@Michael Quarles I can honestly say that I've never gotten any solid business from postcards.

I also own a water restoration and general maintenance business in the area and the amount of STR owners that we have spoken with is insane.  

I would focus on being an agent and building that business.

So it sounds correct to collect all amounts into my business account then and send a 1099 to the owner reflecting what they received minus the PM fee?

Of these professional wholesalers, nearly all of them will be well capitalized professional real estate investors or large businesses doing hundreds of deals annually with many years in and around every part of the real estate investment journey.

A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant specializing in real estate taxation, business taxation, financial planning and tax planning.Consider working with your accountant remotely to expand your options.I would also recommend looking for an accountant willing to work with you throughout the year.

How do you approach educating people on the realities of the business? 

Redlining IMO would only be an issue if @Jimmy O'Connor said to stay away or refuse to do business somewhere; he did not do that, he just pointed out property characteristics.

And I'm not saying this to earn your business just as if it was a residential property.

Our business model is built around working with investors to find them great returns and I would enjoy a conversation around what you are trying to do.
