Hi @Karen Kushner
There while I do not know the specifics of your situation I can answer generally
1. The property needs to be placed in service before the end of the year and this will allow you to benefit from a cost seg
2. Was this property your primary residence?
3. Land cannot be depreciated but the building, land scaping and other capital expenses can be.
4. Bonus depreciation allows you to take all depreciation for items with a useful life of less than 20 years in a single year. The remaining Items will be depreciated based on the life span of the item and according to the depreciation schedule
5. A cost segregation study breaks the property into smaller pieces based on useful lifespan and shows what can be taken on an alternate depreciation schedule. Without a cost seg the property will remain on straight line depreciation.
Your strategy is possible but I would still recommend speaking with a CPA to ensure you understand depreciation recapture and intricacies of a 1031
