Put several rental properties in one big loan... is this possible??

[Haixia Shi]

I figure this must be a fairly common problem. So I have seven rental properties (all SFRs in the same city but not exactly in the same place). Each one has a different interest rate and term and is serviced by a different lender. Now the properties have appreciated much over the past few years so I've got quite some equity tied up in these, but refinancing each one of them is going to be both time-consuming and expensive. Is it feasible to "consolidate" loans on separate rental properties into one big loan?
