Do sites ranking page 1 for local searches sell?

I am interested in what's possible on sites like flippa... Is there a market for the following types of sites?

1) local business sites optimized for local search?
2) local business sites ranking page 1 in local search?

If yes, where is a good place to find buyers? How much do they tend to sell for? What niche would be in demand, dentist lawyer, etc.?

Thanks in advance.

Great question. I'm also working on ranking a local website right now and would like to know the answer.

Managed to find an answer here:

I rent sites out vs. selling them. Even $300-500 a month adds up. Doesn't sound like a lot but its up to $6k a year. Do that 50-100 times (multiple sites for the same client and you're golden). Pick the service niches who profit more than your fee when they get 1 client. 1 deal and they're in the profit.
