Lloyd Stanton excellent suggestions!

Either ask or find someone skilled.Communication, always and often.Weekly photographic progress updates.When you run into an issue have multiple solutions along with any cost impacts at time of discussion.

If you refer back to your contracts/agreements with your tenant buyers, do the documents include clauses about -- a time frame for them to give notice of their decision in writing to you whether they exercise the option or not; your ability to transition them to a month-to-month tenant should they fail to exercise the option; your ability to market/list the property and offer it for sale to someone else; your ability to conduct showings, inspections, appraisals, and photograph the property prior to them moving out if they fail to exercise; etc., etc.If so, then your good. 

I haven't done direct mail for a few years, but when I did, I used Excel. 

It'll give you an Excel spreadsheet with all the property info and mail information.

Oh, he did say that I could do a short sale-I said that is not an option bc I have excellent credit and I  am not doing anything to jeopardize my credit. 

I now have to place a sign on my property that says FOR RENT with small FOR SALE letters below it because for sale signs are expressly allowed but for sale signs are prohibited.I have also had the HOA fine me for the tenant letting the grass get too tall which the tenant denied and the HOA refused to email photographic proof of the violation.

A Glock 19 is an excellent tool. 

Hire a professional photographer, not only will they take high quality photos, but they will also give enough photos for you to lay them out in a way that gives a walkthrough of the property.
