I posted this a little while ago and it went away quickly...
I have not seen a breakdown for calculating closing costs mentioned in any of the threads, just estimates or a range. I found this interesting. TTS explained to me that closing costs are based on the purchase price - figured like this:
$3000-$7000 = $400 closing cost
$7001-$10,000 = $425 closing cost
each $2000 over $10,000 adds $25 to the $425 (i.e. $12-14,000 = $475 c.c.)
They did not give me an under $3000 (didn't ask), perhaps $375. Not sure if this is consistent with all resales, but should be at least close.
