My ideal property is one where some or all of these major systems behind the walls or hidden in utility closets are brand spankin' new, but all the cosmetic stuff (the easy and inexpensive stuff that you can see and adds the most value) is just awful, worn, dirty, dated, cluttered, and smelling of cat pee and cigarette smoke.

Also check your local codes, they may require upgrades like interconnected smoke detectors and AFCI "Arc fault" breakers.

Our current rules detail things such as inoperable vehicles, trailers, quiet hours, smoking policy to cover vaping and marijuana usage, exception to subletting in extreme circumstance, waterbeds.

Everything goes through cycles; interest rates, affordability, rents, supply of housing, cap rates, rental vs home ownership etc. 

I have a discounted building supply store In my area.

Shrug it off, she found something better/cuter/cheaper and is just blowing smoke to justify her position.

Install new toilet, wax seal and water supply line.

Try HD Supply in Santa Ana for basic exterior doors.

I'm also concerned about the long term water supply.

Sorry charlie....the smoke screen is easy to see through.
