. requests easily, and train your tenants to not get answered when they make such requests (they will catch on quick). 

And here in NC there are wildlife protection laws that made it illegal for them to be removed by someone not trained and licensed.

Mortgage Brokers are independent, trained professionals licensed to represent and provide you with the best advice for your mortgage needs!

For a new investor it’s honestly great training because most other places landlord tenant laws will be a breeze if you adhering to MA’s. 

My suggestion - better in time and effort, and money (through the mistakes you going to make), than paying a guru.Between BP and books and all the other podcasts and blogs available for free, you shouldn't need any paid training - don't fall for that.
