No one does and after a while it can get tiring so you’ll want to control your own destiny by owning a home.Why flush rent payments down the toilet when you can build equity.

Why don’t you just flush $800,000 down the drain and buy a property that rents for $2,000/mo?

All tenants expect to pay market rent and receive annual rent increases Your good tenant discount is simply flushing profits down the drain.

Then the people that had been at work and not gotten the notice to not flush showed up..... 

The tenant responded, "when I flush, a little water comes out at the bottom."

The toilet should be the biggest obstacle for flushing anything, ie once it makes it through the toilet it should make it through the line just fine.

Outbuildings didn't have to be touched beyond basic clean out.I agree with others who have stated that plumbing and electrical can get you, but it's so worth working with a jack of all trades general contractor who knows her/his stuff and you know codes so you can give very specific direction and have them get the job done without having to use a full-fledged plumber.The following has nothing to do with your question about biggest expenses, but may save you big dollars in the long run:We were given some tips that have paid off: vacuum out your HVAC system to the best of your ability prior to inspection (inspectors see dirt or dust and they give you poor marks and tell potential buyers that a professional needs to be brought in to clean out the system); run Draino through your tub/shower drains (if you're leaving existing tub/shower in tact) prior to listing and test the drains to make sure there is good flow (we might or might not have used the tubs to clean paintbrushes, which resulted in REALLY slow drains); If you have a hand dug or shallow well, run bleach through it (lots of instructions online as to how to get bacteria out of the system when a hand dug well is involved) and flush the bleach immediately prior to inspection.I hope some of this helps. 

I still have plenty of money so my pot is fine to piss in and it flushes!

@Wayne Brooks  sitting through my CE on veterans day with about 40 RMLO's and being bored to tears since I do only private stuff ... it was clear that these rules are interpreted many different ways. and each lender and closer has taken different steps.this will all just have to flush out over time.

Even if you're flushing the toilets fine when inspecting the house, oftentimes the second a piece of toilet paper goes down that line, it hits the break and starts to clog up.
