There will be a dishwasher in the kitchen.

@Dawn Brenengen ok thank you for the tip.

You’ll need to sell some food, sandwiches, muffins, etc  too I would think....coolers, display cases/coolers, dishes, dishwashers, supplies, costs for labor, rent, utilities, insurance, licenses, permits, inspections, etc, etc.

Thank you @Dawn Brenengen for you insight!

@Dawn Brenengen Thank you for the encouragement!

Thank you for your answer Dawn. 

They'll call it a solid "B" area when it's a "C-" area; they'll say it has great space for the price, but the rooms are all chopped up and not very usable; they'll say it has great amenities, but those amenities are a 30 year old dishwasher and a central hvac system that groans and clanks when it turns on.

I did offer him a gradual increase and even offer to repaint the apartment, install new flooring, and add a dishwasher but his reply was "I don't want any changes, just leave me on the same price that i'm paying in the last 35 years".His 30 days notice was for Nov 1st. and was served on 09.28.18.

(Well, it would be once the 6-plexes are fully rented.)Also consider what you have to maintain for each property:Office: 1 Roof6-plexes: 2 RoofsOffice: 4 HVAC units6-plexes: 12 furnaces + 12 AC window unitsOffice: 2 kitchenettes (Fridge, sink)6-plexes: 12 full kitchens (Above, plus range/oven, vent/hood, dishwasher, etc.)Office: 4 bathrooms6-plexes: 12 bathroomsA couple more confounding factors: The office building is built in 2005 and located in a suburb of a major metropolitan area currently experiencing substantial growth.
