You need to be constantly be making minor adjustments and changes to build presence over time.

If you really want to invest in this city, you have to do your research because Pittsburgh is composed of several towns, some areas are great to invest and some aren't.

I love that we have created a presence so powerful that our competition is paying for part of our advertising budget.

This may create a "presence" for the agent by putting a lot of signs up, but it doesn't do anything for you as a seller.

Warehouse: Will these be in more demand with companies creating distribution centers for their ecommerce businesses as opposed to having a larger retail presence?

Cold calling/call centers/ paid leads was something we did a lot of and it worked well enough as one lead source among many, but we found in order to scale efficiently past a certain level it was important to focus more on generating inbound leads as much as possible which we did through consistently asking for referrals, brand building, web presence/ SEO/ content, email marketing, advertising both online and off, media coverage, social media, events/shows/speaking engagements, traditional/ offline networking, direct mail, etc.

Lots of discounts due to the national presence.  

Rather than record, we would like to be alerted to any intruder's presence in a property. 

Others will preach bandit signs but I’m against those as most areas make it illegal and I never recommend an investor take an illegal route just to make money.I think having an internet presence with your own website and getting that website in front of as many potential home sellers as possible is likely going to be your best bang for the back and the highest close percentage as “motivated home sellers” are the name of the game and when they are contacting YOU rather than the other way around, you have won half the battle.Hope that helps you sir and answers your questions. 

Similar attempts would be Facebook adds and other internet presence.
