As a British passport holder, you won’t need a visa. Prior to Brexit, you can stay and work in the country for up to 90 days in any 180 day period.
After Brexit, you will still be able to stay in the country for 90 days but would need to apply for work visas if you wished to work - same as on US passport; similarly, post Brexit, if you wish to reside here, the rules will be the same as if you only had a US passport. You will need to meet the criteria for a Tarjeta de Identidad Extranjero regarding health insurance and income to name but two.
If you get here before Jan 31st 2020, you will still be able to apply under the “old” regime on your British passport, then convert to the “new” without having to meet the new income requirements which are scarily high for this area of Spain.
Thats asI understand the situation as it stands today. A lot depends on the outcome of today’s General Election in the UK and if Brexit occurs, how EU citizens in U.K. are treated
