Need to replace hot water heater in Section 8 duplex.. Tank vs. tankless?

[John S.]

I'm almost done closing on a duplex (Long Island, NY) with Section 8 tenants. Each side of the duplex has 3 bedrooms, 2.5 bathrooms, washer/dryer, and dishwasher.

Each unit has a family of 5 living in it.

Would it make more sense to replace the hot water heater with a tank or a tankless setup?

1st it is a water heater,  not a hot water heater. I used to say this wrong as well till my contractor corrected me.

It's a rental, just put in a standard tank water heater unless these are very high end units.
