"1-Day loans for Doubles", Any pitfalls?

does anyone here have any experience with these types of loan providers?
If so any pitfalls or things to look at. One company was actually a MLM!UGH!
Some seem like they are private equity companies or private investors. I live in Phoenix and would like to take down a few deals.

Not any pitfalls that I can see.

You don’t have any costs out of pocket and there’s No qualification requirements.

There’s plenty of good ones.

I am wondering about these transactional funding services , do the realtors/Banks usually accept the Proof of Funds as valid? The funds are only there if you have a buyer willing to pay more. So I wonder if agents would be hesitant to accept the offers…because they wouldn’t want to tie up the property with an investor that hasn’t ‘qualified’? …

Anybody have experience using these services?
