Each time that period is going to be about 2 weeks in a good scenario, but I could be wrong.Steps 1-5 will take likely 2 weeks alone if you are interviewing multiple agents.I don't know what the frequency is of deals falling out from offer being accepted until final inspection, (best I can find is a article stating nationally 3.9% of sales failed in 2016, up from 2.1% in 2015)  but it's a considerable pain for any seller to have to reboot that process trying to appease a single fickle buyer. 

So, charging higher rent and increasing the frequency of turnovers can actually net you LESS money than charging less.

Is the total number too insignificant to see any real results and should I ramp up my list number or frequency?

@Sharon VornholtSo I just jumped in to this thread looking for some more information on Direct mail frequency.

I usually consider the sending frequency in terms of using emails because too much is not always better.

Also, what is the frequency of mailings?

Frequency: How often will you contact them?

So the more times a seller understands that they have a choice the better.If you want to increase your success rate you'll need to increase both your frequency and presentation.If a prospect receives 4 completely different pieces of mail from you with different messages and contact info within a short period of time and 6 pieces from other investors the odds of generating a Lead hugely weigh in your favor.Also keep in mind the value of a touch.

I would suggest asking other users to see if they could share letters/postcards that worked for themYou must also plan the frequency of your campaign.

I’m sure there are several individual cleaners in your area that would love the flexibility and frequency of a quick and ongoing $40 gig.
