Right now it's just an idea for me but it seems like it's just a little bit of extra language in a regular lease, maybe it's more complicated than it seems? 

If you take a duplex that will be worth $150k once it is renovated, if you bought it for $100k and put $20,000 into it to fix it up, your cash out at refinancing time would (typically)  be 75% ($112,500)... so you would get back out of it all your initial money, less $8,000 of what you spent renovating it... but this plan requires $120,000 in cash to pull off... so you can see that BRRRRs can be complicated on limited funds.  

What are some ideas on navigating this zoning complication.

There's no tax due in this process, but there're legal, lending, and insurance complications that need to be taken care of.- Partnership is risky.

If the chip happened somewhere else, perhaps in an edge treatment more complicated than a simple eased edge, that just reveals more of the unpredictability of granite in rentals.

If you elect S Corp tax status that just costs more, more complicated, and even less efficient if not “negative efficiency.”I don’t see how how this will work.

As your business grows you may find reasons to add more accounts but wait until the need is there don't complicate your life unnecessarily. 

You are way over complicating this, @Eric Quezada.

Plus, many other aspects make its much more complicated. 

What are some ideas on navigating this zoning complication or would this be a safe purchase as is?
