Have no more than three bedrooms.

**I'm wondering specifically about:- Cost to furnish - do you work with an assumption based on the number of bedrooms? 

If you have a 6 bedroom in an area that does not have a university (students looking for shared space) or is in a family friendly place it may sit vacant longer between tenants.For Capex, try not to use a generic number - look at the roof, furnace, hot water tank, kitchen - when will each need to be done and what will it cost?

You are absolutely right, this residential care model is needed EVERYwhere and the demand will only double over the next decade, but supply will continue to fall behind.

But better safe than sorry, becuase people will pass on your place and you will never know the reason.....Like @Michael Baum said, there are many option like the mini stackables nowadays....

You might also want to double-check if having a local property manager satisfies the city’s requirements or if the operator still needs to meet the residency rule.Good luck with your Airbnb arbitrage—Cincinnati can be a great market! 

Or double triple lot property.6.  

Averaging $1k/mo per bedroom which is now on the cheaper side of things. 

Otherwise everyone paying double or triple would be an idiot.

No, I only really remodeled the master bedroom after I bought the house.
