Tenant said it's bad quality plastic.

Corporate housing is interesting - usually higher rents, all inclusive (utilities usually included) and everything paid by a company for longer than normal rental terms. (1 I looked at in NM $1800/mo rent included everything - elec, gas, cable, internet - paid by a hospital for a doctor doing elective surgery for 15 to 18 months at a time plus laundry income.

Another big mistake, I know…Since moving in back in April, he has paid his full rent on time twice - the first time was his first month rent and deposit... that was covered by his company.Within a week of moving in, his car was repo’d.Then, Covid hit and his job start date was delayed.Then, his first day on the job, he “thought he had a stroke,” and had to be cleared to go back to work.Then, when he was cleared to go back, he “fell out of his truck” messing up his knee.He was working in the office until he was cleared to work his actual job, again.Then, when he was cleared again... within a few days, he “slipped on a muddy rock and messed up his ankle...”At that point, he was considered a “safety risk” at his job, put on short term disability, and scheduled to have knee replacement surgery, which happened Monday.Last month, he was supposed to transfer the electric and gas into his name.

You don't know what you don't know.If you were having a surgery, would you rather have a doctor doing their first surgery or one with 100 similar surgeries as experience?

Question #2 - can I use a plastic bag for my moisture barrier when I replace the plywood or is there something more appropriate?
