So I applied to this apartment and this was on the application form.

If my application is approved, I agree to the following concerning the rental process and the move-in process:

"ll give NextGene RM LLC one full month’s rent as security deposit and all application fees along with all documentation requied. I will sign, along with all people named on the lease, the lease and pay last month’s rent within two weeks of the date that this statement is signed. All funds for initial move-in (first month, last month, security deposit and application fees) must be in certified fund (money order, bank check, certified check), NO personal checks. If I fail to do any of the above, NextGene RM LLC has the right to, and will, put the property back on the market for lease to another party and keep my deposit (one full month’s rent) as liquidated damages (a non itemized sum to cover any and all loses)."

Is it legal for me to still have to pay him security deposit if I decided not to go with the apartment after my application was accepted?
