I think like anything else to some it will be seen as a + and to others a - , but you are the owner so think of it from the business side.

I'm not saying you're wrong, but if all else is good with condition and location, then it falls on pricing 

I have heard from few tenants that during their tenant onboarding they clearly mention tenants can pay the difference but when it comes to landlord they state something else.

Since the house is owned free and clear and has just been sitting there for 2 years since my uncle's death, my thought was that we would decide on a price let's say $625,000, I would pay for everything else and sell it.

-Sauna-Hot Tub-Patio/courtyard (large cement tiles on crushed bluestone with lighting, natural gas line to bbq)-Secondary patio off primary suite-Losing sq feet in the primary bedroom to enlarge the bathroom-High grade cabinets-Appliances with cabinet fronts-High end appliances (Viking/Miele instead of GE Cafe)-Outdoor shower (teak box walls with a dry well beneath the footprint)-Wiring for Cat6 to every room-Wiring for surround speakers (or including the speakers that are built into the walls)-Sonos whole-home audio system-Hardwired cameras (with on-site storage) to the exterior of the house-Smart features: thermostats are a given, but how about light fixtures, switches, aromatherapy, fans ... anything else?

Therefore, we either need to have a plan in place to have someone else manage them or to sell. 

What sort of business do you use it for, and do you think you might choose something else if you had a different business area/model?

This is an the city and the area around it is developing, so I will likely tear it down in a few years to build something else.

I know that is a lot to ask for but I don't have anyone else that is a real estate pro or has any experience with multi unit analysis. 1.

everyone else has already left great answers, I just want to add if you are purely a buy and hold investor: using bonus deprecation aggressively as early as possible is usually a great way to go.
