I can't seem to buy Rebecca's Cafe. It's not on the Check Real Estate List. I've read some where awhile ago that some lots aren't purchasable, but I'm not finding anything that verifies that either way. **
** (Maybe) useful list about venues -
https://www.carls-sims-4-guide.com/forum/index.php?topic=2064.0The link above gives some information on what venues can be purchased and shares a note of Player recreations of the venues can be played. However, the default ones cannot be purchased.
I wanted to test this out for myself.
I had an idea of changing the lot type, go back to Sim have them check the list again to see if it's available. It may not be. (And Rebecca's wasn't.) I changed it back to Visitor's Allowed. Checked the list again to see if it was available for purchase and am still not seeing on the list as purchasable. Clicked on the lot to see if it gives me an option to purchase and that's a no.
Some lots are purchasable by clicking on the front door, but others aren't.
Checking in a different town - Hidden Springs. Going to try to buy Hans Tavern and Cafe. I click on it, and it gives me an option to purchase the property right there!!
That tells me that Rebecca's Cafe may be one of the lots/venues that aren't purchasable no matter if you change it's lot type or not. I have not tried recreating it.
