It is defined in terms of actions which would not be acceptable to any fair and honest man, or conduct which is monstrously harsh and shocking to the conscience.

Most places define short term as less than 30 days.

those are pretty broad questions. 

To me, signing a broad exclusivity agreement kills your bubble; you're now cut off from every other agent's network.Of course, it has to be worth the agent's while to bring you a deal over someone else, so try and offer something of value like a finder's fee or, if you're flipping, the right to list the renovated house with the agent. 

It is pushed over and over and over, especially on social channels and from service providers, and often interchanged with other terms and defined differently constantly, but mentioned again and again. 

So if you define a motivated seller to be someone that is willing to sell their house below market value (which is the ONLY definition of a motivated seller), you will then realize it is very different from:"A motivated seller is someone dealing with a foreclosure, tax lien, inherited a property". right?

Additionally, I've been spending a lot of time evaluating condo / HOA management solutions and accidentally stumbled on ManageCasa, which offers a free trial and < 3 unit free tier that has allowed me the time to get in, kick the tires, and really appreciate their attention to detail and broad feature set that adapts to each unique industry sector.

Your question is pretty broad.

How does one define design choices, etc?

However, like any market, success depends on selecting the right neighborhoods and building a solid team on the ground.In Indianapolis, areas like Broad Ripple, Fountain Square, and Irvington have seen strong appreciation and rental demand, but they can be more competitive.
