Zoning and Back Taxes in Baltimore City

[Tiesha M.]

Hello, I have 3 questions.

Can someone tell me how I can find out what the zoning is for the neighborhood where I am looking to purchase a house in Baltimore city? Also, can you confirm whether or not title insurance checks to make sure there are no back taxes on a property? Also, what happens if the property does have back taxes, some other kind of lien, or other title issue?

Thanks for any insight you can give!
