If it's a condo, there almost certainly is a "neighborhood association" with lots of rules and restrictions. A tenant normally would be responsible for complying with all those rules in addition to anything in a lease/rental contract.
Having done so once, inadvertently, I would refuse to reside in anyplace where there is an "association" and "restrictive covenants," but that might not be a viable option in the area in question.
I would urge that the existence of any "covenants" that might be impled but not necessarily spelled out in a contract should be carefully examined, and that anyone considering a sublet in a "planned community" (i.e. condo) consider that the "association" can change the rules - at residents/tenants expense - on the whim of the minority willing to show up at the (excruciatingly boring) meetings for the thrill of imposing their prejudices on all those living near them.
It should not be necessary to post a deposit without first seeing the complete contract. The "exotic" arrangements to (supposedly) assure that your money will be refunded if you decline to sign once you see the complete terms is meant to be reassuring, but does have similarities to Nigerian-style letters I've seen.
The person offering the place for rent isn't risking anything by sending a copy of the contract, so the person considering renting shouldn't have to "post a bond" in order to see what is being offered.
Before renting in a "condo" situation, I would personally demand to see a full and complete copy of the "association rules" - with amendments - before even looking at the lease/rental contract.
