It is very small photo. Could you post better one, closer?

In addition to larger maybe one a different angle to eliminate the trees so we see the house..............................

definitely need a better photo but for coastal homes i like blues, whites, and yellows! https://www.buildersservicecompany.com/how-to-choose-a-siding-color 

More pictures of the house.

Here is visual with classic white +black door

or warm greige+navy door

Body: SW Agreeable Gray

or BM Edgecomb Gray

Trim: Bright white (SW Pure White or BM Chantilly Lace)

Front Door: Navy blue

Dress Blues SW

Marine Blue BM

Naval SW

Does it need paint? If you paint, will you get your investment back? I'd talk to realtors about that. Painting is expensive and I like the current blue a lot more than greige, which is a dreary color if there ever was one.
