Let them know the standard procedure and that you are planning to follow it.

I don't know procedures or remedies in your state.

My presumption from the OP was that having had the REC/Installment contract with a proper Escrow Company as a Trustee that proper procedure to recover the equitable interest was done.  

Every state has different rules / procedures, but in some, once a property is sold at a tax deed sale, that is it.

Does anyone have a package of all the docs they typically use for a lease of property, and a typical run through of the procedures they follow and the steps taken from start to finish of the process.

It can be a slow, tedious process or it may go fairly quickly, depending on the facts and circumstances.The process and procedure may vary state-to-state, however the basics are that you make an offer and if accepted by the seller (guardian of the minor's estate) certain criteria must typically be met regarding price relating to court referee (appraiser) value and down payment.Your offer may not be the final one, as it may be possible for other to show up at the confirmation hearing and bid up the sale, however in many jurisdictions there is a minimum overbid formula that prevents other buyers from offering the "penny over" nonsense.Most of the time these sales are formalized and either listed through independent or contract broker/agents or the county public admin or guardian.If you're new to real estate, you may find the process frustrating however there are deals to be found.

In fact it can help a lot to have a written checklist and procedure you always follow, in case you are ever accused of some kind of discrimination.

It's kind of like taking a friend's dental xrays to a random dentist to have your teeth worked on.

Our procedural manuals moving forward will be based on some very relevant initial experiences!
