It's not worth your mental health if it is bothering you that much.However, on the brighter side, you can learn so much from her demands/requests and how to balance tasks/management on which one to delegate/outsource versus to do it yourself.I always account this on operating cost.

Only viewed four properties, bid on two, closed on one.... agent couldn't have made much money at that price point, but his total time was very minimal... and I did buy him a nice tactical flashlight like mine!

Prior to meeting with the tenant at the rental unit, I gather my "move-out tool kit" (flashlight, 12 ft tape measure, 6 inch ruler that has big enough numbers to be seen in a photograph, camera, notebook & pen, disinfectant wipes, small handyman tool kit, step stool, mobile phone, copy of tenant move-in checklist, list of common charges).

To document the damage you know is there from the smell, record yourself walking the place in low light/dark while waving a blacklight flash light.  

Hi Robert,I'm not in the market for  a duplex in Pittsburgh, but I did a quick mockup of some of my thoughts about it.Just a little brighter, and some masonry and lighting to improve the curb appeal (a little).Looks like a Class C or D area.it looks like it may have had a store downstairs at one time.Zoning might allow a liquor store or something.Good Luck!

I show properties at night with a flashlight and on the fly.

This is my .410 gauge "flashlight"...it no longer works as a flashlight:) Nobody would ever suspect!

(I have a few basic tools such as: screw driver-Philips/flat, hammer, power drill, adjustable wrench, flash light, pliers, tape measure) I assume most would have air filters on hand?

Its the portfolio 8 led path light 8x brighter about $60 which is totally worth it.  

Delays and delays are adding to my holding costs.On a brighter note, have a showing this week for this property from a buyer who is very interested.
