It depends on your financial circumstances.

Desperate people, properties and circumstances are their bread and butter.

Not that I was neglecting it before, but the pressure is on because soon I will be "fully adulting."

Granted, those units aren't in the hippest/hottest neighborhoods in the city, but they also aren't in completely neglected areas either.

It’s whatever you agree on, but I’d be ready for things or circumstances to change in the seller’s mind over that long of a period, especially it the property appreciates significantly above your price.

The expected time from closing on the purchase to closing on the sale is six months, perhaps 12 months in extenuating circumstances. 

It depends on her goals and facts and circumstances.

Then, take your original $100k (you never spent it...no matter how hard you tried), and keep it.Never under any circumstances, for any reason, spend your seed money. 

I wonder what the circumstances were that warranted that kind of drop in price to something that isn't even close to market value.

I’m thinking you’d need some other “circumstance” to quickly sell a property “bought for long term investment”, under a 1031.
