The last 2 BR in the MLS rented fro $550. A low purchase price does not necessarily translate into a decent ROI with the current condo fees. You may try a more expensive (relatively speaking) single family dwelling. It is easier to obtain a decent return without the condo fees.
If you want to be close to the beaches, from about $750 and up on an annual basis. Seasonal rates would be higher, starting at about $1100 per month. Click on the web reference below to search all properties available and call me, I would love to help!
