Experienced acoustic player needing apartment-friendly keyboard...Yamaha CLP-240?

Hello! I've got a question regarding the CLP-240;

A bit of a backstory... I've been playing piano since I was very young. I inherited two acoustic pianos (an upright and a baby grand) but they're way too heavy to move into any apartment so they're at my parents' house until I end up with a home of my own. I hate having to go over there whenever I want to play but I've been hesitant to look at digital pianos because of the lack of emotional connection with the instrument.

I've recently realized that it would actually be nice to have something that's more portable to simply practice the notes; I also like to play by ear and it would be great to be able to play along with music that I'm listening to and have it at a low volume or use headphones. Recording ability would be awesome, too.

The day that I told my parents I was going to start looking for one my cousin sends out an email saying that she has a Clavinova CLP-240 that she's trying to sell. I haven't done a ton of research into digital pianos but this just seems serendipitous, especially since my major priority is for it to sound and feel like an acoustic and it seems like that's what they're known for.

SO, that leads me to a few questions:

1) She bought it for $500 used, didn't play it much, and is asking for that much for it. Is 500 a fair price if all is in working order? I believe it has all the original 'accessories' (bench, cover, dvd, ...)

2) Do they have a 'half-life'/degrade in quality over time? Or a point where it would be more of a value to find something a bit newer or offer her a bit less because it's changed hands a couple of times now?

3) Is there anything that would be a red flag or that would lessen the value once I see it/try it out? I'm having trouble finding that kind of info.

Thanks in advance for your help, I'm hoping to make a decision on this soon. Watching videos and reading all of this makes me really excited to be able to play whenever.
