Some people keep a locked cabinet in their STR which is full of the normal consumable supplies (bath soap, dish soap, laundry soap, paper towels, azz wipe, light bulbs). 

(Old sewer pipes and invading tree roots don’t go well together!)

You can order a custom window to fit any opening.A clear plastic shower curtain does a great job of keeping the water off the window and letting the light in too.Be sure to make the window ledge at a steep enough angle to prevent anyone from using it as a shelf for soap or shampoo bottles and it will drain water really good if and when someone forgets to pull the curtain over the window.

There is NOTHING for a tenant to put shampoo on or soap.

Then going back to your root assertion that this Heather woman was a "plant" by virtue of her associations, this same argument makes Obama a "plant" by domestic terrorists and racist hate mongers - which is ridiculous.

They have a very shallow root system, and from those roots emerge shooters, which eventually become new aspen trees.

Has anyone experienced tree root damaging foundation/sewer pipes?  

The rod that works the pop-up stopper tends to catch any hair or fiber and combined with soap residue makes clogs. 

Some investors, such as myself, are choosing to rent their primary residence in San Diego and invest their capital in other markets, due to the low cash flow returns in SD, and the relatively low rent prices for a primary residence.That said, I am huge fan of the lifestyle in San Diego, and I'm still looking for ways to put down roots in this city that I love while not completely sabotaging my investment ability for the next 10 years.

I would wait for 2-3 months before making the purchase so you can use the renters money to pay for the entire shipment and analyze their spending trends and see what items they enjoy the most and best prices that would out compete those places. convenience things like toilet paper, tooth paste, tooth brushes, laundry detergent, soap, bounce could be an option, and then you have snacks, cold drinks, phone chargers, etc.
