When I searched "mortgage" just now, the first four results on the page were advertisements. The fifth and final result on the first page, of which only one line was actually visible without scrolling, was a mortgage calculator website. On the right side of the page there was another ad with graphical links to mortgage companies.
I guess for those queries it depends on lot on what the ad spend is in your particular locale, since you want those particular businesses to be close by. We certainly have plenty of lawyers and mortgage agents here in Kitchener, but perhaps they aren't big into advertising on Google.
Then there's a map. Of Seattle, because that's where Google thinks I am (it's off by a couple hundred miles), with mortgage-related businesses shown. Below that, we get to "People also ask" and finally, links that are not marked as advertisements.
On the right side of the screen I have links for Annaly Capital Management, Fannie Mae, Freddie Mac, AGNC Investment Corp, and Wells Fargo.
Writing this out made me think more seriously about DuckDuckGo. Going there and searching for "mortgage" is ... refreshing.
The ad targeting might be locale-specific, but the companies advertising aren't.
In the NY area, I also get 4 ads as the first results for "mortgage", from lendingtree, consumeradvocate.org, mortgage-loans.thetoptensites.com, and bankrate.com.
They may do geo-restriction just to reach the largest number of people with the smallest spend, or something like that.
The other person's point stands though, for many searches you don't get many non-ad results on the first page.
