.- The TL states that those are technically the team's leads and I will owe the 20% if they convert within the year since I was given training (which I was not), lender referal (which was forced on me by the TL even though I work with my own lenders for my clients).Is the above statement true/legal/valid?

Even though I only have 1 STR, I use OwnerRez which allows me to require a signed rental agreement and place a hold on a valid credit card.

The problem (as you have cited) is trying to understand what you need (you don't know what you don't know), where to get it, qualifying its source(s), and the validity and usefulness of all that.Pardon me if I've gone into this too much, but I meet many people with the same concerns that you are voicing and this is offered, as much as possible in direct response to your post.Please feel free to contact me if you have any comments or questions. 

This is a touchy subject.If you observed specific concerning behaviors during interactions, such as rudeness, aggression, or disrespect for property, these could potentially be valid reasons for rejection if documented properly.You should add one very important things to do on your checklist, past landlord references and it must be legit and find out why they aren't there any longer.

Most new construction deals require you to give up to a 10-year warranty on some items while most fix and flips come with very little extended liability after the sale excluding gross negligence which is not stopped by an LLC in any case.

The builder home warranty will help with no out of pocket expenses.

The warranty company is the money making business.

Exactly, that is a very valid point just ask WHY?

I have ESA valid doctors letter proofing that, but need to send the addendum to sign now.

@Andrew Syrios that’s a valid point.
