- If the ad doesn't list dates and times when the apartment will be shown, you phone up the landlord and make an appointment.
- You go and see the apartment. Obviously you will be in competition with other applicants.
- Talk to the landlord and make a good impression -- do whatever is needed to make the owner pick you.
- If you are interested in renting, you write down your contact details in the applicant book.
- The landlord will go home and consider the applicants and phone up the lucky winner.
- The landlord may require a credit assessment to determine your financial situation. Some landlords require references from earlier tenancies.
- You meet the landlord to sign a formal lease (Scandinavian countries are pretty strict about landlord/tenant rights) and get the keys.
When I was renting in NYC, things were different. None of the places I rented (which I found on Craigslist) would have open house dates; instead, you would make a personal appointment with the landlord. Also, landlords seemed to prefer email.
