Good to meet you.Color of the postcard does matter.On small cards the two colors are pink (2 times a year, Mothers Day and Breast Cancer Awareness Month) and yellow. 

Honestly, don't lose too many brain cells over this.

I am amazed that people dont call all of the folks in their cell phones and ask for opportunity.

Their MLS's use free template flyers to input info into.Your question is along the lines of " Would an agent pay a bunch of money for  a professional photo or shoot one for free on their cell phone that gets 80% of the way there?

However your cell phone is packed full of birds dogs who can help you find opportunities, so take advantage of your COI too.When you begin Direct Mail focus heavy on your list and Geo.

I can grab 60% of the cell numbers attached to a property address and 25% of email addresses.

Does anyone know which company it is that allows you to snap a photo of a house on your cell phone and instantly mail out a postcard to them?

I hate to put my personal cell or home number on any direct mail.

Because online shopping services like Amazon, which store consumer information, are using very strict verification processes, such as sending a text message, or a code to an email address before one can change/update anything.While this method may be a great way to may prevent fraud. it can also bring havoc to someone who may have changed cell phone number and/or email address several times since the first time they set up their account with Amazon, eBay, and so forth.Another scenario could be that the person who moved away is staying with someone who cannot place them on the mailing address, as it may cause an issue with the person they moved in with. 

Besides traditional marketing you would be surprised how many prospects and/or bird dogs are saved as contacts in your cell phone.Call everyone and let them know that after a lot of thought and careful consideration that you have decided to become a real estate investor and then ask them who they know who needs to sell a home.Happy House Hunting
