How to build your sealed set while retaining the most value

I have a common dilemma that I'm sure others here have faced: I have a huge, sealed Lego inventory and in moments of weakness, I get the urge to build a set.  Staring for months at my rack of sealed Death Stars, Tumblers, and Sandcrawlers can break down the resistance of even the most hardened investor.

Anyway, once you've made the foolish decision to build a kit, I think there's some things you can do to preserve as much value as possible for later resale.  Here's a couple of thoughts and ideas:

1) Face it, you're going to lose some value.  This is unavoidable.  A sealed kit with unopened bags will always be worth more than a built kit, no matter what else you do.  If at all possible, try to buy the same kit already used, or with an open box, or some other variant.  Break the seals on your new kits as a last resort.   That said, here's some further ideas...

2) Obvious things are keep the box in as good a shape as you can (I store my opened boxes right along with my sealed kits), as well as the instructions.  If the kit includes stickers, bite the bullet and don't use them.  Keep all stickers on the sheet.  For things like UCS nameplates, you can use color xerox copies for display, keeping the stickers intact.  And this goes without saying: don't lose any parts or minifigs, including the few bits of extra parts.  

2a) When selecting a kit to build, if you have multiple in your collection, build the kit with the worst-shape box.  Also, obvious, but I carefully evaluate all my copies, and pick the one with the most damage, perhaps a broken seal, maybe some crease marks or a bit of crush-age.

3) Not so obvious things.  I carefully open each sealed bag with a pair of scissors (more on this, below), and I SAVE ALL THE BAGS.  Once the novelty has worn off and I decide to break down the kit, I re-use the bags.  Here's the tricky part: I also use the instructions to reverse-build the kit, and I carefully place the disassembled parts back into the original, numbered bags.  The goal is the next builder opens each, numbered bag and all the right parts (including extras) are present. This may seem excessive, but it certainly can't hurt value, and I think it will help on resale. 

3a) For those kits that have multiple bags for each, numbered step, I've often taken pics of the bag contents prior to build.  I'll try to re-package parts back into the same bags, but this isn't strictly accurate, and probably overkill.

4) All those tiny parts that come as extras in each bag?  When building, I put the extras back into the appropriate numbered bag, then store them with the box.  That way, the extra bits will be in the right place when I disassemble.

5) Make sure on disassembly that your kit is as clean as possible.  This can be tough if its gotten dusty.  I use soft-bristle brushes first to clean, followed by compressed air if needed.  As a last resort, I'll run parts in the sink with the sprayer and warm water, followed by towel-drying and the blowdryer to remove excess water.

6) If you cut open bags with scissors along the long, non-sealed edge (the part that's continuous and wraps around), I've found you get a beautiful, clean re-seal of the bag using clear packing tape.  I wrap the tape around the cut, then use scissors to trim the tape even with the sealed edge of the bag, top and bottom.  Harder to describe than show (and I could get a picture of this if anyone is interested).  When done, the bags look fantastic.  You're not going to fool anyone into thinking its a sealed set, but it will look like the best, built set you can sell.

7) Much of this effort is for naught if you don't take good pics of the kit, both built, and after disassembly.  Put these pics in your auction, if you're selling on eBay.  It works wonders, at least for the half-dozen sales I've done in this manner.

8] Maybe all this is overkill and I'm anal.  You're probably right.  None-the-less, the steps above won't hurt, and there's a bit of extra fun in disassembling kits carefully and getting them back to as close to as-recieved condition as you can.

 

BTW, the few sales I've had of kits given this treatment have all gone slightly above the usual resale prices on eBay, and 2 of those kits went for almost (within 5%) of new, sealed prices.

Thoughts?  What do you do when the urge to build strikes?  

 

Figure 1.  End result of foolish Lego investment decisions...

edit: 

Thought a few pictures might help illustrate my suggestions.  Here's a Volvo 42030 Loader I built, then disassembled.  Note the sealed bags.  This particular kit didn't have numbered bags, but you'll get the idea.  It's very hard to tell this has been opened and resealed, as you can see.  I find buyers really do respond to this care, and it doesn't take much effort.

Some good tips, thanks.

In general, time = money.  You probably will eke out a few extra dollars by saving the plastic bags and photo-documenting the whole process.  But the time you will spend doing that could be spent on other endeavors (building something else or buying/selling to make more $, for example).  This strategy to maximize value on used sets ultimately will take more time, so it's a matter of how much time you have and how you choose to spend it.  

(Also, refer back to the CAGR discussion on quick flip vs. long-term hold, and note that your stance there is that quick flipping is too much work.  So that is too much work, but saving & taking pictures of bags isn't?  Conclusion:  to each his own.)

To be fair, I didn't say QFLL was too much work.  I said long term hold compared to selling and then reinvesting in multiple sets was a better strategy for me.  That's not QFLL.  That's QFLL + rebuy of a worthy set near EOL at the same time, then rinse and repeat.  Quite a different circumstance.  I do occasionally QFLL when the opportunity arises; I sold quite a few Speed Champions this Spring at a reasonable markup.  

And for the record, what I've suggested doesn't take that much time.  It really doesn't.  I can break down and repack a set into original bags with just a bit more time than breaking down a set and putting them into ziplocks.  It might take me 30 minutes to break down a modular; I can do the same and repackage into bags in maybe 35 minutes.   Similarly, building a set doesn't take much longer.  It's about the planning and prep.  Having scissors and my digital camera handy to take pics.  The additional time investment is pretty much negligible.  I'd suggest you give it a try on a future kit, you'll find it's really not much more effort; it's more having the plan and knowing what you want to do (especially, carefully opening bags when you build and saving them - that's not a time sink, just a planning issue).

This thread makes me chuckle a bit. To each their own I guess, but I think you need to let yourself have fun sometimes without worrying about this kinda stuff so much. Sure you can go to great lengths to minimize your losses on opening a set but what's the point of having extra money if you never let yourself have fun with it? 

I only open and build sets that I know I will want to display for years to come. "Impulse" building is a dangerous thing and must be avoided. :) I almost always download the instructions and build using the computer. Not only does it keep the instructions minty, I think it's easier to see on the computer anyway. I agree on not applying stickers unless the stickers are an integral part of the set and would look weird displayed without them. I don't know about saving the plastic bags and rebagging using the instructions. I have never seen a set advertised like this on ebay and I don't see how it would affect the resell value much at all. If you advertise a complete set with all pieces, box, instructions, and stickers that's good enough for 99.9% of buyers.  

What about building the set inside the box, kind of like those ships in a bottle? I think that would probably help the resell value, as you could state that the seals are not intact, but the set was never taken out of the original box?

Just a thought...............

​I fully agree. I think it would be awesome to buy a used set that was bagged like a factory set, but I don't think it's worth the extra time and energy reverse building it. For that matter, I usually don't sell used sets with the box, even if I have them. I'm in the west coast, shipping a bigger used set with the box can be  3 x more than without. It depends on quite a few variables, but I haven't been able to get my money out of shipping w/ the original box. 

I like the idea of the downloaded instructions, I've never thought of doing that.

I Used to keep all the plastic bags but now don't bother.  I definitely don't use the stickers though if I know it's a set I have a decent probability of selling in the furture.

I have several sets in their boxes and ready to go.  I bought them for my son and I to build.  I wish I had your fortitude to wait and wait, but I just have always wanted some of these sets and can't wait to enjoy the fun of building them with my son!  I would rather live and enjoy the ride than miss that memory I guess.  I will take the hit on the value.  Of course, I will use all your knowledge and preserve all that I can (bags, boxes, spare parts, etc) in the meticulous manner you have suggested.  I am OCD so that is not a problem!

 

Thanks for the advice and post!

 

P.S.  I always download copies of the instructions from Lego and use color prints of those to build so the originals stay original.  I then seal the originals in vacuum bags for preservation.  Just a thought.
