I like to stay local and self manage, so all my properties are within 20 minutes drive from my house, most are actually within walking distance. 3-4 bedrooms seem to be more in demand than 1-2 bedrooms.

Wanted to take advantage of high demand Class A rental market & avoid competitive Spec Build market.

So the demand is there.

We have high demand in ours but some prospective tenants are looking now, but want to move in a couple of weeks.  

BRR is going to be a-little hard until you get volume due to the recent increase in demand for single family home rentals.

The smaller counties have better margins, but less demand so the risk and vacancy is going to be higher.

So there may be a bit of a demand.

An increase in population creates a demand and helps the economy to grow.

But you ought to demand a discount.And I'd be very careful because there is also some very specific restrictions about the numbers of properties you can identify and valuation limits since you're naming more than 3 properties. 

That being said, the demand for ADUs in California is very high.
