Congrats - beautiful design

“Architects design buildings that kill people; engineers design buildings that make people want to kill themselves.”

While it may seem counterintuitive, having a specific tenant in mind when designing and marketing the proeprty is very important.

Depending on price, studios or 1-bedrooms can still get you a good return, but I suggest focusing on 4+ bedroom units and having a really special design to stand out in the market.

Yes, it's generally advisable to switch your home insurance policy to one specifically designed for rental properties once you convert your househack into a full rental property. 

You'd most likely have to look for a commercial unit, which would be more likely to have the card reading accessories you're talking about + they can keep up with the constant use, which residential units aren't designed for.

There is no secret sauce needed other than a really good budget, really good construction and really good design.

However, when I design my own house in the future, I plan to accomplish this in addition to other green energy features.

But those are nice cabins with more than one special factor: incredible views, high-end design, amenities.But I run numbers on potential short term rentals all day, and 4 out of 5 are less than 5% CoC.
