I currently own three separate multi family properties and I’m looking to syndicate my next purchase with investors but would like to understand the best effective syndication model that has worked for others with investing in 20 to 40 unit properties.

Another consideration is that most state laws specify "Security Deposit" so naming it something different could have side effects on common law understanding. 

I know there are still many real estate owners out there that are struggling from the effects of the COVID-19 Pandemic.

You could always turn direct book back on if it looked like you were effected.

Recently I applied for pre-approval in order to start looking for small multi-family units to do an owner occupied house hack, I was, unfortunately, denied pre-approval due to my low income.So I had an idea and I was wondering if this is 1) Legal/Feasible 2) Effective/Smart or Not.

I was wondering if anyone had advice on how to analyze a property after driving for dollars in my areaThanks in advance for your time!

Note again that you pay the LP investor down with return of principal along the way which makes the effective preferred return base smaller - so you get more of the 20-30% split.  

With this being an income-generating property that is cash-flow positive, this should not have negative long-term effects on you or the co-signer's DTI. 

Super easy and cost effective way to re-key the locks. 

There are some legal issues with this and it is not a good term strategy to grow (it will negatively effect your individual and company reputation).
