If you're lucky, it's hard to mark time during the Summer.

Time just passes, with vacations and beach days and long, lazy nights.

So here's one midsummer marker: The changing of the (Junior) Guards. Session 1 has wrapped up with its celebratory competition, the Taplin relays. A new session starts Monday.

And then, at some point, the kids start complaining that everywhere they go, there are "back to school" sales. Not to worry, little ones, there's plenty more sunny days ahead.

(See DigMB's photo gallery from last week's Taplin relays here.)

Sand Section

209 15th (3br/2ba, 1275 sqft.) is a dated, older house with some decent views from the existing 2-story structure.

The location is both the pro and the con. There's no getting away from the fact that 15th/Manhattan Ave. is one of the busier parts of town, just a few doors down from Highland. On the other hand, this means downtown's pleasures are right outside your front door.

This listing raises the question of what the value of a half lot by itself might be in this location. More from the official description:

"Gems like this do not come along often. Immaculately maintained, this home offers spectacular coastline views to the south as well as Catalina. Two bedrooms on the 2nd level with kitchen, living room and cozy wood burning fireplace. 1st level has bedroom, kitchenette and access to tranquil back patio area. Live in it, rent it, or build your dream home..."

209 15th starts at $2.299M and is open Sun. from 2-5pm.

433 21st (3br/4ba, 1925 sqft.) is a newer (2009) TH with views. More from the official description:

"This beautiful townhome boast[s] amazing ocean and whitewater views as well as Palos Verdes views. Distressed walnut floors throughout with with a great open floorplan which makes this home perfect for entertaining. This Chef's kitchen has all Viking appliances with a 6 burner stove, walk in pantry and custom cabinetry with enormous storage."

"[S]olid wood doors throughout, built-in bookcase in living room, U Line wine refrigerator, copper sink in wet bar and powder room, copper gutters on the exterior, built in surround sound, large ocean view patio off master, 6 skylights upstairs and an outdoor shower."

433 21st starts at $2.99M and is open Sun. from 2-4pm.

Tree Section

3100 Palm (4br/3ba, 3350 sqft.) is an 80s original running along a corner lot, with a middle entry and garage off to one side. This gives it an appealing facade to the world, although the setup leaves no real yard. (Two patios suffice.) 

All common rooms are downstairs and all 4 bedrooms are up. Just about everything would probably get an update from the next owner. More from the official description:

"[A] classic family home with great curb appeal, a fantastic floor plan, and wonderful sun exposure! This home features four large bedrooms, all upstairs, as well as a spacious 3 car garage. Downstairs is comprised of a cozy family room with a fireplace and french doors that open to a very sunny and large patio. Also downstairs is a formal dining room, and a formal living room with a fireplace and 3 sets of french doors that open to another great South facing patio. The home was built in the early 1980’s. It has been cared for greatly, very well maintained but not overly upgraded from its original build. This is a perfect opportunity for a new owner to come in and take a great home with a great floor plan and put their personal touch on it. Some upgrades that have been made: New roof-concrete shingle, newer heater, newer kitchen appliances (stainless steel) some hardwood floors."

3100 Palm starts at $2.399M and is open Sun. from 2-4pm. 

East MB

207 S. Redondo (5br/6ba, 4425 sqft.) is truly something completely different.

A sleekly modern home with estate-like ambitions, it is actually located along a fairly busy street and would be easy to miss.

To get a grand, central entry, two separate garages are stashed to either side of the lot. Step inside and large living room with high ceilings beckons, opening to a spacious, green, well-landscaped yard. One guest bedroom is off to one side, while the large, open kitchen and big family room are off to the other. Four more bedrooms are upstairs.

The style, across the board, is definitely an acquired taste. More from the official description:

"This home will amaze with architectural details throughout and luxurious features to create a modern space that is still inviting and warm. Windows and French doors throughout the house create a bright and airy feeling, and the professionally landscaped yard and garden can be accessed from the living room, formal dining room, guest room, and the huge family room. This home is built to entertain with an incredible kitchen that opens to the family room. The kitchen boasts custom crafted cabinets, Sub Zero and Viking appliances, a huge center island, and a breakfast area. There are chiseled edged travertine floors and maple hardwood throughout the house as well as 3 fireplaces and 5 bedrooms, each with an en suite bath. The master suite has a huge walk-in closet and a nook that can be used as a nursery/sitting room/exercise room/office... This house is full of unexpected, wonderful refinements that make it incredibly unique. There is no other house on the market like it. It is truly a must-see."

207 South Redondo starts at $2.828M and is open Sun. from 1-4pm.

Prime lots in the Tree Section have been hitting $2M and a touch above.

It was only a matter of time before the American Martyrs area asserted itself (again) with an even higher high.

Now the sale of 608 14th has done exactly that.

The dated, 4br, 3000-ish sqft. house is fine, but it's the 5800 sqft. plot of land that's got the real value here.

Specifically, the market said: $2.950M. The sale closed this week.

Call it the American Martyrs neighborhood's first $3-million-dollar lot.

As the listing launched 5 weeks ago in June, they weren't necessarily pushing the ceiling too high. The asking price was $2.7M.

But competition and must-have properties means new, ever-higher prices must be paid.

We can't really find anything like 608 14th in very recent…

At a time when everything's selling and everything's hitting new highs, why not the 2006-built townhome complex over at 1202 & 1208 Tennyson?

This week, with the sale of 1208 Tennyson #3 (3br/3ba, 1750 sqft.), we see a sale price $100K higher than any public-market sale in the complex over 2+ years.

It was $985K, per the newly closed MLS sale.

Tax records, however, show that this sale eclipsed the highest-ever sale in the complex by just $10K. That was at 1202 Tennyson #2, an off-market sale that closed in late April at $975K and was just recorded officially last month.

The most recent public-market sale was at 1202 Tennyson #1 (3br/3ba, 1750 sqft.) at $880K in Sept. 2013.

Interestingly, that same 1202 unit #1 had also set the high-water mark for the…

It's a happy day for folks who like toys. 

The Tesla Model S now comes with – or can be retrofitted with – a new option, the "ludicrous" mode, which speeds the electric car's acceleration from 0-to-60 to just 2.8 seconds. It's like "having your own private roller coaster," says Elon Musk.

That car already flies. This was an upgrade that absolutely no one needed. Kudos to Tesla for recognizing that little things like "cost" and "necessity" sometimes have no relevance if the question is: Should we do this? It's kind of cool.

Maybe what we like most is the truth-in-advertising aspect. This irrelevant but fun $10K upgrade is actually called "ludicrous" by the big boss. This is how they are marketing it.

What we're watching for: The first local real estate…
