A wise investor will not try to get rich quick with shortcuts.

There are many shortcuts to deciding if a purchase is a good investment. 

Feel free to PM if this interests you and you want to know more.As far a the deal, you could 1031 into your own deal(s) and learn fast (get help on this if you are serious about shortcutting your path to success). 

If the insurance company paid you more than the roofer is going to charge, there's a very good chance your roofer is not a quality roofer and plans to take some shortcuts or use lower-quality materials to keep the bid low.If it's a true over-payment, I would talk to the insurance adjuster and figure out how to return any unused funds.

There are other restrictions that go with the zoning, which will require some sifting through Title 21A of the county code, or you could shortcut that search by talking with the local planning department as noted above.As Nik notes above, individual cities may have their own zoning codes. 

It sounds like you're just rushing toward revenue and possibly taking too many shortcuts along the way.

But it does take time, and if there's a shortcut to all of this, I'm not aware of it.

Unlike the real cost seg studies, those shortcuts do not have to be accepted by the IRS.

I’m just trying to figure out if our contractor took a shortcut and it has to be redone or maybe the paint hasn’t yet had enough time to fully cure.

That seems like the shortcut to taxes and interest owed, maybe not penalties owed if no fraud was intended.
