Tom: Good afternoon. I have received your contact details from my colleague Anna.
Diana: Hello Tom, it's good to hear from you. Anna told me you will be in touch. How can I help you?
Tom: Actually, there are two things. First of all, my wife and I are looking for a flat. At the same time we want to sell our old flat.
Diana: I understand. Thank you for contacting me, I think I will be able to assist you. Are you looking for a flat to buy or to rent?
Tom: This is one of the things we've been discussing with my wife. What are the current trends? Which option do you suggest?
Diana: It depends on what you value more, it may sound obvious, but if you value stability more than flexibility, I would suggest you invest in buying a flat.
Tom: We were looking for something bigger than what we own now, but we may not have a budget for something we may need in the future.
Diana: In this case I would suggest maybe buying something smaller to rent and renting at the same time a small flat to save or buying something slightly below the budget, so you could save for later.
Tom: Thank you! This is a great advice!
Tom: I will talk to my wife, but for now, I think we could focus on buying something similar size.
Diana: How many rooms are you looking for?
Tom: Two bedrooms at least, joined kitchen and living room is fine as well.
Diana: Do you have any preferred neighbourhood?
Tom: Anywhere near the tube station within zone 3 is acceptable.
Diana: Thank you. What's your current budget?
Tom: We were thinking about £400 000. Would it be possible?
Diana: I think so. Would you accept a flat that needs to be renovated?
Tom: It depends on how much we can sell our flat for.
Diana: How much are you aiming for?
Tom: At least £300 000, it's in a very good condition, good neighbourhood and it has been renovated only a year ago.
Diana: Could you please send me some pictures? I would also gladly make an appointment with you.
Tom: That would be perfect!
Diana: Would Monday at 8 be acceptable?
Tom: Hm, I need to consult it with my wife, but so far it's all right.
