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. 

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.

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.

We want to run another 203K, this time converting a basment to ADU (Basically have to do everything: Permit, design, Egresses, full kitchen build, level concrete floors) as well as spruce up the main level.  

I suppose if someone just had a traditional homeowners and umbrella policy there could be exclusions for rentals, but any decent agent can find a policy package designed for rentals.

He’s told me he’ll help my design the fix and flip to meet the latest market trends. 

We for example, are OK with "Cabin Style" under this brand-new definition - since this issues comes up frequently:Properties with “Cabin Design (Style)” per appraisalreport are eligible if Foundation Walls = Concrete Block Roof Surface = Metal or Shingles Heating = FWA Interior Walls = Drywall or Plaster
