You can build credit with the LLC to make future purchases.
In the meantime you can use cash or hard money as you mentioned. Or you can take out loans in your personal name and credit and then transfer them into the LLC. You will need to make sure this does not conflict with any of your line guidelines etc.
If you would like to discuss further or come up with a solid investment strategy for you and your partners please feel free to contact me directly.
