Breaking the quote into what's behind it: forming the LLC is mostly a form, and the state filing fee is separate and runs anywhere from about $50 to several hundred depending on the state. The operating agreement is where drafting time actually goes, because it says who owns what, how decisions get made, and what happens when a member dies or wants out. A generic template will cover the easy years. The deeds are short documents with consequences, and the choice between a warranty deed and a quitclaim affects what you've promised and can affect your existing owner's title policy coverage. Coordination usually means ordering a title check for liens, getting the recording done correctly, and dating everything in the right order.
$1,900 for that, in most markets, is an ordinary number rather than a bargain or a gouge. Recording fees and any transfer tax are on top, and whether a transfer to your own single member LLC is exempt from transfer tax varies by state, sometimes by county.
The thing that bites people who do this themselves: your mortgages almost certainly contain a due-on-sale clause that treats a transfer of title as a triggering event. Lenders often don't act on it, and there are federal protections for certain transfers that may or may not fit your facts. That's a question for your attorney and for your servicer in writing, not for a forum consensus.
Also call your insurance agent before the deed records. The landlord policy has to name the new owner or a claim gets ugly, and the premium can change when the named insured does.
