Is the configuration existing ?

If you are not representing the property as having an ADU and you really do have the property configured as a single family home then the second meter should not be a determining factor regarding classification.Do not keep it as a duplex and then when it is appraised try to play make believe with the appraiser that it is a single family home.

(it can not be divided into multifamily due to house configuration).Would it be more wear and tear with the big house or is it better to buy on the smaller side?

Many realtors I know have 20 or more doors in that configuration as they are cash cows.

The interior configuration of the buildings allow for flexible reconfiguration to accommodate a variety of tenant uses.

KVCore has a chat feature for support that can help you with the configuration once you determine the rules for your state.

Here, you can create 'mock' documents that in configurations can be set up to not manually upload into your brokerage's interface/software.

Speaking configuratively.

Once we understood these, we translated them into four property characteristics: type, configuration, location, and rent range.

I would put up a lot more in-focus photos, of each room and the bed configurations and sizes, all of the bathrooms, more of the kitchen showing the fridge and the dining area, and the backyard or porch with the barbeque you provide.
