@Cristal Ochoa @Leiah DotlichI will preface this with the fact that I have a legal background, specifically with estate planning and asset protection.

One common approach is to form a legal entity, such as an LLC, where both of you are equal partners.

On June 7th, we sent an itemized list of deductions via text; he responded on June 8th, disagreeing and threatening legal action.

Someone in the legal profession told me that we can give her 30 day notice and then proceed with an eviction. 

LLC offers better legal protection.3) Setting up in states that allow your identity to be hid is also overblown.

Give proper legal notice of non-renewal and get them both out.

This is for basic informational purposes I am not an attorney and this is not legal advice.First, if you offer to purchase a property using a HELOC to fund the purchase you cannot later back out of the agreement because you couldn't find PML or investors.  

I am starting the legal process as we speak and depending how many more we can make this a class action law suit. 

I think hard money lender to take this risk cannot legally charge appropriately which means the law is working against you (the law meant to protect owner occupied owners from unfair loans).I agree with @Jay Hinrichs that your best option likely is to sell on the mls.  

If you are a legal property manager in your state the owner should have the unfettered ability to allow you to act as his/her agent to enforce the lease, whatever provisions they may contain plus whatever your state laws allow.
