the list comes up with hundreds of match's and I don't have the patients to scroll through them all..

You may not find a situation where you will cash flow very much (you may even still have to pay a couple hundred bucks/month) but at least you are now owning a property, not throwing a large chunk of your money away in rent (assuming you rent now), your tenants are paying down your mortgage, you are gaining equity each month and gaining tax benefits.

To be honest I did this back in 2009 with my NYC landlord, they raised rent at a time when I could get a larger place for a few hundred less per month...
