Pacaso allows you to purchase more than 1/8 of a residence, you can purchase as many 1/8 shares as you like. So in theory you could easily purchase 1/4 of a residence.
Pacaso is also purchasing homes that are not yet built, for instance they’ve purchased two homes in North Lake Tahoe that are actively being developed.
I am a 1/8 shareholder of a property in North Lake Tahoe through Pacaso and I love the model. Best of luck to you.
