Ok, after much reading and all the comments, yes, I have figured out that I need to do a separate schedule to calculate the basis of each property separately and then do a "Summary" 8824 capturing the combined amounts against the new property acquired.
So, next question, in calculating the adjusted basis, it says I have to include ALL depreciation taken - does that mean depreciation taken for things purchased on the relinquished properties, like carpet, appliance replacements, furniture (two of them were furnished airbnb types), etc? And what about the vehicle expenses/depreciation that I've allocated to each of those three relinquished properties? I will continue to use that same vehicle for the new one.
Thanks to everyone for all the assistance - MUCH appreciated!!
