For example, they can see your wiring diagram and know you plan on using the right sized breakers and will not overload them, you have GFCI in the proper locations, smoke alarms will be installed in all the proper rooms, etc.5.  

And if the unit already smells of smoke, how will you prove if they are still smoking inside or not.Run it like a business and do what you have to do to protect your investment.

@Myo Thein suggest depending on value and equity either looking at other areas on BC to invest but by the time you travel, find something etc. it may have costed you thousands already.

I know the Austin market is smoking hot and even with cap gains I could stand to clear 300k after tax and expenses.

I spent about 10 hours a year on each unit, and when I travel I use a 24 hour handyman service.  

I have to travel about 5 hours round trip to get to either, but I usually spend from $1K to $5K per trip. 

And just to be more ambitious, this is the list of everything I want to do:- Clean all the junk and debris from the house and yard and demo the shed in back- Replace the roof and fix the gutters/soffits- Landscaping- Replace all the windows with double-pane vinyl windows- Replace all the floors in the house (ceramic tile for the kitchen/bath/laundry room, and vinyl plank for the living room and the upper level)- Re-do the bathroom with new everything -- plumbing, tub, shower surround, floor, sink/faucet, toilet, mirror, accessories- Re-do the kitchen with new cabinets, counter tops, and sink/faucet- Paint the entire interior (white ceilings, beige for walls, white for trim)- Replace all the light fixtures, outlets, and switches- Replace the front and back doors and put in new locks- Add smoke detectors and carbon monoxide detectors as required- Finish off the upper level (that was begun by someone else)I want my rehab budget to stay at or under $30,000 and I want to complete everything within 2 months from closing. 

If she refuses to stop smoking in your property, I would call the local housing authority and find a nearby property that does allow smoking.

They say the plumber says it might be a crack or leak and want to do a smoke test.

Managing an out of state property is a definite option for me, however it is very difficult to travel to different parts of the country just to look at possible investments.
