It still has the ability to input time blocks, of course.

Cast Iron drain and waste lines typically have a 50 - 60 year life.

So they now own a house that is rented and the rent covers the mortgage payment by a ration of 1.25:1 or so and they have 5k extra in their pockets and their Heloc money, which they only needed 75k - 80k of - so 100k HELOC should be plenty - was enough. to get through the lifecycle.Do not let them drain their equity from primary and just sink it into a project. 

Sometimes they get deleted or blocked.  

@Ricardo SerranoThere are cap variations from city block to city block.

It helps you build the building blocks of owning real estate.

That gives me a nice buffer.The house I would be buying is 3500+ Sq ft just about one block away from a college.

I think it can be a good starting block if there is cashflow.

So I’ve since blocked off the third floor on one side and rented it as a 1 BR for now. but when the other side leaves eventually I’m starting to lean towards raising the ground grade 28” so that the total drop is less than 20’and then I’ll knock down some walls and make the whole 3rd floor attached only to that last unit so that the whole area can use the stairs and that window as second egress. 

But since this is consistent I'd also consider an actual plumbing drain stack leak.
