I would set up an appointment to speak with a local mortgage officer. 

and on and on it goes)For Nov rent, I made an appointment with him on Thursday to pick up the rent check on Tuesday after work, which was technically 1 day after the grace period, but was going to forgive the late fees that time because arrangements had been made to pick it up...

I canceled my next day follow up appointment to see a hand specialist (I was hospitalized the week before due to a hand injury).

I would email Kyle and set up an appointment to talk to the team about joining.

I went out on a listing appointment and made them an offer they couldn't refuse.

so i usually ask who their underwriter is.. and in our market we are covered by all national underwriters so i have them send it to one of my closers here i use all the different underwriters.. no appointment and no charge LOL

I would suggest calling around and seeing if you can get a sit down appointment for an hour with an attorney to discuss the risks you face by going through with the purchase.

Quote from @Cortney Roberts: Give notification to Cure or Quit, a deadline of 72 hours, and set an inspection appointment for verification of compliance.

Do I need to make an appointment there?

I would go find a good local bank and make an appointment to meet.
