I'm not a salesperson by nature but I can rent apartments. I use these methods:
"Let's go look at your apartment!"
"Will your furniture fit here?"
"Do you like this apartment?"
"Isn't this nice?"
I get their head nodding with me...they are saying yes! I also know EVERY SINGLE THING about my community and tell them. How far it is to dining, how big the tv nook is, everything about the heat, hot water, quirks, how awesome the staff is....etc.
And then when I get them back in the office:
" Would you like to put a deposit on that apartment?" or "Would you like to apply for that apartment?"
and if they say no they have to think:
"I'd be happy to hold it for 24 hours for you, would that be helpful?"
and if they say not right now:
"I only have ONE apartment like that available for your time frame, so let me know as soon as you decide."
And sometimes if I'm feeling really zesty I'll tell them if they don't rent it I'll rent it to someone else and they'll be sorry.
Depends on how much I like the person and if I have that rapport.
Also even if you feel like they hate the place ask them to rent. I have often been SHOCKED that someone I felt no vibes from got out their check book when I asked them for a deposit.
