Advice Please - New Build Homes Murcia Coast

Looking for advice please. We are considering moving to Spain as I've recently retired. We've narrowed our search to the Murcia coastal region.
We are considering buying a new build property.
I would appreciate some advice please on the following:

Do New build properties in the area retain their values?

As we are looking to split our time between Spain & the UK do Villas rent out easily in the coastal areas?

Which area of the Murcia Coast would you recommend?

Many Thanks

We have not yet moved there (next year), but I would suggest doing some research on problems (and, occasionally, benefits) with new builds. Also, if you haven't ever watched Spain Speaks (in English by an Australian), do a search on Youtube. He has a couple of segments on buying a flat in Spain, and special  advice on new builds.)

What do you like sea , or tourist places,  or green landscapes,  so I can help you , I hope for you all the beas
