I am using bandit signs right now but the city will take them down fast.I can get 1 bench sign for $110 a month with a 1 year contract, this is on the busiest street in townI have done some mailings with zero success and thought about taking my direct mail money and doing bench signsI have done 3 mailings, the first one was 500 post cards with zero response to absentee land lords, the second was 500 to expired listings and all I got is calls from people who let me know there house sold or something else.The last mailing was to absentee landlord (yellow letter of 500) and I got 10 -15 calls but no deals I know them main thing with direct mail is to never give up and mail to the right people.

I'm toying with doing a direct mail postcard campaign for pre-foreclosures but I've been hearing that the response rate on those is pretty low.

Check the local laws to be sure you are not breaking them and maybe even have a chat with an Officer about the potential liability of your plan.An alternative might be post cards announcing your availability to the NBHD on certain days and ask if they would like to make an appointment with you.Twenty, thirty years from now I may be happy to see you...when the dementia has taken over and I say yeah come in, there are some issues in the basement you'd probably want to see...bwahahahaha!

Depending on the yellow postcard your response will be from 1/4% to 2% although 2% is rare. 

I'm thinking a postcard that blasts this, plus contact info, might be a good way to get referrals. 

Or is it worth the chance of sending a yellow letter/postcard/mail regardless and hope for the best?

Mix up your mail piece and consider using Postcards over YellowLetters if only able to send 1000.

Hi guys I just wanted to know if any investor in NYC uses yellow letters or post cards?
