Appraisal advice needed

[Marlon P.]

Any appraiser here???

I have a small SF house of about 512 sq ft 1b/1b)which is estimated on $160k in a 6,000 sq ft lot.

I'm putting a double wide brand new MH of around 1,078 sq ft(3b/2b) in the available land and the city request the bigger building to be the primary house and the small one the ADU.

Both Units are separated and all utilities and addresses are separated as well, they are just In the same land.

In this case; will appraisal might devalue the small unit, now named by the city ADU since the main house will be the manufactured one?

Or the small house will remain its value and now with the MH the value will increase???

Thanks in advance for your opinion.
