I closed on my primary residence in May and just got a letter stating that there is a leak in a shower and they are demanding $25k by the end of next week.  

Something as simple as a plumbing leak or a dishwasher replacement will eat that up in no time.

Since this is a IRA plan (self directed), how are funds withdrawn to pay for, say, a roof leak repair?  

@Greg Scott hit the nail on the head for me.You say the roof is good for another 10 years, what if the other owner gets a leak or just thinks the roof needs replaced now?

Gas company is called and they find that the entire house could have blown up since gas had been leaking for a week.

Most of the time, the PM would not fix things until it breaks (like water heater leaking to downstairs unit, more problems coming later.)Only landlords would care their own properties more, and willing to have more maintenance before it breaks.

If you notice a leak or running toilet contact us for an early maintenance inspection."

It was leaking from the water heater connection and destroyed a lot of the dry wall with water damage.

Watch the water meter and inspect for leaks,, I'd check the meter occasionally when your at the building to see if the dial is spinning when no one is home,, you'll know you have a leak then.

The toilet also worked perfectly, this crack did not even affect the functionality or need to buy new parts for the entire toilet ($400) and then the installation ($400)-$2700 because he claimed oil leaks on driveway were from us, but in the letter of itemized damages withheld from our deposit, he told us he "verbally instructed" us to park our cars off the driveway (which i don't remember him doing) BUT in the lease he says "“Tenant parking may be reassigned another on site/on premises area of the property at the discretion of the landlord, and any such assignment shall be issued in writing and & shall become effective immediately upon receipt of written notice to Tenants from Landlord.” which he never told us in writing, and he probably does not have proof indicating it was us.-$100 per hole and $50 for paint to repair two quarter sized holes on the stairway for removing a gate we have never even seen on the property or knew existed (he is telling us we caused the holes by removing this gate) if anything, we wanted a gate for the dog and would have never removed it. but we seriously never knew of this gate ever existing, never mind removed it.-$350 for removal and disposal of broken toilet, remove and disposal of oil and clean up materials, and storage of items (trash left out for trash pick up day on the CURBSIDE that "interfered with his storage at the property")Basically, we have done nothing since receiving the letter on August 12.
