There are multiple ways to deal with the problem, but the easiest on this kind of floor is to mop the floor in an oxalic acid solution (oxalic acid is the key ingredient in Bar Keepers Friend but you can buy 100% crystals of it online through Amazon).

Lots of bars, restaurants, nightlife, etc.

Profit per unit must be incredibly small.Disagreement is the foundational tenant of American Freedom, so is respect and this response is, even if 100% correct on every data point, the single most disrespectful response I have ever read, bar none.

In the thought of if I could have my living experience be whatever I wanted...what would it look like.I came up with this list: Barber shop / Salon pallor, Car wash center, neighborhood grocery story (with good produce, beer/wine, premade but fresh over ready meals, and all my hygiene needs, on site bar or restaurant, community gathering area, a co-working space with small offices I could rent if need but a shared space also, a lap swimming pool, a real deal gym (not a hotel gym), sauna, on site laundry service (offered at a premium), and on site cleaning crew (additional cost of course) to clean my place.All of these things would be set up as additional sources of revenue for the apartment some that are directly operated others that just lease out space (like the salon parlor or something)Structurally it could look something like this: Sub basement: Lap pool / locker rooms / saunaBasement: Full real deal gym (anytime fitness level type) - could be directly operated or space leasedFirst floor: The amenities floor - could be directly operated or space leased2nd or third floor: Shared co-working space (residents get a discount and are priortized but its still open to the public for a cost)All floors above are living space.Has anyone ever though of this before?

This is how we keep the bar in this industry so low. 

Even with an existing wet bar and 1/2 bath, the conversation still cost us about ~$40k with us doing much of the work. 

@Lydia Bar I think the whitehall and northampton markets are great as far as rentals; they are strong working class renters areas.

.*)I'd recommend looking for a townhouse, row home, SFH, etc. that will allow you to have a mother-in-law suite in the basement or elsewhere, that you can add a wet bar and some smaller appliances for a renter (a range + stove can be tough permit-wise, but think air fryer, really nice combo small countertop convection oven, etc).

Should I just click on the “connect” bar for you?
