Can landlord/property change unit after approval and payment of fees?
Without the specifics of the contract, as well as the specifics of the country/state/city you're moving to, it's hard to say what's legal.  But this also isn't law.se, so I'll answer this from the point of view of personal finance, and what you can/should do as next steps. Whenever paying an application fee or a deposit, you need to ensure that you have in writing exactly what you're applying for or putting a deposit in for.  Whether this is an apartment, a car, or a loan, before any money changes hands, you need to get in writing exactly what you're putting that money to. So for a car, you'd want to have the complete specifications - make, model, year, color, extra packages, and any relevant loan information if applicable.  You wouldn't just hand a dealer $2000 for "a Toyota Camry", you'd make sure it was specified which one, in writing, as well as the total you're expecting to pay.  Same for an apartment: you should have, in writing (email is fine) the specific unit you are putting a deposit for, and the specific rate you'll be paying, and the length of time the lease is for. This is to avoid a common tactic: bait and switch, which is what it looks like you've run into.  A company puts forth a "nice" model, everything looks good, you get far enough in that it seems like you're locked in - and then it turns out you're really getting a less nice model that's not as ideal as whatever you signed up for.  Now if you want to get what you originally signed up for you need to pay extra - presumably "something was wrong in the original ad", or something like that.  And all you can hear in the background is Darth Vader... "I am altering the deal. Pray I don't alter it any further." So; what do you do when you've been bait-and-switched? The best thing to do is typically to walk away. Try to get your application fee back; you may or may not be able to, but it's worth a shot, and even if you cannot, walk away anyway. Someone who is going to bait-and-switch on you is probably not going to be a good landlord; my guess is that rent is going to keep going up beyond the level of the market, and you probably can kiss your security deposit goodbye. Second, if walking away isn't practical for whatever reason, you can find out what the local laws are. Some locations (though very few, sadly) require advertised prices to be accurate; particularly the fact that they re-advertised the unit again for the same rate suggests they are falling afoul of that. You can ask around, search the internet, or best yet talk to a lawyer who specializes in this sort of thing; some of them will be willing to at least answer a few questions for free (hoping to score your business for an easy, profitable lawsuit). Be aware that it's not exactly a good situation to be in, to be suing your landlord; second only to suing your employer, in my opinion, in terms of bad things to do while hoping to continue the relationship.  Find an alternative as soon as you can if you go this route. In the future, pay a lot of attention to detail when making application fees.  Often the application fee is needed before you get into too much detail - but pick a location that has reasonable application fees, and no extras.  For example, in my area, it's typical to pay a $25 application fee, nonrefundable, to do the credit check and background check, and a refundable $100-$200 deposit to hold the unit while doing that; a place that asks for a non-refundable deposit is somewhere I'd simply not apply at all.
