You created the mess by making sure you squeezed every last dime out of your departing tenant and now you want every last dime out of your new tenant.

Yet somehow all the economists and major investors have Austin continuing to be one of the top 5 cities to invest in. 

But be careful because this is also an opportunity for them to sell you a major B.S. line or try to manipulate the situation.

The sellers have agreed to pay a majority of the closing costs and to fix some vinyl siding that needed to be repaired.

Depending on the location of the property, $100,000 per unit will provide you with a nicer investment, but will probably not cash flow very well unless you plan to purchase in a major metro.

The majority of the value may involve the desirability of the land, not the structure itself.

Start with the zoning department to make sure they will allow you to expand. 

It is highly unlikely that any other investor will outbid you at a foreclosure auction to acquire the remaining half of the co-owner's half interest in the property -but in the very unlikely event that someone does outbid you, then you'll have recovered the majority of your costs, plus interest and you'll get a new and likely better partner.

However, I think the majority of people on here, if they went to Excel and used a few analysis formulas, will realize quickly the reason that flipping is so prominent currently is due to the lack of scalability in the real estate market at a certain point (beyond $100,000 homes) the effort vs. reward becomes questionable (not a steadfast/absolute rule, but on average it becomes more questionable...sizable risk vs reward).
