depreciation on property out of service and then placing it back in service

We placed a property for short term rental use and have been depreciating it. We have a situation, where we can no longer run it as business but place it as long term rental

 

For the duration of Business :

Depreciate the property as we use. It was placed in service with costs basis of say 10000$

Close it out as a personal use property (how?). 

Total depreciation  so far assume (10000$)

 

 

For long term rental (schedule E):

How do I depreciate the property now?

Basically do we restart the cost basis (10000$). Or the new cost basis will be Original cost basis minus te depreciated amount i.e. (90000$). Or something else?

 

I do have to do this anyways, for 2021 as it will continue as long term rental
