Is there a rule of thumb for estimating closing costs?

[Alex Baranov]

New investor, just starting out. Curious if there is a reasonably good rule of thumb for estimating both purchase and sale closing costs. For example, if I bought a single family home in PA for $100K, what would I incur in closing costs at time of purchase, and then again if I turned around and sold it for $100K again (obviously a hypothetical example)? Thanks in advance for your insights.
