Why would you get the 1br instead of the 2br lockout?
1) It cost lesss & has lower MF.
2) You only travel as a couple and don't need a 2 bdm.
3) You are going to use it to trade with II online, and you know that you can often trade into a 2 bdm. with a 1 bdm., doing an online exchange.
Is there better trading with a 1br than a 2br?
If you always need to exchange into a 2 bdm., then you should buy a 2 bdm., because to put in an on-going request with II for a 2 bdm., you must deposit a 2 bdm.
Couldn't you rent out both the 1br and lockout for a better trade?
Renting and trading are two entirely different things. Depositing a 2 bdm. with II won't necessarily get you a better quality
resort, but it will give you more opportunity to exchange into a 2 bdm.
