question-Brooklyn Buildings-What is the difference?

Pre war means built before World War II (early 1940s).
The rooms are usually bigger then post war buildings.

Yes, Arches posted a classic NYC brownstone, and quite a beautiful one IMO. They are almost always walk-ups, but I was once in one with a small elevator that was installed after the fact. Some very lucky and/or rich people will own a whole building. Most often, there is a separate apartment on each floor, with a common stairway leading to each apartment. Some of them also have an apartment at the basement level.
Also, like Arches said, the first building you posted is just a brick apartment building.
I'm a structural engineer, and I often find the older, pre-war buildings to be built much better than the newer buildings.

Most brownstones were originally built as single family homes in the 1800s but have since been divided into multiple units (approx 1 every floor or 2 per floor if they are studio apartments). More fortunate people may own an entire brownstone as a single family dwelling (worth millions of dollars), but many of these buildings still house 3-5 apartments. The best floors of a brownstone are generally the garden apartment (lowest level with access to a small backyard) and the Parlor floor (the first floor at the top of the main stoop with the highest ceilings). Occasionally these two floors are combined into a very nice and large apartment (usually occupied by the building's owner since it's so nice). Other apartments in a multi-unit brownstone are usually accessed by an internal staircase/hallway area.

The building photo you posted looks like a typical prewar multi-unit apartment building. I googled 6-10 clark street and looked at the listings at Awaye Realty. It looks like it's a walk-up building (they usually mention elevators if they have one) so a higher floor is less desirable (think groceries or furniture). But the location is fantastic. That part of Brooklyn Heights is really quite beautiful, safe and convenient via subways. It's definitely not a brownstone, but you would be surrounded by them.

Good luck.

Pre-war means before WWII? I never knew that...I always thought it meant before WWI. Just because it's made out to be something quasi-special but I don't think I've ever looked at an apartment in NYC built past 1920 or so...meaning they were ALL pre-war but weren't advertised as such. And they definitely didn't all have cool details or brick walls or whatever.

i think pre-war means before wwI, at least that's what i've been told.

From wiki, the answer to and source of much internet confusion:

"The term pre-war is usually applied to the most recent or significant war in a culture's history.

It is, however, often used for the period before World War I or the Interwar period before the outbreak of World War II, i.e. before 1939 or 1940.

In real estate the term refers to buildings from the (late) 1930s in the Functionalist or Art Deco styles."

This makes it nice and vague, don't it? That pre-Gulf War construction is something else!

:wtf:

Realtors lie. See the apartment yourself and do as much research as possible.

I have definitely seen post-WWII construction advertised as "pre-war." Presumably, if pushed to the wall over it, they would claim they meant pre-Gulf War. If a word doesn't have an iron-clad legal definition, you can be sure they will stretch it to the limit.
