In the depreciation input find the entry for Property Number. Change 1 to 2, then press Ctrl and the down arrow to get to the next asset. Repeat. ....

OR did you want to duplicate all of the assets? 

1. Export https://accountants.intuit.com/support/en-us/help-article/import-export-data-files/exporting-depreci...

2. Import https://accountants.intuit.com/support/en-us/help-article/partnership/common-questions-fixed-asset-i...

I have not tried doing it in page22/Depreciation, but do it on a routine basis for 11/interest, 12/dividend, and 17/sales (for duplicate bank, investment, or property names, respectively).

Alt+A[dAta menu] | i[copy Information]

followed by

Alt+A[dAta menu] | O[paste cOpy]

to create <another one just like this> of whatever record you are on.

Again: UN-tested.  No idea if that is enabled in Depreciation page.

George's first answer actually just re-directs the asset from Property #1 to instead affect Property #2.

Having a copy of the asset (like "this house") gives you another one of them.

Note that duplicating them as described--either with his export/import or my copy/paste [if it works] would include things like date in service and vehicle miles, as well as Prior 179 and Prior Depreciation claimed on the original record.
