Depends how you define "looked at". I skimmed through hundreds of properties on MLS. I did quick calculations on 50 or so until I had a good sense for the area. I did more in depth calculations on maybe 20-25 to decide if they were worth visiting. I visited a half dozen before buying one.
It's a numbers game as everyone else is suggesting. You didn't mention which strategy you were pursuing but I'm assuming it's rentals. Here's what I found works.
1. Paper at desk quick evaluation. 100
2. Detailed at desk evaluation of 20
3. Site visit for about 5. First time i leave my desk.
@Richard Lovering I have yet to secure my first deal, but I’m looking at 5-10 a day and putting them through a tool I built to quickly calculate ROI and returns. I’ve gone to look at 5 or 6 so far and have definitely appreciated the learning opportunity it’s presented — I’m getting more comfortable with assessing what would be a viable opportunity from my desk before wasting my and my realtor’s time.
