I am currently under contract for a property, and my inspection period has just expired.

I told him he can break the lease, but according to his contract until I find a tenant - he will be responsible to pay the lease.

It's a fairly unregulated space (charging grandma $750 to puts around for 3 hours, after moving the old box from the horizontal sensor, which was the only problem with the garage door to begin with), so some combination of carefully reading reviews (you have to actually read them to make sure it's not 200 fake reviews), and maybe not giving them the full contract all at once, is in order. 

Spoke with the seller a few month prior to contracting.

On another note we also have under contract a 16 unit building in Lisbon.

We can turn them around in just a days notice, we’ve actually had wholesalers come to us day of close because an issue popped up with contract verbiage or $ disclosure etc.
