Eventually, once the units have appreciated a bit and the mortgage has been paid down to the point we have 20% equity, we split the parcels into individual town homes and then she refinances her unit out and I refinance the three units out or sell them. 

@Michael L.The said company might have to rent the equipment at first but eventually all successful companies will have their own equipment.

Eventually she moves out and on to the next and we manage the property together.

Even if you do I would sell this unit.The negative $3k will decline with time and eventually go positive.  

You know a stove will go out eventually, you know the estimated price, you know the estimated date, you don't know exactly when. 

Additionally, I am willing to live in one of the units for a year.My long-term vision is to buy everyone out and eventually own the property entirely.What are some common deal structures I can explore based on my contributions and end goal?

I will eventually rent out my current home.

But I also felt strongly that I wanted to live there myself for my bachelor years, that I should take advantage of low interest rates, and that it would eventually at least break even as a rental.. so no regrets.

Eventually, laws were passed that required the Banks to accept Replacement Cost coverage.Suppose you loan $500,000 on a property. 

They may eventually pay you....nothing wrong with getting $15k, right?
