Real estate is a great investment because of the tax deductions, making it so you hardly pay tax on your revenue.  

The combined revenue as LTRs, however, would be about $3000/month.

I want my occupancy (and revenue) to be maximized so, for me, it's very important to have something unique that the other places don't have so my condos will stay rented throughout the low season and in case of a downturn in tourism.

I dont know how many units you are talking about, my biggest problem was tenants having easy access to me.I finally decided to use a software and got an internal property manager so moved away from it.Currently setting up the maintenance request portion of it, so will see how it goes.

OR it may be the spark needed to build out your next RE revenue strategy.  

Does anyone have experience with how much the annual revenue might be?

If your area is popular over Christmas, you could still get booked and with slashed prices you just lost some revenue.

Did you have any ratios or % gross revenue costs to just get some guidelines on whether the property makes sense as an str? 

In an oversimplified view, revenue of $1,000 and expenses of $1,000 offset to $0 and you made no profit...yet.

@Maegan Quaife, Of the 4 prongs of the Internal Rate of return 2 of them are very high for you - cash flow and amortization of the loan.
