Personally I would just get the proper licensing and insurance if I wanted to manage properties for others. 

Personally, I wouldn't open up a home that isn't in good repair, from a liability standpoint if nothing else.

You’ve already got mortgage and taxes in mind, but here’s a quick framework I personally use to ensure no costs are missed:1.)

I personally walked and researched every property prior to investing to understand what I was buying, what could be done to add value and what I should expect in cash flow and appreciation.Learning what makes a good investment for you is absolutely necessary. 

That could work if you find the right person.

.: My question is… Do people promote buying rentals due to some sort of  personal benefit/conflict of interest?

How much can you get on a personal loan?

If you put in the effort to source the right opportunity, you’ll find a way to fund it—even with minimal personal cash investment.It sounds like you already have the skills and experience; now it’s just about structuring the right deal.

While under contract, we perform due diligence and there will be some soft costs incurred. 

Nothing personal.
