The "purely code" stables, I wouldn't suggest.

Although many properties with a specific zoning code are technically eligible, they would be subject to an extensive waitlist that could last years.

I had an electrician run wires in an attic, telling me up front that the house won't be up to codes, he's only doing the one or two things I asked.

So, create status codes for both of these and a few in-between codes to help you work smarter, not harder.

Just off the top of my head, I wouldn't feel super comfortable with non-US properties because properties in the US are held to HUD code (at a minimum).

But we can only assume since you stated this does not have to be disclosed because the work has been repaired, that you have confirmed the reapirs were done properly and in acccordance with any and all codes. 

Is there a way to find local developers based on zip codes on this forum?

Usually I use smartlocks, but for this type of volume, I'm thinking more typical locks that have a set of codes. 

It's an endless game.Recently, one of the tenants being evicted reported a broken heater to code enforcement and the Department of Children and Families (DCF).

Maybe also include City and Zip Code as columns in the sheet.
