This is the best book out there for tax information on rental and vacation properties - bar none. Is very well written and easy to read. NOLO press is well respected in the tech industry and this book is no exception. They publish a new version every year and I get a new copy myself about every other year. Amazon always has it in stock.
This book is written by the same author as the rental property tax guide above (Stephen Fishman) and is also excellent. Mr. Fishman covers the basics of home office/small office topics in the landlord book above. This one simply goes deeper and would apply to other business activities as well. There are other ones out there certainly. These are just two that cover their topics well, are put out by a respected publisher, and are easy to read. Again, Amazon carries it and this one comes as a Kindle version as well.
