If this is a single family house and you intend on leasing the home as a single family house and there are no active violations on the property, I don't foresee any issues with this being a 2 bedroom home as opposed to its previous layout.

Here's my #1 dissatisfier in dealing with agents: Most have NO idea how to evaluate investment properties.I HATE when agents bring me a so-called "deal" without having first determined whether it actually makes sense financially.Then, when I do run the numbers and calculate a cash flow of $50/mo and a cash-on-cash return of 3%, I feel violated, like my time has been totally wasted.And, that's the last "deal" I'll ever consider from that agent!

There has been numerous violations to the lease.

Any truth to this or is there some policy I might be violating with these questions?

Engaging in a variable rate commission and not disclosing it (essentially making the playing field even so everyone knows the rules) is a violation of the NAR code of ethics, and in many states, a violation of the law. 

I am considering evict my tenant with at fault just cause due to the lease violation ( parking, trash, common area cleanliness).

Even gave me a big discount.Alright, we strongly oppose it as it infringes upon property rights and violates the Fourth Amendment.

Or tenant gets mad  and complains to the Rent Board "hey my landlord has an illegal ADU, fire code violations, mold etc."

For example, if the person selling the property was related to you - that would be classified as a non-arms length transaction...and that would violate the terms of a delayed financing transaction (keep in mind this article demonstrates how to NOT be a delayed financing transaction).

Quote from @Gagan Saini: Can you DM me or post your proof of copyright ownership and/or trademark rights that I am accused of violating?
