What I’ve done is purchase it through and LLC than transfer the title to your personal name before the refi.

You and your title company may have to work to get them removed or settled.Governmental liens like other tax liens, city demo liens, city lawn mowing liens, IRS liens, treasury liens, federal terrorism liens, etc, don't get wiped out.

Or will a title company help with that?

For a 10-unit building I purchased in April 2021 I paid: 1% - lender fees (appraisal fee is 70% of the fee) 3% - title services 

I have created an LLC and plan to transfer the property title to the LLC.  

I own vacant land in CA and would like to transfer title to my TX LLC.

Honestly, I have been an investor, broker and flipper for more than 30  years in Texas and have never once used or needed a lawyer outside of a title company

Her credit score and your income should be sufficient.A social security number is not just for credit rating; it is for identity verification.

Like maybe work with the same title company?

I've got a QI and he is getting all the documents he needs from my realtor and title company.
