I would like to transfer title to a LLC at closing.

My insight as to how to best proceed may be of value to a buyer or seller or both, but that value can not be justified beyond the usual and customary cost associated in transferring title.

Disclosing borrower details is confidential information so the banker has other issues.Being ahead of the competition, understanding economic effects of what may happen is just good business.Unless you obtained the information from a confidential source you don't really have any ethical issues I see. :)

If so you might be able to set up a solo 401k, then transfer the money by a legal sleight of hand.

Part of the 10% of rents you would pay them is to transfer that risk to them. 

My accountant advised me to buy and rehab a flip in an S Corp, and then if I keep it, deed it over to the LLC and do an asset transfer in QuickBooks.

Through some networking (and prior to knowing about this site) I transferred management to another company.  

I haven't met with my accountant yet but I am going to pose the same question to him and see what my options are for making this transfer as beneficial as possible. 

And last point - the only concern that I have with refi'ing is that in MD (specifically Baltimore) we have to pay transfer and redecoration tax on re-fis to the tune of 2.5% for investment property.

Well, I signed on the bottom line and now I am in the process of transferring them into my name.
