I have multiple single tenants to hedge any one going dark.

Remove wallpaper, prep, prime, and paint to the color of your liking.In this price we are including the paint and whatever is needed to prep. 

Painted with neutral colors.

That doesn't mean look at things with rose-colored glasses.

There is a jut out wall where the fireplace is, and I am considering painting it black or dark grey (and the rest of the walls white).

Great resource, and as an ex-Clevelander, I generally agree with the color codes.

Some of your photos seem small and dark - I'd either retake them or adjust the brightness with some photo editing software.

Hi BP fam,What exterior paint colors are you using on small MF in Florida?

Hi Apurva,53 units -- It would be smart to talk to an Architect who does multi-family (In your general area) about the cost of doing a restyle as well as colors.Especially if you choose a Hardie (Fiber Cement type) product.With Hardie (Type) products, read the upkeep instructions, some require re-applying the joint sealers (factor that into your maintenance budget).Also with Hardie (Type) products there is a service life to the color...some come pre-colored, some your contractors must paint on site, (some require priming of cuts when installed)---talk to the Architect about the maintenance schedule and the CAPEX for this.Hardie makes big sheets of this for multi-family that Architects can use for visual effect and ease of installation.With 53 units--springing for an Architect to help with this would be intelligent.Good Luck!

You'll dramatically improve your chances for success if you have a GC invested in the projects overall successYou'll also want to get a good realtor who can advise on whats popular in your market for finishes, color schemes, ect  Last but not least, find a great home stager and stage the home prior to selling.
