No one told me how hard it was to rent a condo

FU Miami I'm so frustrated. My realtor keeps getting told that the homeowner wants to hold off to get more offers or that they want $100-200 above the listing price, and most recently we were tuned away because my boyfriend doesn't have a job in Miami... we are moving there... I have proof of over $100,000 in available grad school loans and we both have a score of over 740-760. The semester starts on the 11th, and I have no idea where I'm going to live. I just wanted to vent real quick thanks, reddit lol
