its never done till the mortgage records.   

Remember that if you do not have ownership on the title the owner of record can come back and make things difficult for you.

I get an idea of what is on record thru county recorder website and 3rd party vendors like Black Knight or Datatree. 

You never know what you’re going to need in the future and it’s so much better to have records than to not have them.

Are you recording a physical assignment?

Sounds like it was recorded After the LOC mtg was recorded....otherwise you wouldn’t be looking for a subordination agreement for the LOC?

But there might also be a good reason for it that they can explain.Some other things that might apply to your deal as you head towards closing:- Typically there's some kind of review of the preliminary title report (to show any encroachments, liens on the property that will be paid off by escrow at closing, any covenants/codes/restrictions that are recorded on the property, etc.)

And let her know that since you have not received the property back from her, you will evict her and her rifraf once the courts are open for eviction and it will go on all their records, and you will haunt her for the rest of her life keeping the unpaid rent as a collection on her credit report until she pays it. 

Is there any sort of closing - we must need to record something somewhere? 

Thern, once you start getting a track record, you can push for a higher percentage and you will have real world experience to back you up.
