Attic ventilation is critical for not only summer cooling performance but also the longevity of the structure of your house.
Using a power drill and paddle attachment mechanizes the job of stirring paint, but it can cause splatters. One way to solve the problem is to use a paper plate. Punch a hole in the center of the plate and push the end of the paddle attachment through the hole before chucking it into your drill. Then hold the plate down over the open can while stirring.
Earnest money is money put down to demonstrate your seriousness about buying a home. It must be substantial enough to demonstrate good faith and is usually between 1-5% of the purchase price (though the amount can vary with local customs and conditions). If your offer is accepted, the earnest money becomes part of your down payment or closing costs. If the offer is rejected, your money is returned to you. If you back out of a deal, you must forfeit the entire amount.
