Need Email Database for Local Townhome/Apartments Main Office

HI everyone,
I need to compile a database of email addresses for the Main Contact person for all Townhouses/Apartments/condo's etc. in my area and a few surrounding areas. I have looked into some software, but I only need this one time to distribute a marketing campaign, and don't wan to pay a large amount.

Is there Anything out there Free or inexpensive that will allow me to compile this quickly? Any recommendations are appreciated.
Thank you in advance

If you're willing to get your hands dirty and learn a little bit, there's AutoHotkey. I write scrapers in it all the time, and once upon a time, I wrote a script that pulled THOUSANDS of contact details for businesses on Yelp. So, it's entirely possible to make what you're looking for, but again, learning and work required.
