Ballpark % of Closing Costs for Cash Purchases?

[Account Closed]

Hello, using the BiggerPockets calculators, I'm trying to quickly evaluate properties to buy for cash to even see if they make any sense. The one area where I'm stuck is estimating Purchase Closing Cost when using the BiggerPockets calculators.  Is there a ballpark % of the purchase price that is conservative enough to basically cover all the closing costs that are typically involved in buying a property for cash?  I've been using 4% but not even sure if that's close.  Any help estimating would be appreciated.  Thank you.
