We currently have 3 rental houses and this was our first full flip so i'm just hesitating on which tactic would be better for us.

This is both an offensive and a defensive tactic.

Is this a new guru tactic being taught?

Ratings are interesting to look at but some use "bait tactics".

My main objective for now is to learn more about developing/building a site for my LLC and also wholesaling tactics that others have used with good experiences.

What sorts of tactics do you use to find motivated sellers of MHs?

It seems as though this is an often used cheap tactic some landlords use instead of filing for eviction.

This isn't to say a DIY tactic isn't doable, it absolutely is, you just have to work a bit harder.

Yes, it's a stretch from your case, however if you and your family can show evidence of a portion of a population that is employing this tactic, it could set precedent in identifying scammers in the system.

What advice/tactics/strategies do you have for learning to determine rehab costs.
