But we have heard we may get a better deal, so no harm finding out, right?

You're dealing with people's lives and their most valuable asset, so when you tie it up on a contract with no ability to perform on the contract and without the proper knowledge, you're harming your reputation long before you have one.

It avoids their credit getting harmed more than it already might be.

While your reply gives me "food for thought", your lack of examples leaves your post lacking much true substance.  

Even if you have two activities ( flips and rentals) under one entity, they will still be taxed differently and having them in one entity does no harm to taxes.

As some have asked, "What harm did it do to you?"

The math rarely works and your offer could actually do them more harm than good.

In fact, it's up to all professional type real estate investors to police their industry as well, not just internet sites, so I hope they are doing so on a local level when they see things going on that have the potential to harm the indusrty.

Not to take notice could be harmful to your business.I don't know, give me something more well thought out that shows with reasonable certainty that they can't make a legit fraud claim.

The key factor in the scenarios I described is that the damage or alteration I creeated was easily fixed or done to items that already required replacement so no harm, no foul, don't ask, don't tell.
