Thank you @PatriciaV very much for useful info.
'Section 179 deduction' options.
This 'Additional options available only if original use of property begins with you' means, the rental property was first used by me for personal use before putting into rental market?
I still wonder why i don't see significant difference in tax owed when i deduct all 9K improvement now or partial.
May be I hit some limit something for this year and can carry over next year?
