We used Lawyers Settlement Service in Meredith
http://www.nhtitleclosings.com/ to close on our condo and we were very pleased with them and their paralegal Donna was great! We paid cash so no lenders were involved but in my experience the lender usually dictates who will do the closing and you can hire your own attorney if you wish to represent you.
As for a lender, we got a great rate for our primary residence in MA with Sovereign Bank but they have awful customer service and we've had so many issues with them that I've considered refinancing just to get away! It might be worth the extra cost to go with a small local bank that will be there to support you! Looks like Laconia Savings Bank is offering 30 year rates starting at 4.75%!!!
