@Hugh Wagner,
Whether or not to lend from an LLC is more a matter of choice than liability (I'm not an attorney). Lenders don't really have much in the way of liability in the property. The only place it really exists is between you and your borrower. And, a good mortgage & note will strip the borrower of most of the frivolous stuff that can happen in a loan away from them. Your paperwork should absolutely be tipped in your favor. You're the one taking the biggest risk.
How much is your borrower putting into the deal? If yes, have them put those funds up as part of the purchase. Control the rehab funds through an escrow account. Most title companies can do this for you.
Are your rate & terms adequate for the risk your taking? How well do you know the area you're lending into?
If something goes wrong during the project, do you have the ability to jump in and take over if necessary? Can you call the loan due at any time? What are your points of control?
Does the attorney you're using to set up your paperwork have experience with lending? What kind? How much have they done? Hard money & private lending is a very niche industry. There are not that many attorneys out there that truly understand it. You may want to go take a course on it.
Anyway. those are just a few more thoughts I had about it.
Good luck!
