If you have a great-paying, long-term tenant, a small discount can actually save you money in the long run.

But as long as its not directly in the flight path, it will be okay. 

Curious how this will play out in the courts (granted it's LTR) and affect pricing products used for STR such as PriceLabs (which I use but have to seriously manually adjust for very specific reasons). I'm aware that ...

Also, I work with a lot of long-term RE investors and none of them look at ROI.

I've had them long enough to keep pushing up rents so that I am at the top of my niche, but know not to exceed it because I'm just about at the point where if I raised rents another $50-$100 I'd be crossing over into the lower end for larger units.

I do have some investment experience and I'm currently managing 1 property, all the numbers are great and there's a good amount of cash flow and long term growth so I'm not a total green horn. 

Focuses on stable, long-term returns.  

But a really good property, for what you can afford, in a good location like Charleston and wait. 

Since they've lived there so long, I recommend giving them 60 days to move as a means of softening the blow.Third, don't negotiate or accept excuses.

This seems unlikely in the long run. you are forgetting that someone is paying down your principal for you so you need to take that into consideration.
