Some want to call themselves a hard money lender and then enjoy the protection of conventional lending criteria for their underwriting, @Justin Lallatin.

Any other contracts that purport to protect your interest might do that , but only after going through the legal process.

General Partnerships do not off you much liability protection and as a result you see less and less of them around. 

Are there services available that specialize in rehab protection or security?  

I have the cash to bring the loan current, however, how do I protect myself from paying the loan current and losing the deal?

It is also important for us to have personal liability protection to protect our personal assets. 

Then truly care for them...look out for them...protect them...and do it all for nothing and expecting nothing in return.That's the important part. 

In NH there was a recent bill to add two new protected classes:1. 

However, I would take some asset protection steps to protect myself on the front end. 

You also need to be ready to close if you can not wholesale the deal or have contingencies that protect your deposit.On market deals are harder to find in an up market but some investors are successful with agents doing this especially with properties that have had extended days on market without activity.
