I have a follow-up question that is somewhat related; how do you handle the objection of the cash buyer wanting an address, and to schedule a viewing of a property.

He literally stands over me to prevent people from placing objects in my mouth during a medical crisis.

I would assume you would have a title objection so doing your due diligence on the title side will take the longest amount of time, but you will have to do very little of it. 

With these two items in hand--which didn't come from you, by the way, they came from objective third parties--you now have the information and leverage needed to adjust the deal so that it truly works.  

I don't listen to them because there's honestly no objective way to verify them.  

I can't guarantee you will do that well, but certainly a 25% bump within one year is a reasonable objective. 

As for the quantity to begin mailing to, I wouldn't go below 1000 leads.

Learn the questions to ask, learn how to overcome objections and you'll be better off than many agents since you're already buying leads or OK with doing so.You've done rentals so hopefully you know the market.

That market study should be an objective look at the project. 

What is your objective.
