... My calculator coughed up $12,880 as the minimum FHA down pay on $368K and $13,125 as the minimum down pay on.
If you put down a $1,000 deposit when you wrote the offer. - That would have been part of the $12,880. Leaving you to pay an additional $11,880 at the close of escrow.
More on commission. Probably Not. In residential sales the seller pays the entire commission to both his own agent and to the buyers agent, almost always.
Buyers have other closing costs that buyers must pay OR get someone else to pay them. That sounds lke that is what the 3% from sellers most likely was to pay your loan origination fee, loan processing fee, loan underwriting fee. Any other loan fees. You may have gotten closing statement credit back out of the 3% for your appraisal, credit bureau report and home inspection. The 3% may have paid for some recording fees, some escrow fee, notary fee, Title insurance fee.
You also had to pay for a years insurance policy upfront and put something aside for the property taxes.
Clearly closing costs can be be as high as a down payment.
Many consumers, especially first time buyers, do not realize this.
Even repeat buyers forget how many and how much is put out in fees.
Although house prices have dropped drastically, fees and prepaid expenses such as insurance have not.
