We reached out to the seller but he stated he did not receive any deposits.

I guess this adds even more confusion in that the second home requirements state renting it is fine as long as it follows the guidelines, not that it’s forbidden outright.  

You probably shouldn’t use state-wide numbers.

What state is the property you're looking to buy in?

As such, there are strict requirements that Hawaii State Law Quiet Hours must be observed outside the home past 9:30 PM (feel free to go snuggle up with some popcorn in the 16-seater movie room!).

In most states, there is a 2 years timeframe for someone to dispute a claim for a refund or any other related money issue. 

File your state tax return with Maryland, then the amount your return says your getting back will be sent to you in the manner you indicated on the return.

Also, when done properly, the buyer takes out an insurance policy that states if the due on sale clause is called, then the insurance company will pay the mortgage company and originate and hold a loan on the existing terms. 

If we buy house now for house-hacking, and move in the next year or two, we still need to manage it out-of-state, right?

The best success I have had with seller financing is to listen first to the sellers problem before proposing a solution.Typically a seller finance transaction involves :1) Purchase & sale agreement2) Note3) Recorded deed of trust or mortgage depending on your state.
