I am looking to do warranty deed - I am moving the deed from my personal name to LLC owned by me and no mortgage on the property.Will this result in any transfer taxes?

I typically look into the property tax and transfer records, which are all online to see what the property is currently assessed at.

My understanding is that these properties have already been foreclosed on with proper notices given and the deeds officially transferred to the county a few months ago.2) Redemption - My understanding based on the state laws the original owner could walk in tomorrow, hand them a pile of cash and get their deed back. 

Most locations do have some form of “transfer fees” on the real estate itself, which occurs at closing, typically paid by the seller.

Would it be necessary to transfer back to personal name. 

That is correct with FHA, the appraisal stays with the house for 6 months, so if this deal falls through and you get another FHA buyer, then that appraisal transfers to them. 

Would it be necessary to transfer back to personal name?

Ownership transfers to me.

Transfer taxes are the biggest at $2250.

And transfer your property into your LLC/SLLC via a legal trust that is a member of the LLC.
