Excellent reference for all levels of HP 12C use 
2007-02-27
This is an outstanding reference guide to the HP 12C. For those who are trying to understand the 12C from the very beginning to the more experienced users who need to "brush up" every now and then, this book has it all. An unexpected bonus was the customer support offered (should I need it). The human element tied in with such an outstanding book (at a more than reasonable cost) is something that I haven't seen for decades. It's really very simple. If you want to be knowledgeable of a financial calculator that virtually hasn't changed in over two decades - and probably won't in your professional lifetime, then this is the book you need.
good HP12C book

The only thing I didnt like about the book is they dont explain everything they present as problems. Otherwise the book is great for learning the HP12C.
Awesome info on the HP12C

Just received my Professional Real Estate Problem Solving Using the HP 12C book by John A.Tirone. I really appreaciated the quality and service I received on this order. The book arrived (as said-for the time arrival expected) and the quality of the book was above what I was expecting, not forgetting to mention the personal backing of the author for future service connected with any questions I may have from using the book, by Mr. Tirone. Mr. Tirone is a professional in his field and knows his discipline. I am confident that through using his book (which I've already began using)...and personal development, I will accomplish any goal I set out after concerning needing to use my HP12C financial Calculator. I very highly recommend this accomplishment by Mr. John Tirone. God Bless, W.D.Landrath...John 3:16 with Lev 17:11
Could have been better.

Honestly, I learn much more quickly from the two manuals that came with the calculator. The style of this book does not capture me. There is some inconsistency issue in the book and result in too much brain power to understand what was written. For Example, the author referring to 12 years and along the way he uses 144 months. Yes 12 x 12 = 144 but this require brain power to workout - the train of thought was haulted and double the time to understand what he was going on about. Another example, the author reference to 12c is also inconsistent. Like f CLX (CLX is white label on the key) in one page and later f FIN (this is the orange secondary label). It would be easier if he just uses the white label as reference consistently.
The book is in complete black and white and looking like it come from those day where I use to type my assignment with my apple 2e and bind it at the library. It is very boring and so hard to skim through the part that I already know. I lost track where the next section starts.
All in all, the content may be good but I fell asleep reading it. You will need alot of patience and alot of coffee.
This book made me money

I had loaned money to someone and the closing attorney had a lower amount due than I should have recieved. By pulling out Mr. Tirone's book and actually receiving some help from him by email (yes he does respond to email) I was able to pay for this book ans well as an Hp 12c with the extra money that I made!
Great book, fantastic (almost unheard of!) customer support!

Many an excellent review has already been posted here, so I really won't go into much other than I've got to face facts. This is a niche manual covering a niche product. The fact that we've even GOT a manual says something to me. The fact that it's an EXCELLENT manual is even better. But the fact that we have an excellent manual supported by someone that has a passion for education and genuinely wants you to be happy with your purchase is just jaw-dropping to me. We've become so ingrained with the thought that products are disposible or accept the fact that customer service is, well, not much in the 'service' department, that when you actually receive a fair product for a fair price it's a shock in 2008.
The manual (and addendum) are worth FAR more than the price charged. Mr. Tirone will have you understanding what HP should have put in their manuals years ago. Flashy it isn't. Rock solid it is.
No question to me at least, this is the manual that should have came with the calculator in the first place. I can't think of a higher compliment than that to extend to this product. Mr. Tirone is also a fantastic resource to have at your disposal should you need further explanation of concepts and applications.
I wish Amazon had 10 stars, I'd use them all.
This book is Great - just like its author !

The comment that follows is taken from the message I sent to John Tirone.
"Your book has become my new Best Friend. Everything the guys said about it
is true - It is Great! I only wish I knew about it prior to or during the
time I was struggling through the G series courses. On second thought it
may be better this way now I can really appreciate the Hp12c, as well as
learning how to apply it to my needs. Believe me I am a happy camper!"
What is also hard to believe, in this day and time, is how John has extended himself offering his support and assistance to us on the book and RE appraisal related issues.
John Tirone HP12c book is the Bible for the HP12c 
2007-08-02
John Tirone HP12c book is 'Awesome and Complete' and his customer support is beyond and above of any author.
After placing my order on line with Amazon, i was immediately contact by the author, John Tirone. He was courteous and helpful. Only after 3 days i received my book in the mail. The book was packed tightly in a padded envelop. The book arrived new and bigger than i had imagined. After my first inspection of the book, i was impressed with the amount of information and clarity that were presented. To my surprise, John included an updated spiral bound manual for the HP12c platinum/anniversary edition.
My first date with the book took me all the way to page 30 in a very short time. The book has ton of lessons with detailed instructions. The best part of the book for me is the 'intrepretation' followed each lesson. In this section John revealed his logic behind the keystroke, stacking, computation of the HP12c. Learning the HP12c cannot be more fun and easy. This book is a must have for all real estate and finance professionals. Too bad HP cannot include this book as a companion to theirs HP12c calculator.
The best thing about owning this book is that it includes John 24/7 customer service hotline. John will answer all your HP12c questions. John will answer non related HP12c questions as well...:). John is not selling books here, he is offering a global classroom and each of his book client is his lifetime registered student.
INCREDIBLE EDUCATIONAL TOOL TOPPED WITH UNSURPASSED CUSTOMER SUPPORT.
If you want to learn the HP12c, this is the holy grail of HP12c book.
for those HP12c owner still learning from the HP manual, don't waste more time on the HP12c manual/solution book or free HP online tutorial.
Thank you John. You've saved me time and money.
Just the refresher I was looking for!

I learned the hp12c back in the 80s for the IREM CPM program. Then the CCIM course was written for the hp10bII which is nowhere near the build quality of the hp12c. After burning through several of those hp10bII pieces of crap, I decided to go back to a hp12c to use as a backup to expensive software programs. This book is a great reference tool for any one in real estate. Although somewhat dated in its layout and appearance, who cares? It is a great book about the best calculator ever invented and is full of detailed financial examples and checks. Mr. Tirone communicated extensively with me by phone and email as I waffled between hp12c and hp17bII calculators and books. He is extremely friendly, cooperative, and supportive.
