There’s just not enough ADU supply (IN MY AREA) for appraisers to base off of.

The process went smoothly, and I’m happy I got a tenant so fast, but the high supply of new builds in the area makes me nervous.

Depending on the number of jobs and number of new development going on in the area it may just be simple supply and demand.

Hi Jemini, I would start by doing research in the markets you're interested in to see what the rents vs. purchase prices are along with looking at the supply and demand of the market. 

Additionally, the supply of homes for sale is constrained because of this and will be for some time putting upward pressure on prices in most markets.Thinking about renting your house in Seattle would be wise as someone else will pay the mortgage down, and rents and the value of the property will go up over time.
