Assuming this is a clean file, with no exceptions required, most Underwriters take anywhere from 48-72 hours to review a loan and get CTC, or provide further conditions. 

The guy has already stated that he doesn't live there so that alone proves that he knows that was never the intended use (is their a police report or statement for your file?).

Quote from @Cheryl Abram: What legal filed docs are LPs entitled to see to help validate a deal's failure?

Beneficial Ownership Information is back on the table. Register your corporation by 1-13-25

I'll have to try and find a CPA that will address the deadline.

I find that it's almost a one stop shop in that I can use it for my business checking and savings accounts, bookkeeping, for rent collection, I can issue virtual credit card, I can create all the financial reports I need to run my real estate business and prepare for tax filing and through their partners I can vet my tenants, develop state-specific leases and more.

As soon as a tenant fails to pay rent, you can file a complaint without waiting 30 days or issuing a separate notice (unless your lease requires one).That being said, it could be a waste of time/fees to run to court because tenants in NJ may come even on rent (even after you win the eviction case) and then they won't be evicted: “The tenant shall have three business days after service of the warrant for removal to pay all rent due.”

Curious about the reason, I consulted my home insurance broker, who informed me that the property had a water damage claim filed a few months ago, which is causing insurers to be cautious.This information surprised me, as it had not been disclosed by the seller.

Much better than a legal filing or media attention. 

The 25% has to be your funds.Now, there are non conventional options that would be a bit more flexible but even most of those programs will require at least 20% down with no second mortgages filed on the property.
