We're looking for units that could attract a quality tenant, and one that may stay for awhile, so we look for things like dishwashers, laundry, decent storage in the kitchen, etc.

Shortly after I found out its a Single Room Occupancy(SRO) with communal kitchens(2 floors and 1 kitchens on each floor).

I will do some upgrading to the property as far as bathrooms and kitchens go.

Also does anyone have approximate number to get the house ready (furniture, electronics, kitchen supplies, etc.)?

Out of 12 appliances, we had a warrantee repair on a dishwasher and a warrantee replacement on a fridge.

We added a bathroom and kitchen in the basement on one side creating a 1/1.

Marble, stainless steel appliances, really nice kitchen backsplashes, nice hardwood flooring, etc.

When my long term renters move out (getting married, nursing home, etc) I offer to buy all their furniture, appliances, electronics, utensils, etc. 

I bought the furniture, appliances, decor, kitchen utensils, etc... from my friend as a separate deal, used it to airbnb without much effort, took great care of the property for the duration of my ownership.
