These are regulatory burdens, not Patch of Land's.

Is there any legal or regulatory restriction on me closing all 10 deals?

Like insurance, regulatory fees, memberships, registration, etc.Thanks!

Many businesses can be verified through their state's regulatory agency.

But I now realize that the text in your post fully describes the way I feel about some people running the regulatory institutions, including the top dogs in Washington.

Technically EVERYONE is supposed to get your explicit consent to run your credit if you do not already have an account with them (a "soft pull" is when an existing creditor is a "subscriber" to your credit, gets a fresh copy on a monthly basis, and double clicks to open it... you don't know this is done just like you don't know who opens your yellow letters, if you send them), but mortgage lenders face greater regulatory scrutiny, so we tend to actually follow the rules. - No one has a perfect credit score.- If you do not have a perfect credit score, but have unblemished credit, the credit reporting agencies still MUST give 3 reasons why you do not have a perfect credit score. 815 v 795 is normal month to month variance.

This does give some regulatory uncertainty to those investors looking to buy a property for an Airbnb/STR.

Will owning a financial commitment like an SFR loan place my company into a different status with regard to new fiducial/regulatory/reporting obligations? 

The markets where you tend to make the most money, have a lot of regulatory crap to deal with. 

With a normal mortgage, and Post Oct 2015's regulatory changes slowing things down (TRID), 11 days to keys in hand is my personal record.
