If you have a better comp you can certainly ask that it be considered, you can ask questions and certainly ask for explanations, but tactfully so as not to make it sound as if you are making any demand.

L/O are tricky here but your other explanation got the hamster wheel turning!

It sometimes gets some flak because Robert Kiyosaki is a guru and all that, but it contains a very good introductory explanation of how to think about money and investing.  

Thanks for the explanation!

Your explanation of the process is top tier on a high level of professionalism with assuming the sale and offering full disclosure up front so i've already gotten an amazing take away from you, thank you!

There are many reasons, but a couple explanations include the following.

If they can't get comfortable with the explanations I'm providing, they will likely require a 2nd appraisal.

I think I might have been to vague with my explanation. we talked about the fact that he's getting board with being a landlord, and he's on to note selling and buying, this process he's actually helping me out "or so it seems" until further noticeI've ran the numbers with a partner of mines and it comes out to be a great deal especially due to the fact I'm not putting any money out of pocket, and I'm getting the 4 % 30 year (at least i think) Account Closed where we have it writing up and with the current occupancy, its cash flows 2200 monthly - 714 mortgage 400 month electric, 40 a month water. and 1900 taxes a year.  

I think the calcs should be accompanied with explanations and directions in order to be of real value as teaching tools.  

@Chad Clanton   thanks for your explanation.
