How many properties will you look at before you buy?

[James De Silva]

I've been walking around a lot with real estate agents of late, and I always go look at properties that I'm genuinely interested in buying. However, I don't always make offers (and for those I do make offers on, I don't always get accepted). I feel a little bad getting my realtor to organize getting me into all those properties without actually buying any.

Generally, for those who have many rentals or flips, how many do you tend to look through before buying? Which extends out to the general question of, how many properties do you look at in an area before you feel comfortable with knowing the general state of an area.
