I am not sure if the frequency with which he has shown me normal or not.

Many behave in a manner similar to a smoke or CO detector and emit a periodic warning "beep" when the battery begins to fail - the frequency may increase as the point of failure approaches.

By the more prevalent than anything else.In roughly the same frequency I see REI signs would be ones talking about buying junk cars, buying gold/jewelry, and "singles" websites.These are usually on polls like REI signs or in the ground like in the medians on highway on/off ramps.

(i.e. amount, frequency, for how long).

My preference is for multi family because of the reduced vacancy risk, but just know that multi's do tend to have a higher frequency of turnover (renters stay in houses longer), so expenses will be higher.

Then slow down your mail frequency dropping back to postcards quarterly, likely mailing each prospect 8 times before stopping but maybe sooner depending on results of the broader lists.Going to use yellowletters and Michael Quarles for the mailing.

I've never heard of this, I just checked the fannie mae selling guide and there's no reference to frequency or limitation of applications.

And what is the frequency you plan on mailing that same list?

To increase response rate AND the quality of your leads, consider these two factors: 1) FREQUENCY - hit that group monthly and you'll see response rate rise over time.

There is no particular correlation between math and finance.There absolutely is a reason for this.Mathematicians develop computer algorithms/mathematical formulas that are used in high frequency trading (HFT).http://en.wikipedia.org/wiki/High-frequency_trading
