@Michael Quarles I also agree that having them sign the contract the day of the appointment allows no time for "extra thinking"I am just trying to get an idea of what I would be most comfortable with. 

Always assume half. take that number and times it by the number of appointments you need to go on to gain a contract.

I'm doing exactly that now- partnering with a local investor (who I met at REIA) who is experienced w/ those types of deals.Have set up two different appointments on leads I received which I believe are very-possible sub2 deals, and he agreed after doing his own research.  

This takes maybe a minute or two.If I want to buy she sets an appointment and more importantly confirms their offer price.

No phone calls, no appointments, no offers, or no closed deals?  

@Michael Quarles Taking comps to the appointment is a great technique that I'll put in my arsenal.

Not to sound terrifying however please never use your name or personal home address and certainly tell someone where you're going to on appointments and have a safety plan.

Doctors appointments are a perfect example of motivation taking over reasoning.

There was a formula that stated that X amount of calls would lead to X amount of appointments which would lead to X amount of sales. 

In the old days I found it was make 9 offers get one deal. 3 appointments a day.
