@Jared Baker Hi Jared, I believe it is totally up to you and your situation.
I started out physically looking at properties first, but our market is pretty hot right now and I'm only starting out so my price point was around 60k with limited rehab (which is like the ultimate golden egg that lots of investors are looking for). I lost quite a few offers to cash buyers (I was purchasing through a local bank).
I switched it up with the help of my agent and started putting in offers with a 10 day inspection contingency period (this rule may change based on your state?) which I could THEN look at the house if/once they accepted our offer to decide if we wanted to back out or not. I may not have all cash but I could at least try to be the first offer in!
We did make sure to check out as much on the internet as possible such as local crime rates on Trulia, google street maps for checking out the neighborhood, etc. We both work 9-5 corporate jobs and my partner takes night classes M-Th, and trying to physically see each property before putting in an offer was going to take us wayyy too long.
