Deductions & credits

Thank you so much  @Carl 

Really appreciate your response 
the main house abd carriage house were on same purchase/deed/ loan 

 

- by tree work I mean we need to have trees cut down in the carriage house driveway. 

- do you recommend then consider as in law unit and prorate lawn , snow and other work ? 
- I only pay one insurance and taxes for the whole property. It is not itemized separately for carriage house and main house .. so I’ll just deduct this only as one item then?

- depreciation ; so how do I depreciate just the carriage house portion then ? Prorate it ? It doesn’t affect the main house then ?
