Should I get a coin machine???

[Manaury Marte]

Hello BP family and friends. Since the pandemic started I have been lay off from my job and decided to rehab and 3 BR and 1 bathroom apartment that me and my dad own. The tenant the lived there for 7 years decidedly moved out and me and my dad are done with the rehab. I just find out that the electricity in the common area is conectes to the unit that we just rehabbed. Should I buy electric coin laundry machine and plug it from there or should I buy the regular ones...

Thank you in Avanced .
