That stuff is a great allternative to lino, Carpet. I installed some in my Moms house instead of carpet. Its easier for her to clean, cuts down on allergens, and brightens up the room.
I tried laying it down over the carpet, thinking it would act as a padding, Wrong. I had to take it back up, remove the carpet, and re-install it.
I also thought about mobile homes when I started out, They was cheap, Like 20k here in MA. But I just couldnt do it. I opted to buy a 2 family instead. Btw, Those same mobile homes now sell for 150K in MA. It would have been a nice investment, But again, My house is worth that much more now too. Again, Nice job.
