This location is missing a fully furnished kitchen. Sell some expensive art like the coats of arms to finance a kitchen. Buy the most expensive refrigerator, stove, and counters you can afford. Splurge on a food processor too.

There are not enough beds to go around here for all three Sims. Sell some more art to buy one or two more expensive beds and place them in the back storage room after you sell all the junk in it.

Don't waste your time getting rid of the ghosts. It requires the house value to be improved by $1000 first to unlock the séance table and getting rid of all the ghosts with the séance table only unlocks a sculpture.

Always make friends with both Mortimer and Bella. Not only will you unlock to secret social interactions, but you will make 2 friends that will come in handy later and this will accomplish one of the goals of this location: make friend with Bella or Mortimer.

The main skills a Mad Scientist Sim will need here are logic and mechanical. Since this career already unlocked Shiny Things labs for visiting, just visit that location in a good mood and use the Tesla Coil to build the mechanical skill very quickly. Logic skill can be gained by using the Incubator object which is in the back hot house room of Goth Manor. This builds logic faster than the chess set.

Secret: Using the incubator to build logic skill also produces mutant trash-eating plants. These plants can be sold for a profit, or used as trash cans! In additional they eat the annoying flies which are always bussing around spoiled food. Feed these trash-eating plants enough garbage and keep them watered and they will further mutate into MAN-EATING plants. Man eating plants will eat Sims if you don't water them enough!

The main skills a Movie Star Sim will need here are Charisma and body. Since this career already unlocked Tinsel Bluffs for visiting, just visit that location in a good mood and use the Microphone to build the charisma skill very quickly. You can either buy a weight machine or treadmill from the catalog to build body skill, or just visit Dudley's Trailer and use his weight bench for free

By the end of their career, a Mad Scientist Sim will need 5 points in creativity.

Use the Synthesizer to rapidly build the creative skill while living here. It is the second fastest creativity skill building object in the game after the DJ Booth. This will also come in handy if you switch to the Gangster or Fashion Victim careers later, both of which needs lots of creativity.

To unlock a new car, visit Dudley's Trailer and steal the fern out back by the broken down car.

Before you move out, buy a hot tub and a bug zapper or espresso machine before you leave. This will allow you to come back and use the bug zapper or espresso machine raise your energy. Then you can jump in the hot tub to raise most of your other motives to keep you in a good mood so you can keep using the synthesizer and incubator to build skills or stay friendly with the Goths.

Always send the other Sim you can control (either Mortimer or Bella) to work. Their paycheck goes right into your bank account.
