The property is only 9 years old so that's why I put only $10k also, they are opening a new company that will employ thousands of people nearby so that's why I put a 6% income growth and only 3% expense.

When legal drama pops up (and it might), a paper trail is your best friend.The TakeawayHouse hacking has been an adventure.

My company is Flex Property Management & Consulting. 

It comes down to how each county handles property tax valuation.To put it in generic terms - a title company & lender will base your initial mortgage payment on the property taxes of the previous owner.  

I currently do Business Development for our property management company and work with all of the new owners and properties.

I think there is value in ADU as long as it is legally done and can be legally rented.On the sale side a benefit can always be an in law suite.

Next question.... will you self-manage it, or turn it over to a professional management company, or some type of hybrid? 

@Bobby Paquette, someone had asked about this group a while back and I will say, there is a lot that scares me about this company.  

I have never known or had a single one done legally where any financial institute called a DOS for such, not 1 ever. 

You will want to consult with a lawyer.In regards to your last two questions here's some background on what makes a contract valid and enforceable:Offer: A promise to do or not do something within a certain time period Acceptance: A clear and direct statement that all terms and responsibilities are accepted Consideration: A legal and adequate inducement given in exchange for the promise Capacity: The parties to the contract must have the legal capacity and competency to contract Awareness: A party must be aware of the contract Legality: The contract must be legal in the jurisdiction it will be operating in***Not legal advice*** Steps I would take: -Review contract in detail to understand each counterparties responsibilities (if you are not aware)- Email a copy of the lease to each of the tenants listed on the lease and reiterate lease expectations for termination notice, rent payment etc. - If the lease was signed via Docusign (other esign may have same ability) - you can go to the envelope, go to history and view the IP addresses for each action taken.
