If the main drain gets clogged, you had three families flushing their toilets into it so you can't pin the clog on any of them.

I recently received the pest & home inspection report and there is faulty grades and the beams supporting floor joists are sagging in between pier blocks with cellulose debris to be removed(major foundation issue), no attic access, door bell didn't work, no ventilation in crawl space, leaking drain line underneath tub, faucet leaks, 2 drawer fronts are broken at bottom of closet, bathroom closet won't latch closed, door in between living room and front porch wouldn't open (I assume this is why the agent had the lock box house key on the back door and used only the back door for showings), most all windows wouldn't open (painted closed during rehab) and missing screens, electrical for entire home was only 100 amps instead of the standard 120/220 or 200/220 (assumed this is why all major appliances were unplugged).

When I finally got to check the inside once it was listed, there were no ceilings on the first floor and the electric wiring was hanging low it could get caught around your neck.Yes, just a couple of true stories, that are not the commonly heard tales of concrete or plaster being flushed into the drains.

I've had termites, sweating slabs with no plumbing leaks, broken drain pipes, missing HVAC units, copper stolen from under vacant property, properties red tagged by the county, accelerated mortgages because of due on sale clauses, pets that did 35K of damage, and so many other things. 

It can be flipping houses, selling something on trademe, anything that brings you cash to pay the shortfall.The good news is with the left wing stupidity going on in NZ we will see rents rise faster than ever before so your negative drain will reduce quickly.

., drains installed backwards and not properly sloped, the corners of the roof not nailed down to the trim, foam installed  and painted over along gaps between the trim and roof where it should be sealed etc.)

I just had some maintenance & repairs done to the house:- $220 to replace A/C drain pan and overflow plug.- $85 for a "Spring A/C system check".- $1050 to replace a 40-gallon hot water heater (in the attic).Last year:$ 450 to replace fan motor and capacitor in Condensing unit outside.How do I know if those are fair costs?  

After you've seen some of the worst REOs (think: cement poured in all the drains, all the freakin copper ripped on, no evidence of any HVAC equipment, etc.) the worn-out houses you see from mom & pop sellers will look like GOLD.

We loved being able to more easily relocate things with this Ranch floor plan and full basement (so could move plumbing around, etc. much easier than working with our current 2 story home where you have to really plan to make sure you can connect up with a drain line, etc. running up from the basement--as an example there had to use a laundry chute as a chase for water/drain/and electric to move laundry from the basement to the 2nd floor).
