Private loan from family

[Colin Potter]

My partner and I are preparing to make a cash offer on a home funded by our own cash partnered with a private loan from family. We've drafted our promissory note, have the funds ready to move, but I'm not finding any information on the web regarding the proper place to have the funds when the purchase is made. Should our private loan come straight from the family savings account it's in to pay towards the house? Or, should my partner's cash, my own, and the private loan all be transferred into a separate account before making the payment on the house? Are there any tax traps or other challenges we could be setting ourselves up for by doing this one way or the other? Any relevant information is appreciated!

We currently do not have an LLC if that affects any answers. Both my partner and my own name will be on the title.
