I refinanced my primary residence 2 months ago to take advantage of the great rates right now.

what the above posters have said.The main advantage of having a single agent is the ease of communication in the transaction.

It can be a condo, SFH or a MFH.Make sure you follow all the rules with setting up a qualified opportunity zone if you want to take advantage of benefits.The IRS has designated many ways to determine the land value for a property.

Soooooooo many advantages over a house.  

You can lose it all under each scenario if the value of the asset falls by more than the equity that you have put in.4) The syndication has several advantages which I will cover below but these benefits carry the additional risk of having a third party in control, I.e. the sponsor.

And because this US LLC company does not have any nexus, it's an advantageous setup to use for us.So yeah, can I do the same for the real estate LLC? 

And it's actually to your advantage. 

Can I take advantage of current low rates, take out some equity, and lock a 30 year term?

Opportunity Zones are new, and have big tax advantages to for developments deals held over longer periods of time.   

Depends on what your strategy is... if you are house hacking then you will not be using an LLC since you will take advantage of a FHA loan with a small down payment... if you are doing a buy and hold then having it all in an LLC is beneficial to mitigate some liability.
