A spreadsheet or microsoft word is about the same with the exception of formulas.  

It is literally edit them in Microsoft Word, submit them with payment to the county clerk, and the eviction happens in a few weeks barring the tenant fighting it - which they seldom do if they know they aren't paying (they know they are in the wrong).  

I have to agree, every loan I have is tracked in Microsoft Excel.

But if you are an organized person doing small volume as a start-up, Microsoft office is excellent for what you need.

Just saying...One of my favorite technologies is stuff like google drive and microsoft SQL Azure databases.

As for software the simple answer is Microsoft word.

I worked for Microsoft for 10 years (while Gates was there) and know a lot about the work that he does -- he does very little "advisory" work outside of his own foundations, and he does very little in the area of real estate outside of his own firm -- Cascade Investment -- which is run by his money manager, Michael Larson.Just like the guy I was going back and forth with above -- don't believe everything the so-called "experts" tell you...That said, to answer your question, I certainly don't have the knowledge of Bill Gates. 

I don't think the lack of a stamp will make a difference because I'm sending out postcards until I learn Microsoft Mail Merge (at which time I will change to letters with real stamps).

The mail merge option will insert each name and address for you instead of you doing it one-by-one.In Microsoft Word, you can be walked through step by step by navigating to the Mailing tab, then click where it says "Start Mail Merge," and select the last option that says "Step by Step Mail Merge Wizard." 

I am proficient with Microsoft Office Suite.
