@Kyle Barton, it depends on your PPM/LP agreement. 

I would recommend talking with a lawyer and an accountant - preferably both at the same time whether on a call or in-person so you can learn about potential tax benefits/drawbacks and if an LLC is right for what you're doing.Also, spend the extra $200-300 and have the lawyer draft you an Operating Agreement - especially if it's not just a single-member LLC and you have partners. 

Mortgage brokers get compensated one of two ways:Lender Paid- Mortgage Broker is paid by lender in a prearranged agreement.

Janet, you can have your attorney draft an assignment agreement or get one from a local wholesaler (one can be found at pretty much any local RE meet up).

Purchase or a power purchase agreement.

Also, documenting everything (Operating Agreement, etc. that I created on a forms website) and having official terms set kept any confusion about anyones role or finances. 

If Auntie can qualify for the whole amount, they could make an agreement between the two of them for his  part of the mortgage payment. 

The question I have is can you still be sued by investors if all correct paperwork and subscription agreements and liability waivers are agreed upon and filled out, investors are completely informed and aware of the investment they are getting into and the risks involved and all securities matters are correctly implemented?

I also use Cozy for reasons mentioned above, plus I like that there is one place to keep the lease agreement, receipts and records for repairs, payment history etc.  

Check your HOA agreement as well since this is outside damage.
