How important is walk up (3rd floor of a building vs 1st)?

In the last two weeks we've rented a townhouse apartment in Manchester, a first floor apartment in Windsor, and have received multiple applications for our New Britain and East Hartford units (currently vetting tenants for those).

The only problem is that I want to tile the bathroom floor but I'm not sure what to do about the tenant living there as well since there's only one bathroom and doing the tile work would take a few days.

Granite counters in 1st floor unit (ideal for owner/occupant).

Families often choose to add on a 2nd floor rather than move and find a bigger house because they want to stay in this neighborhood.Anyone able to help me do the math or share a calculator that factors in the opportunity cost of taking the cashout ($364k equity, $45k realtor commission, closing costs, CapGains exclusion) vs holding for a rental (zero or negative cash flow but strong equity appreciation).

We were in a first floor unit. 

I happen to be renting out a unit in a high rise condo rent is 2,150-a month 2bed 2bath on the 2floor of a 30 floor building classified as A- built in 2001 with good amenities like valet, library, pool, gym, sauna, garage parking.

New electrical from the utility pole to every switch and outlet.All new plumbing.Opened the floor plan, new kitchen, new bath and new floor throughout.Added finish details and some nice interior color choices, at least, I think so...

Prefer the rooms on a different floor?
