I don't think he would allow someone that had to put the fee on a credit card.

So is this just as simple as showing how much the property makes or do they also look at personal debt to income, credit score, reserves etc as well.

A couple issues with Credit/income on paper.

Sales agent gets slightly more aggressive than I like, but other than that, they seem more trustworthy than other opportunities like this that I come across.

My business partner owns a roofing company but has weak credit and more limited cash flow.An LLC is a common choice for partnerships since it protects personal assets and simplifies tax management.

I made that mistake with a 2 bedroom condo - after 1 year, I had to shut down operations due to HOA rule violations of NO short-term rentals less than 30 days.#8 The 30 day+ rule -  Certain places Airbnb is outlawed or a softer rule is the 30day+ rule.
