OH MY GOODNESS!!! 6 answers and no one answers the question! Ask a title company, get a realtor!? Why they don't just answer the question is beyond me.
In Texas, you can estimate your closing costs around 3% of the sales price (fees, prorated taxes, docs, etc), but most title companies have minimums and $25K may hit it. if you use buyer and sellers agents/realtors, you can throw in another 6%. So your closing costs will probably be around $750-$1,000, without a realtor, and up to $2,250 with one.
