I am in an industry where we work of "worst case scenarios all the time" so my mindset is always to think that way. 

The worst part is this was a fairly large facility.

Continue retirement contributions, work 40 hours, make minimum student loan debt payments, save up personal reserves, save enough for down payment on duplex, buy duplex.Five and six are the worst options. 

We granted a best case scenario, so we should grant a worst case scenario. 

I figured that in the worst case I would sell it later at a small loss - after all, it's a nice house, and people always need a place to live.At the time I wasn't intending to buy more properties.

@Isaac Johnson2-4 is probably the worst investment in my area.

Obviously buy and hold you are looking at cashflow and appreciation and not in a hurry to do a flip.What are your best and worst case exit strategies?

Worst case scenario they say no and you move on to the next one.

Collateralize-debt and if you are selective about only lending on properties you wouldn't mind taking over then even a worst case scenario you could leverage to your advantage.   

@Jamil Mitchell usually for sale by owners are the worst leads.
