A stranger occupied my property which is in market for rent without consent in Detroit Michigan.How do I move this stranger out immediately? 

Quote from @Martin Streich: @Sami Gren  it is illegal to edit a contract midterm, even with the tenants consent.

I believe your loan could get called if you transfer ownership to an LLC without consent of the lender, especially a brand new LLC that does not have two years of tax returns.

I would discuss with them, they should have not did these repairs without consent and approval.

This reminds me of a police officer  pulling somebody over without reasonable cause and asking to search their vehicle and if the person does not consent, they’re saying you must have something to hide.

Oh bud, I think it would do that we’re gonna need lender’s consent as well and that’s what I’m trying to prevent, but maybe they do it under them handle that part and then after the fact transfer it. 

Pretty much the same except you don't own it and would need consent to make changes.Also the owner gets all the tax benefits as they are the owner. 

Find a great real estate attorney to help you with:1) Putting a lien on the property, with your aunt's consent, to cover any work you do.- Ask the attorney if your aunt & dad need to authorize lien, or just aunt.2) Understanding your options to force payoff of the lien.- Ask attorney how you can enforce collecting on the lien when you need to.3) Getting full control of the property, while allowing your aunt to keep her ownership.- Have attorney draw up a contract to do this.Suggest you offer your dad some cash, now or in the near future, to motivate him to transfer his ownership to you.It may not work out, but you will learn a lot either way!

Social Security also has a consent based ssn verification process where a SSN can be verified with the parties consent.Again, we can never be 100% full proof but we can stay on top of the latest ways to mitigate the fraudsters at their game.How are you catching fakes?

What worked for me was partnering with a trusted local business or coworking space in the area and using their address (with their consent, of course).
