I have been loitering around the city recently and managed to find certain spots that can be used as brand new properties since they look really nice.
- Mirror Park, Nikola Place
I find this street somewhat similar to Grove St, everything looks so modernized and fancy, it has plenty of space and can be used for basically anything fun, such a nice place really. If you could make at least one of these houses a buyable property, it would be pog.

- West Vinewood Mansion
A super-duper big good looking mansion located in Vinewood with a functionable garage, such a great place for big parties or any car meets, you should really give it a try.

- Richman, North Rockford Drive
This one looks really cool but tbh any house from that neighborhood looks just amazing.
