Hey guys I am investing in Dallas Forth-Worth & Tampa area Long term rentals and I’m doing section 8 also , I am getting property with hard money loan , remodel them, and  then re fi them for 30 years , I put around 45-65K for each property I have 4 properties that cash flowing $300, $500, $1000, $250 per month I wanted to get into Multi Family - 4 plex, 6 plex and up even 8-12 units as first deal.  

You will then have a few options with that rent money....you can put it into principal or you can start saving it to purchase yet another property.

., seller financing, lease options, etc.)?

Certain suburbs don't have many options for multifamily, so you might have to open your search to other locations.

This is the 2 units + 2 ADUs scenario.I am worried Scenario A might push future financing option into commercial real estate only, which will limit my cashout refi options and the future buyer pool.From a lending perspective, since a "Land Use Restriction" is required to be recorded on the Deed to limit rentals to be longer than 30 days, the property thus will not be considered a true "5 unit commercial property" and my worries in Scenario A will not come to pass, right?

If not, do I have any other options at 20% down? 

I would probably have to return the down payment and option money to the end buyer, and he is probably going to sue me.

Also to build relationships and a team for multi family syndication projects 

We have one multi family property that is fully paid off and generates roughly $200k in NOI/Cash Flow. 

Transferring the conventional mortgage to the LLC afterward will, in many cases, trigger the due on sale clause which will cause you to go get the commercial mortgage anyways.The DSCR loan could be an option.
