Then you follow with a letter saying you are the new owner/manager and the next payment is due by X date at Y address or Z method.

Just wanted to know what would be the basic steps in order to get that started

Once you solve the problem of sourcing Off-Market deals, the next step is finding cash buyers.

I have a construction back ground so right now I am using the Brrrr method and plan on moving from single family to multi-family. 

I’m in a year lease (until oct 2019) and want to finally act on the house hacking duplex method.

I would tell them the problem didn't exist before they occupied and that you've taken steps to keep it from happening again.

I figured it would be a long road to remodel, but it’s just not talked about, unlike the HML then BRRRR method.

A split to 80/20 could be problematic because it doesn't reflect the Joint nature of the tax return and could be seen as a step transaction if she was to only do an exchange on her 80%.Owning as Joint tenants is certainly a possibility and in fact the one that matches the tax return. 

@Daniel Sutton describes another method I have seen used to tie up a person's property, however that method also comes with risks, as you are essentially putting a cloud on the Seller's title.

My strategy is to utilize the BRRRR method.
