I've allowed pets in my STR for five years and haven't had any problems except some extra cleaning a couple times, which was paid for by the guest. 

The entire project took around 3 months with EVERY square in minus the electrical( some added) being gutted and renewed.

I just had a vacancy come up in the middle of a fourplex escrow and the seller had the unit re-rented in under a week for $50/more per month. 6) Yes it's hot, but with individual metering the landlord doesn't foot the electric bill 7) Yes the market is competitive here, but mostly for 3/4 unit properties.

Quote from @Deandre Brown: When analyzing deals, a few additional factors I like to consider are whether the electric and gas utilities are charged per unit or as a single expense.

The moderators have since cleaned it up.

Like the push to get tiny houses accepted and zoning changed,   a "cleanly well run rooming house" business model has yet to get much muninicipal acceptance tracktion.  

Quote from @Gary Aragon: Quote from @Rick Albert: Our electricity is already separate and we designed our ADU to be all electric so no gas. 

For sure PG&E requires this for gas and electric, and I think most jurisdictions require it for water and sewer as well. 

Do the Airbnb discounting, price a little under market, make sure your cleaning fees are at or below average, looser cancellation policies will all help.

That might be especially attractive to folks who want to shed the clothes they wear at work to keep their living space more clean.
