If your newer home has a more modern layout or amenities, then that would increase value.

There is a drawing of the layout in the ad, and it appears that the one unit is enormous, and could easily be converted into a 4 plex quite easily.

In this situation, we have taken several actions that have vastly improved our tenant quality, including:1) Making sure we have at least 10 great pictures of our unit in the advertisement2) Our advertisements clearly lay out our requirements: One full year at current or previous job, weekly gross income > $xxx , Paying and approving email for a Transunion smartmove criminal, credit, and eviction checks, having no more than one eviction ever which must be disclosed, explained,and paid off.

What is the layout (#beds/#bath)?

I would focus more on a good layout that makes the ADU feel roomy.

Purchase price: $225,000 Cash invested: $101,000 Sale price: $402,000 Purchased a foreclosure, opened up and updated kitchen, changed layout of master bathroom, fixed up bathrooms, refinished floors and sold property in 3 months.

As long as it has a good layout, I am ok with some construction. 

Unless an agent has a layout listed then don't trust it.

At that consultation, you can lay out your scenario and ask specific questions about the law and how the attorney has handled such matters in the past.

Nearly every State's contract has a section for special instructions to lay out terms, add extra documentation etc.
