Quote from @Christopher Davis: It's important to understand the court will not award you compensation for your personal time.

Talk to the person who sold you the deal initially to see if they have a recommendation for a lender (local bank, credit union, DSCR guy, or Hard Money).

If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.

Lenders will need to make sure the property can debt service at 1.25 or higher using all property expenses, property income, and depending on the bank, your personal income and personal debt. 

As for the persons you said you would send an application, you may have to just be honest and let them know that since they have pets, you are not going to send an application because you have decided not to permit pets.

Partnership B will be 10% Person A, 10% Person B, 80% Partnership A.

However, as you stated, Memphis can vary significantly by street, so I recommend visiting the area personally and observe the specific streets and surroundings, or doing a zoom call with a trusted realtor who has physically been there.
