Had you objected when you reviewed the title commitment prior to closing, they probably would have paid it, or you could have walked due to not getting clear title.  

If the Plaintiff published the notice as required by law, and the case was allowed to move forward, the foreclosure was completed, the sale took place and no objections were filed, you got your CT...

Bells and whistles will be added if the proof of concept goes well.As far as deploying it for REI (not sure if I understand the question fully) but the objective is to identify on market, public deals far faster than any human could possibly do so.

I would typically pick the approach based upon my objectives - i.e. if the tenants were on a term lease and I wished to retain the original end-date, I would execute a Change of Lease.  

I have no objections to that... but what I see is a big marketing cost factor....  

I have heard the objection to hard surface flooring in the bedrooms, to which I tell the tenant to buy an area rug.2. 

Either you both sign a release OR one side can demand a release from the title company, and if the other side doesn't object within 15 days, the title company is supposed to release the money. 

She is asking me to sign an NOC letter ( No Objection Certificate ) as her Landlord as part of the Visa application process to prove that they have a place to live together, although they will be moving out basically immediately after he arrives.I'm very unfamiliar with the whole Visa application process or how signing this letter could affect me knowing that they don't plan to stay.

Just make sure you trust who you're working with to give you an objective opinion!

Also you say fully furnished and it looks like no one is living there since the closets are empty, but there is clutter and random objects under the TV area, a bowling ball ect.
