In order for me to properly analyse these, I would need  financials on said properties.

I noticed the agent struggled getting the house properly setup on Zillow and didn’t understand what Instagram was.

Make sure you are properly prepared. it will take even longer to get started if you get burned. 

For the most part if your contingencies are in place for an offer, and you've got the proper timing in place (response to offer, response to inspection, etc.), you should be good.

Because the place was clean nice, livable and functional before. 

When people do properly insure the property, the lender is notified and the due on sale clause is triggerer.So essentially everyone that does this, but who do not get caught, usually do not have a valid insurance policy on the property.

I noticed that many towns/cities doesn't allow STRs and existing ones might be functioning illegally.

That said, yes you should be completely fine if you plan it out properly and order materials as soon as possible (big delays happing) and make sure your inspections are scheduled out to meet up with the work so you’re not killing days.

Other non-payment evictions have been going on since the courts reopened early last summer.We have been focused on collecting by making sure everyone jumped through the proper hoops to get aid money.

Please check with your laws in your state to make sure of proper notice.
