Hi and welcome!
There will be differing views from each of the spectrum as veterans weigh in on this. From what I can gather, there are pro’s and con’s to each.
One of the FIRST things to hunt down is how much the local municipality is going to charge for hooking in laundry machines to their sewer. In some areas it does not matter and in others in can get into hundreds of thousands of dollars and can break the whole project.
That would be one of the first things to look at.
Best of luck with your hunting!
