I have a unique situation; I have two units in my home one in the basement and one in the upstairs area. I was renovating to soundproof between the two units however, my lower unit where the renovation was happening was booked prior to me being able to block it off for the renovation. I had a one-week overlap where I would not be able to put the tenants into the lower unit. My solution was to block my upper unit and place them there until the renovation was finished, this was for 11 days, and they are staying for 10 weeks.
They have now been moved into the lower unit and I was able to get in and clean the upper unit. Prior to them checking in, I placed a brand new carpet in the upper unit; this carpet now has stains, considering there was only one set of guests in the unit I know where the stain has come from. When I reached out to them about it, they of course said the stains were there before, and made sure to let me know about other stains on a chair and the sofa (which I already knew about and agreed they were there before). I told them the carpet was brand new for when they got there so the stains could not have been there. They still insist they did not spill anything or cause any stains and are now trying to blame the AC repairperson or the people who came in to set up exterior cameras for the units.
I guess my question is, if I cannot get these stains out, should I be billing them during their stay or after they check out in 9 weeks. I just put a brand new mattress and box spring and sofabed in the lower unit and I am now a bit concerned, if they are that careless in not taking precautions to ensure items are not damaged will there be any additional damage to the new pieces I just purchased.
Suggestions, much appreciated.
