Elderly mum w/ fixed income: less expensive places to live besides Delray?

I’d prefer her to stay in Florida. She’s been between Delray & Boca for 30+ years. She owns her home & lives in a “regular” community (I.e. not a 55+ or retirement or assisted living community).

The rising cost of (house, car, flood, etc.) insurance & everything else is pricing her out, as her fixed income hasn’t changed.

I’d love to know other areas in Florida that have a less expensive cost of living than Delray/Boca.

Thank you!
