When shopping rates it is always your best bet to go with a solid broker

It depends on your location, size of property, purchase price, nightly rate you can get, your upkeep of the property, and many other factors.If your unit shows well in photos and if you build up some good reviews in the first months, and your pricing is reasonable, it will be consistently rented.We have 3 of them, and all less than 1 year so the jury is still out, but in our experience so far, the startup and ongoing costs have been higher than expected, but all are getting good reviews, so in year 2 (now that they are stable) we expect to do pretty well.You have to make sure your town allows it, and you have to decide if you will manage it yourself and take on that extra work (communicating with the guests and people who will clean/make repairs) or if you will hire a property manager, which can be expensive, upwards of 25%.

Is it rude if we start a pool to bet on the eviction date?

Best bet?  

If there is anyone in the Portland area who has experience with new construction of apartment buildings of this size, and would be willing to give up a little bit of their time I would love to buy you lunch / beer!  

Most consider betting on appreciation is speculation not investing.
