Masking tape can serve as temporary pulls on new cabinet doors so you can open them without digging fingernails into a fresh finish. Make a tab and stick the other end over the door top onto the back. Tape can also be used as an edge protector for tool edges, or as a quick clamp for edge splinters that need to be glued down. It's also handy for marking locations for furniture hardware.
If you lock in a mortgage rate, make sure the expiration date leaves enough time to complete the real estate closing. The flood of home purchases and refinancings has created major processing delays, so if there is any question about the processing time, or if you seem to be cutting it close, you may want to pay a little more for a longer lock-in period rather than risk losing your rate.
