You can absolutely juice your rent potentials by offering more living space, but new bathrooms are an undeniable value-adder. 

Thanks again, #toosoon for this girl, I am glad I could put a laugh in your belly, unintentional as it was. :)

Get the creative juice flowing when you meet with the contractor.( You may have done this already ) - Speak with the Coconino County Planning and Zoning Department: The county planning department can provide guidance on the specific requirements for obtaining a conditional use permit.

Here's a very basic explanation to get your juices flowing:Assume a house costs $200,000 and rents for $1,500.

Props for thinking outside the box but I do not think the juice is worth the squeeze. 

Juice isn't worth the squeeze unless you are in it for a LONG hold. $250k+ 

@Steve BellI guess BP has some more marketing to do!!! 

When you’ve sucked all the juice you can from your bread and butter, start scaling up.

@Idris HaroonLets put it this way, if everything went belly up you wouldn’t be able to afford the property taxes on a large portfolio.

Again, that is assuming the U.S. doesn't just go belly up.
