Help with vacation rental analysis?

[Charles McCabe]

I've been watching out for possible Jersey Shore vacation rental deals for a while now and might have found one for which the numbers work.  Does anyone out there have experience analyzing such deals?  Looking for help predicting expenses (like maint/cap, insurance, cleaning, management, etc.) and revenue (I've computed my own rental season curve, but I'd love someone to validate that for me).

What I'm looking at is an MLS duplex that *I think* would rent for a total of $4300/wk at peak, at a least price of $519K.

Thanks,
