If you are trying to use primary residence loans on properties that you do not plan to live in... that would be mortgage fraud. 

Infos on the Mortgage company:Phoenix Mortgage Group LLChttp://www.phoenixmtg.com/Their commercial lending company ishttp://www.wepinc.biz/I've heard of mortgage fraud and i have a few doubts about this company.

I have talked with my lawyer about this matter and they said nothing we can do at this moment unless I am willing to pay a lot to file a "insurance fraud" claim against them.

If you are concerned about the 'fraud' aspect of your brother, I would reach out to the voter registration board in your county and/or DMV with a phone call and ask them if this is something you need to report and go with whatever they say. 

My application is almost identical to the one found in Mike Butler's book "Landlording on Autopilot". 

Had you said aluminum wiring of identical diameter as copper could not handle the same power as the copper, then that certainly is a fact; but without qualifying it to the same diameter wire, then that is not quite right because one would just get thicker aluminum (back when it was in use) to handle the same load  The interfacing with copper is quite significant when you look at the DIY types who aren't aware of this.

Putting properties under contract with no intention or ability to close that's called fraud.

As far as your other questions, just replace "real estate agent" with "your lawyer" and the rest of the process is identical to a typical transaction.

Tenants that can't find a landlord willing to rent to them, that are then removed by bailiffs, will choose to squat in vacant properties. 9) Application fraud, regarding residence history, will increase and be an ongoing problem.

And that's tax fraud - call it a threat or just sibling encouragement.
