That sounds like a solid plan!

My current tenant has removed a picture from the wall and replaced the provided bedding with their own belongings. 

Quote from @Kevin Robert Highgate: The ability to invest in property and replace your W2 income quickly is tough.

It sounds like you've got some motivated and cooperative sellers. 

If separate, do they both need to be replaced?

It sounds like you will not have lived in the property for 2 out of the 5 years immediately prior to selling it. 

It sounds like you could just do a partnership with two other people.

It sounds like you’ve got an exciting plan mapped out, and I love that you’re thinking of starting a property management business while building your own portfolio—that’s a smart move.

For this example it looks like I would need to buy it for much less than asking price if the numbers stand right, can an experienced rental/flip investor look and see if these are sound?

It sounds like you've been through a challenging process, but it's great that you're continuing to build your portfolio!
