You need a proof of funds or a pre-approval to go with any offer so if it's hard money, they will issue a letter.

You always want some proof of who cashed the check and where it went. 

When you go blasting people for ponzi etc without proof I would never do that, but if you lost money in a deal a way to shape it was?

We make them sign and acknowledge all the fees at lease signing Then when the tenant gives notice we send them the video link and the pictures to let them know that is how we expect to get our property back.Then after the tenant moves out we take another video and another 150-200 pictures for before and after pictures and proof should we ever go to court

Time is critical, especially in competitive markets.Clear Offer Terms - Present a firm offer with terms that make the seller feel confident that you can close fast, with minimal contingencies or proof of funds.Due Diligence Preparation - Have your financing lined up and know your repair/rehab costs in advance so you can move quickly without second-guessing.

Inability to show proof.

no banks, no credit , no W-2, no proof of income needed. 

There are a lot of groups out there right now that had made-for-TV track records that will likely not be in business in a couple years.Focus on the experience of the team, how long they have been in the business, how many market cycles they’ve survived, their philosophy on leverage, and how many properties they bought in 2022/2023 (a good answer would be few, a great answer would be none).And do yourself a favor and read The Hands-Off Investor (in the BP bookstore) before you invest a single dollar in a syndication.

Proof this method does work.  

And I generally require a sponsor that has full real estate cycle experience with little to no money lost, low leverage, high skin in the game and reasonable fees and promotes.However, other investors will look at these deals as bad/too boring for them because they are more aggressive and not concerned about the risks of default, refinance, interest rates changing etc.
