Do you have any quant data to provide insights, like you provide on local housing markets?

Using any systems to manage the call influx, data tracking, etc...?

What to specifically pay attention to according to the tests?  

@Kenyon MooreI use the data from the tax assessor to do direct mail

Even so, when new tenants move into a brand new rehab, there are often bugs that get worked out in the first few months as they test all the new systems and find any problems.

These typically fall between 6-9 depending on who is evaluating and which parts of the country they derived their data from.  

Pete- obviously it's up to you, but I love having my own access to MLS.Not sure about your area, but between taking a pre-license class, state test, etc and then paying to join your local association and pay MLS dues, it could cost you $1,500-$2,000 or more to get started (at least in Florida).The nice thing is that you can set up a daily hot sheet for whatever area you desire that will show you all the newest listings and price changes.

Studying/ test / finding a brokerageHow is business?

But, as with everything don't lay all your eggs in 1 basket. try some other forms of advertisement, like Facebook, twitter, Instagram, craigslist, for example I don't have a lot of FB followers on my business page but, it get's me a lot of clicks to my website with a $5.00 boost campaign where I can collect data from buyers and sellers.

I personally like Listsource because they have some of the best, most reliable data out there.There are a number of direct mail options out there if you want to outsource.
