What are my option here, I do not understand why $1400 was taking out of our security deposit for no reason.

I would try to secure private financing or get a partner, otherwise.

Talk to a securities attorney.

@Andy Mirza frankly I did not trust the party that put me on title so I secured an attorney to navigate the issue and act in my best interest.

Hi Tom,So in your case you are not house hacking to secure the favorable financing that you could get by living in one of the  units and therefore obtaining a purchase money loan for your primary residence since your are buying all-cash.

As @Maxwell Manatt points out- does everyone know their role and what is expected from them - because unperformed duties do not raise someone to the level of a sponsor/issuer and may create the presumption that the specific person is indeed an investor who actually purchased a security. 

I know there are different ways/methods about doing so.

My plan is to use the BRRR method and I will be looking to fund the deal with cash at about 40k (is this realistic?) 

@Tyler HoganUnfortunately, the rules do not allow for the use of solo 401k owned real estate as security for a personal loan.

My question to that response is...What ways or methods would you go about in finding and locking down private money for your deals?
