Ultimately, I am looking to purchase/refinance with or without my siblin co-borrowing, then put an ADU on the home to rent out. 

I also put in two properties that I own, one has 18 years left on a 20yr fixed and the other has been paid off in cash.

You put in the terms of the lease, the tenant name and email and MySmartMove sends out the background check request and the tenant fills in all their information and pays for the check which is now $44/applicant.

Is there a way to structure the partnership that would put both of our names on deed without creating an LLC?

Failure is not an option in anything that I put my time and money into. 

I toed the line every week, each time putting the membership in cart.

For example, she put down a name and number from her contacts that was not her landlord's.

Can anyone advise on if this is true, and, if so why and what alternatives can be put in place to still allow us to do the work personally?

I've listened to enough podcasts to KNOW that I have to build the team first before EVEN putting a contract on a property.

Believe it or not;  95% of owners who are asked if they would like to sell and put some cash in their pocket who have been given a NOD and auction date say no right up to the auction.
