There are a number of listing agents who will not respond to an inquiry from a non agent.Also keep in mind that if the body of your email is the same on all 50, it could wind up in someone's spam folder...so a follow up call may be needed.

Hi, I am looking for a good structural engineer for a job in Harlem, New York Any good recommendation ?Thank you very much

If all you want is a warm body willing to babysit your house for free this is your guy. 

I’m going to be out of town but will need a warm body at the sale to make a few purchases.

I am a real estate agent with a year of experience in multi family,I may now have the opportunity to sell an automotive body shopthat will most likely be a re development or infill development,I can I outline what I have done so far and tell me what other issues I should be thinking about ?

Post it in the body/description, and even post some text on pictures, just in case they didn't read the description. 

The two gentlemen on the first floor are young able bodied who will have no problem taking out the bins each week. 

I know no body that is buying S/f 's at retail and renting them with good returns.

Allegedly he told the developer that he no longer cared about the money but he was going to break every bone in his body. 

It'll open your eyes to people's motives and how to "read" their body language.Then as you build up some more money and knowledge, buy yourself a nice little duplex or a few "cheap" houses.
