I find the interface easier to manually update rates across my portfolio, OwnerRez doesn't easily let me match rates across my properties on a spot basis (unless anyone here has other recommendations that uses OR).  

I have not, but as a licensed broker I would recommend listing on MLS which will post it to Zillow, Realtor.com etc. 

I fairly positive that wont work, i have read that contacting mortgage brokers is the best way to go if you can find one.

If you are looking for proper guidance from someone that has house hacked quite a few times and has the knowledge and experience to help get you going in the right direction, I recommend reaching out to @Josh Green.

Hi BiggerPockets Community,I’m excited to join this amazing platform after reading about it in House Hacking Strategies.

Quote from @Marc Shin: Would like recommendations for curtain colors and rug colors for this living room.

Which is why I always send the listing to the sellers to proof read everything.

What would you recommend?

I would recommend leveraging the BP forums to connect with existing syndicators.

I have also read alot of books.
