Walking or driving around, although I don't do a whole lot of location shooting at this time. And I have never paid for a location.
Not to say that you can't get paid for the use of your property but you would have to treat it as a business which would include having business liability insurance if anything happens to the crew while on location. You would also need to advertise it, probably through direct mail to photogs who use locations such as yours (meaning a lot of work looking through the portfolios of NYC photogs) or mass mailing through mailing lists bought from photogs organizations at a premium price.
But before you do anything, you may want to think long and hard about what it's like to have 10-20 people showing up on shoot day at your house who all need to use your bathroom the whole day long...
Plus, depending on the type of shoot, they may need a room for make-up purposes, one or two more for dressing rooms, access to the kitchen for lunch preparation, the dining room for a place to eat, etc. Basically, they'll be all over the place. Are you ready for them?
Now, of course, I'm painting the worst case scenario but, let's be honest, photoshoots are not the best in a house you live in, lol.
