@Malick NgomGet an attorney to send a certified letter requiring signature and include the satisfactionIn most states a lender can be held liable for damages for not recording the satisfaction

@Namit RaisuranaDepends on your preferences and situation of course, but seems as though you've set up a fairly complex structure with somewhat pricey ongoing maintenance costs. 

No financing was required since we were assigning this to a buyer.

The agent will prepare a commitment with requirements for closing including a deed from the party the insurer believes is authorized to sign the deed and any supporting docs they need to be comfortable in issuing a title policy to you w/o an exception for your concerns.

We're actively trying to structure our "buying requirement" checklist to walk through with our tenants/buyers and want to be crisp on our asks outside of asking price. 6% in appreciation in 10 months, not likely :) 

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

(both initially and after investing, such as if you are required to handle any sort of administrative or physical maintenance).2.

We can talk about things like the rebalance test time or the required equity contribution, for example.

A cash out refinance is based on LTV, has seasoning requirements, and would be subject to higher rates. 

@Sung H Kim Depending on your location netting will likely be required at least on both sides of the range to help prevent balls from straying.
