How to find DADU ARV
I am currently building at Detached Accessory Dwelling unit (DADU) behind a property I am about to rent. I am building it to improve the cashflow of the property overall. Although there are new single family builds nearby, there hasn't been a house with a DADU that sold in the last 12 months, making it difficult to come up with an ARV for it (DADU). Outside of hiring an independent appraiser, any advice on how to find the ARV for the DADU? Just want to do some quick preliminary math.
