Hi, nice to see you also made the switch here from lemmynsfw ^^
I personally think that in any such dynamic it should be established that your job, family, friends, finances and health shouldn't be negatively affected by the dynamic.
A master/owner/etc also has a responsibility to look out for you and how you are doing.
Financial independence is definitely a good thing.
Hard limits should be communicated beforehand.
Even if everything works well, any kind of dynamic and relationship benefits from regular communication, everybody should have a personal conversation about how things are going with there partner every 1-2 Months. Even if there's nothing to improve currently, highlight what's been going well and what the other person does that you love. Makes it just better for everybody.
Don't commit to a stranger, it sucks to commit and then find out you are incompatible. If there's a previously established dynamic, build from that gradually to see how it develops and if it works for both people.
And of course always be safe an look out for yourself <3
