I see this question a lot. I'd done hundreds of real estate transactions as a buyer, investor, agent, and real estate broker, and I still don't really know what everyone means by "investor-friendly title company".
You want a title company that will:
1. Follow the terms and conditions and timelines of your contract(s),
2. Perform a thorough title search,
3. Issue a title commitment for the required title insurance policies,
4. Hold and disburse escrowed funds as required by the contract and the transaction details,
5. Manage and close the transaction from start to finish, process the deed/title transfer and mortgages, and record the necessary documents.
But this is what they do for every single transaction, whether you are a first time retail home buyer, or a seasoned investor bringing them an assignment of contract and a purchase and sale agreement.
There's nothing particularly "investor friendly" about this. You just need a competent and reliable title company.
If in doubt, go with your local Fidelity National Title or Stewart Title office. Both are respected national brands operating in multiple states.
