Still searching for the perfect sewer line, most have at least some imperfections even new construction.

People are imperfect and things like late payers is something you deal with in your approach to managing properties more-so than in the vetting process because if tenants were perfect most would be owners not renters.

Growing up, my mother and I were renters, and I vividly recall the gratitude we felt when a landlord took a chance on us, despite my mother's imperfect credit history.

He said it shows all the imperfections.

The sub floor I installed it on wasn't perfect, but only have very minor imperfections. 

A sprayer will need to be cleaned and you will likely use a brush and roller as well because the paint will not be the same everywhere.You will probably want to use flat on the ceilings to hide imperfections.

The floor is not super out of wack, more just some imperfections of chips and some hills, overall is it worth doing for what it's for?

Pace is a man and imperfect, however, he is helping so many people with the community he is building.

Thanks Tanner, I’m mostly interested in learning about construction so that when I view homes I have a general idea as to how much an imperfection, like a torn carpet, might cost.

Depending on what the line looks like (i.e. if it's just a small gap in a joint/imperfection in the line that the roots are growing in, and not that a whole section of the line has collapsed or anything like that) then you can probably try this first before replacing the line.
