Hi. Austin is one of the most competitive rental and sales markets in the US. My advice is decide on an agent you can work closely with as, yes, the market does change daily. If you need to move in 20 days from now, you ought to be actively engaged in this way right now as this is the window where you will have the best chance at success. All fees are paid by the landlord for an agent to assist you, and I highly recommend against using the big sites like this to search vs the up to the minute accurate info on MLS as you do not have a lot of room for error with the clock ticking. However, I recommend you find an agent you feel good about working with and feel they will work hard for you, commit to them, and then engage it heavily to get what you want. Our occupancy rates are through the rood and the area you stipulate is also very competitive. Find someone you can trust and let them guide you through the process. I mostly focus on sales but do take on the occasional tenant is you still need help. If not, I wish you the best of luck!
