Ensure your HML is cool with this first, of course. 

You remember I make it my business to ensure that you get (or sell) the best house (or: sell for the most amount of money) and that I build my business based on your happiness and your referrals.

The Allegheny County Real Estate office produces a CD every quarter of all the sales in the county for the last three months (along with loads of property information).I use this data to see what's happening in the areas that I care about.  

The MLS is a different subject and for a another discussion.What is your source for this data? 

How do I ensure a contractor doesnt go over budget or time?

That's where I am; last year I brought in assistance to help with the owner statement data entry and managing getting the income/expenses into the system that we use for tracking.

Well you can take it with a grain of salt but at the end of the day it is just a data source.

Listsource.com - they are a data provider to the real estate and mortgage industries.  

They need a solid data connection in order to work well.  

Given the fluctuations and difficulties of all markets, I am able to reassess and modify certain objectives, to ensure they are achieved successfully.
