Shouldn't the unit that caused the leak be responsible?

I recently closed on a deal which carried a huge water bill because there was a leak from a pipe burst that happened during the winter.

The roof did have some leaks but have been repaired with a new roof.

This will help you calm some noise.My final point and perspective on your situation is you won't get rich your first deal and try to find a basic but producing property that won't break you if you need to fix a furnace, rood leak, etc... feep free to connect with me if you're still having issues and want a peer to grow with instead of comparing yourself to BP members on their 1000th deal.

Water leaks when bathtub is filled upstairs (legit issue – fixed by plumber)2. 

If your rental has a small fire, small leak, small rodent infestation during an extended vacancy and you decide to sell out of same or just plain discouragement, you really have quite a large/expensive long distance project getting it up to marketing condition and holding while selling.

If there is an unusual spike in water usage, it points to either a water leak, water waste or unauthorized occupants having moved in.

It always costs more than you think, learn as you go, always do what you think, even with surprises, you dont want to install floors and then find out the windows are leaking.

We found out the additional tenants due to higher water bill (not because of leaking).Now the lease is up.
