LEGO Investor rating: WATCH

There's a very good chance that LEGO Tower Bridge 10214 will retire by the end of the year. This iconic set was first released in 2010. It's very rare to see a set as large as this one (4295 pieces) stick around for 8 years so now or in the very near future is a good time to buy the set before it disappears at RRP prices. 

The set itself is remarkable, as one of LEGO's iconic world buildings, and we think it will command a high price on the resale market. 

Some of the coolest facts about this set:

• Includes 4 miniature vehicles; a black London taxi, a traditional red double-decker bus, a yellow truck and a green automobile
• Completed model measures 40" (102 cm) long, 17" (45 cm) high and 10" (26 cm) wide
• Includes 4 miniature vehicles: a black London taxi, a yellow truck, green automobile and even a traditional red double-decker bus
• Features the iconic paired towers and a drawbridge that really opens and closes

It also complements LEGO Big Ben 10253 really well and the two together in a London city scene is a perfect way to build or buy the set. So while we rate LEGO Tower Bridge 10214 as WATCH, we think it'll be moving to a BUY rating very soon.

The Eiffel Tower is one of the world’s most popular landmarks, attracting millions of curious visitors from around the world each year. 

​LEGO's The Eiffel Tower set is a very popular model because of this. ​And here at LEGO Investor we think its popularity will last for years after its eventual retirement. 

Here's why we think it's one to watch:

LEGO 21019 is the only set from the Architecture series that was released in 2014 and is still on sale! That 4 years of shelf life means two things:

1. It's been an extremely popular set with LEGO selling lots of them, so there has been no reason to retire it (aka a cash cow). 

2. Very rarely does any LEGO stay in production for four long years, 

Once LEGO does decide to retire it (before Christmas 2018 to make way for the new sets in the series is a good bet), investors will want to try and pick up a few sets at RRP or on sale (£29.99 or below).

Though the long shelf life suggests lots of other resellers will have stocked up too, the enduring popularity of this set means you should be able to make a tidy profit over a 1-2 investment horizon. 

We see it gaining 5-10 per cent value annually  (yep, that's way higher than your bank is paying you on savings interest).
