Why do I have a 404 error in the TurnKey theme?

I am working on a Realty website for a client and I cant figure out why there is a 404 not found error when I have everything set up how it should be. So basically there is a property section in the dashboard very similar to the post section and you set up your categories and then publish properties into the categories no differently from the posts except that you fill out specific information, but when I go and click on the property thumbnail(that is created by default when you publish a property) It just take me to a 404 page. Does anyone know what my problem is?

Here is a link to the website: https://www.michaelsellstexas.com/

just scroll down a little past the search that initially pops up and click on “Example ‘Residential’ Property”

and here is a link to the demo to show you what it should do: https://www.mojomarketplace.com/item/turnkey-a-simple-real-estate-theme-for-wordpress/demo/51bf8c63-fb40-4e4a-b8c2-2cee0a140b2c
