Compare at least three lenders and ask each for a written loan estimate before you choose.

The health grade says whether a bank or credit union is financially sound; it says nothing about service, which is what the reviews below are for.
Attorneys customarily handle closings in Illinois. State transfer tax of $0.50 per $500 plus a county tax of $0.25 per $500, usually paid by the seller; Chicago adds $3.75 per $500 paid by the buyer and $1.50 per $500 paid by the seller, and many suburbs levy their own stamps.
