Somewhat similar, I stayed in grind houses for the most part and only went via agents once, in which I paid like $400/month for a place with pool, gated, perfect location just off 5th(main street), 100 yards from the beach. They have low and high seasons also so ofc that was in the off season. On avg id expect to be paying 600+ if you want somewhere nice.
Would recommend searching facebook marketplace for rentals in the area to see what the current market looks like during covid, imagine there is alot of good deals around.
