Bit of an odd scenario:

SFR with 2 separate leases, each lease to occupy their respective half of the house (clearly laid out in each lease). The tenant in one half of the house has broke his lease and moved out. (A totally different issue). The second bathroom associated to this lease and this tenant who has vacated the premises needs to be remodeled. The second tenant renting the other half of the house does not want me to do the remodel on the second bathroom until he moves out (if he even does, yet another issue lol).

I am having multiple issues with the tenant still there, but luckily his lease ends 4/30/2022 (next month). 

So this is a 2 fold question I suppose:

1) Am I allowed to have the remodel done in this scenario?

2) Risk vs reward, do I do the remodel (if I can) now and make the tenant still there angry, or do I just wait until his lease has ended in 1 month? To me this issue is somewhat time sensitive as we plan on selling the house ASAP while the market is on fire and re invest the money into a duplex. (we stand to double the initial purchase price of the property if sold soon). So naturally the sooner the remodel is completed, the sooner I can list the house.

Thank you.
