If you are bringing the electric up to code the garbage disposal should have it's own circuit.

Code for new living space has been 7' ceiling heights for a while.

These corrections will involve using the Change of Accounting Method Form 3115, in accordance with section 481A of the Internal Revenue Code, for depreciation adjustments totaling $127,493."

Please feel free to use code VENI324 when upgrading to get your investing career going!

Unfortunately given the zip codes that you like, those units start with $800+ for single family homes.
