I’ve read several books/posts/blogs on tax benefits for RE investors, and even contacted a couple of CPAs who are active here on BP (even read their book), and besides poor communication skills, I was told that they couldn’t help me due to my high income and one of them referred me to a “larger “ practice but didn’t explain how that larger practice could help me!

Since you are being represented by counsel, all further communication must be in writing".

Obviously paper is the best way, but our magistrate accepts any form or communication to the resident to notify them.
