Asbestos cover up in basement advice

[Alex Kleynshvag]

Hey guys, after reading two books from the bigger pockets family in the last couple of weeks I realized this might be a great place to come for some advice. Thanks ahead to anyone who can help. 

I recently got some new tenants that have been nothing but a headache with demands. I think it was my own fault at first for submitting to all of their petty issues and making them feel like they can keep asking for a million different things. It has definitely stretched my budged a bit thin but thankfully I haven't heard much from them up until this week again. 

the original lease did not have a clause for a washer dryer, but I told him I could happily install one in the basement for an extra $50 a month. I was able to find a great deal for an amazing set and to get them installed. now they are telling me that there is lead in the basement and they also want that covered up before they keep going down there. Now I understand that it is obviously not safe to be around that stuff and it needs to be covered up in time no matter what. But I'm simply not ready to spend the money at the moment to cover up a full basement just so they can do laundry down there. I was looking up the containment paint, and it cost $500 for 5 gallons. would it be too much of me to ask them to pay for the paint if I did the labor? Or is this something that's souly my responsibility? at this point I'm ready to just close the basement and tell them they need to find a washer dryer somewhere else and take the hit in the meantime until I can get enough money scraped together to get the basement done. We have not written up a new lease yet with the washer dryer included so there is no stipulation stating that I owe them as such. Thanks ahead anyone and everyone
