Call a bunch of title companies and ask them, they would know.
You might or probably will get a lot of title agents have no clue what your talking about so they'll be like, "whats your number and I'll get back to you"
if those words are mentioned, either hang up and call another title company or ask them if they can do WRAPS.
Wraps are very similar to Sub2s and there is a chance that a title company will understand that.
If they tell you NO you cannot do those transaction here in NM, ask them for the proof that you can't or refer you to their legal department to have them explain why it is not legal whether they call it a Wrap or Sub2
You could also contact the Attorney Generals office, but your not going to get any straight answers there unless you can find an article or press release relating to Subject to's or 'creative acquisitions in real estate' detailing certain laws that they will most certainly cite in those press releases/articles.
What ever you do, do not go to the department of Real Estate or any other agency that is obviously funded and structured for Realtors b/c they will tell you anything outside a standard typical transaction involving an Agent is illegal.
Hope that helps
