I'd make sure just how much extra tax benefit will open up for you annually compared to the cost of the study.You are exactly right - a cost seg will get deferred in a 1031 exchange as long as the property you are purchasing is roughly the same components of things that were cost segregated.

Extra 4 months of carrying costs are up most of the margin.

If your average heating bill is $150, you may not collect enough in the winter months when the bill reaches $225 but you'll collect extra in the summer when it drops to $65.

I find tenants really appreciate that little extra touch on move in day.

In that case, using the cost segregation study this year might not be necessary because the extra depreciation would just increase your loss, which you might not be able to fully use right now.However, you have two options:Use the Cost Segregation Now: This would increase your loss this year, and you could carry forward the unused loss to offset future rental income.

If I need by some chance I need extra money I can fund it with money from my side business.

Manage their properties Provide welcome gifts/ goodie bags for their guests before check in Hauling extra supplies/ misc items to return to stores or other properties--Any other ideas that I can pitch to make myself more marketable?

Well, what would you do with that extra cash flow? 

So I did not pay extra for it, but chose it anyway over other places.

And if they don't deliver, you need a truck and an extra person.
