For me acquisition costs vary widely depending on the type of financing, services needed and even the time of year and that's for properties all in the same geographic area.
Financing - origination fees, appraisals, points vary depending on the lender and type of loan
Legal - Title insurance is usually a percentage but the attorneys fees, recording fees seem to vary quite a bit especially if any kind of title issue comes up. In Georgia attorneys do closings not title companies so this probably varies by area. Also we pay stamp taxes to the government which I'm sure varies by area.
Services - If you get them, Inspection, Survey, Termite, rekeying etc.
Taxes - depending on the time of the year I pay prorated property taxes at closing
Having said that, I usually figure on 2-3%.
I usually use 3%-4% as a safe number.
Great question Bryan H. and awesome answer Jeff, Jason and Joe. Mahalo for sharing.
