Is all of the paperwork and title correct?  

Seller agent disclosed today that the seller is filing for bankruptcy.I am already in escrow.Besides the checks that the title company will do, is there any additional steps I should take to make sure that this house is not subject to repossession by any creditors?

Your QI for the 1031 takes title to the property before you. 

I have a mortgage (2.5M) on a residential property located in the state of HI, titled in my personal name. 

Possible, yes, but you'll be looking at $5k-$6k in lender fees plus title fees, prepaids and escrows and a higher rate. $75k is a little easier to find and slightly lower rates/fees. 

You run title.

There is of course the agents, the brokers, the mortgage and lending side, the title companies but also the whole construction side would be part of real estate.

Quote from @David Ramirez: Call remodeled comps in the area that has been bought and sold within a year Especially for this method, you can paste the addresses in propwire and look in the chain of title to see the last owner before it was sold after being fixed up.

Another big one would be $3367 in Lender's Title insurance.

with a flip, a firm majority of lenders on the permanent refinance side require a minimum of 6 months of title seasoning.
