Viewing potential properties without a realtor?

[Zachary Wagner]

My wife and I are starting to search for multi-family investment opportunities in our area. We've been poking around on redfin, realtor, zillow, etc., and there are already several properties we're interested in.

I've reached out to the realtor we have worked with in the past for our primary residence about our interests. However, my wife and I are very eager to take a look at a couple properties in particular that we feel are especially good options and may sell soon.

Should we wait until we hear back from and can coordinate with our realtor, or should I contact the listing agents myself to see if they can set up showings in the next day or two.

Disadvantages/advantages to starting to view properties without our realtor?

Thanks!
