I would have to look back to The Sims 2. :D
I've tinkered with TS4 vampires, but have not played a vampire household extensively.
In TS2 I had a vampire that would seek out the most attractive and interesting sims in the neighborhood and make them her familiars.
She did not work. They did all the gardening, upgrading appliances, taking care of the property, etc, while she slept during the day. I had two at first. One slept at night, and the other slept during the day, so she could be awake with my vampire. They took care of her business and made money to get a larger house. She mostly partied and fed on the party goers, or her familiars. Oh, she also owned a Jazz club in TS2. It helped bring in money.
She would eventually turn the familiars that had been with her the longest.
They would eventually get their own house and grow the coven.
I will eventually do this in The Sims 4 when my master save file is complete.
I can see my vampire acquiring sims with various useful talents and admirable personalities and looks.
I don't think he or she will be a day-walker since they will be very dependent on their familiars.
I guess it's a vampire's version of rags to riches.
Hmm, I will probably need a spellcaster that can put any rabid werewolves on ice.
