@Jenna Stark your absolutely right and thank you! Just sharing proof of concept. Your question about ADU appraisals is a great one. That's a code I've been trying to crack and my approach is this…
1. always buy in a area where you can find ADU comps. Even if the comp is in a city near by, appraisers will use it. As long as the city is similar. A couple local examples… Norwalk and bellflower have great comps on ADUs, but most ppl are keeping their homes/ADUs VS selling due to the great CF.
2. Deal with a banker that has a great relationship with their appraisers. I would even ask if that appraiser is familiar with ADUs.
3. Do your our research/gather your own comps. I track every ADU sold in the last 2 years in the areas I invest (it's not many), but it helps. I sent my appraiser an email of all the ADU comps he can use and I handed him a print out of all my comps when we met. This helped a lot.
Hope this helps. If your local we should meet up if your considering investing in ADUs.
