Good read...awesome that it's working out for you!
Here's an oceanfront condo where the owner was getting about 19K a year renting it himself short term before he just sold it (pending)...
In a previous Craigslist ad, he said his total expenses were around $7500 a year, so his profit was $11,500... HOA's are around $250 a month and includes everything except electric, which runs about $80 month. It's at Myrtle Beach Resort.
He'd rent long term in the off-season (Oct-March) to Canadian snow birds for $600 mo., and then $500-$1000 week during the 6 peak months.
I've owned oceanfront units over at Sands Ocean Club and they did around 15-17K with a management co(I could have done a little better I think with VRBO and similar sites). $320 HOA that included electric, water, cable TV, internet, and everything.
Sorry to the OP, didn't mean to hijack your thread
