No matter if you try to help, if they can exploit you they often will.Like others have mentioned you need a license and even when you don't if something goes wrong, you could face lawsuits if you even smell like giving them official advice.My REAL advice however is this, and I hope you take this warning seriously.Let's talk about foreclosures for a second.According to data a few years ago (it is worse now) every 3000 mailers will get you 1 deal, which makes the chances of them wanting to sell their house 0.03%.This means 99.97% of the time, when you approach someone in foreclosure they are not interested in selling.So understand what you are factually doing...You are going through all this trouble to EXPLICITLY try to find people that do NOT want to sell their house (people in foreclosure), to try to get them to sell their house?

Some bipartisan congressional legislation, like the HOUSES Act, supports this effort by making portions of federal land available for residential development.While this approach has promise, experts warn that opening federal lands is only part of the solution.

Just be warned that it may not work the way you envision it.

By my standard I suppose we can put a bold lettered warning at the top.

Many other have warned about HOA's...stay away from any neighborhood that doesn't have an HOA and isn't zoned specifically to be STR.

Did they give any warning and did people go on to create other Alumni pages of their own?

I would think a detection device would be easy to fool or disable, and difficult to prove in court.I would focus on inspections and look for the following evidence, then document with pictures, written warnings, demands of cleaning/repairs, and follow-up inspections.

Additionally, these investors can provide warnings about potential red flags, ensuring you hire reliable contractors and property managers.

YOU HAVE BEEN WARNED! 

Your warnings and advice will be shared with my partners.
