Yes, I agree with my colleagues here. It's far less likely now than it was some years or even some months ago. BUT, not impossible. The rental market has been fairly profitable these days as many folks couldn't qualify for a mortgage due to the more stringent mortgage standards.
Now, the sales market is picking back up again and, as I write this, agents and buyers have to be quick on the draw to get an offer in on a property before another offer comes on the table!
You can always ask, but it would be a better use of your time to pursue properties that the owners actually WANT to rent.
