I can't understand what どくしんで means (I know there is the のです here but I can't
understand the verb before it).

Also, in the second part ハンサムだから, I studied that から is Place at the end of the
first sentence with the second part of the sentence following it (...だから...),
isn't it?

Thank you

What does どくしんでハンサムだからね mean?
> 独身{どくしん} で ハンサム だから ね

Without further context it's hard to tell who is the subject/object of this
phrase, but it shall be read:

> It's because だから  
>  _someone_  
>  is single and... どくしんで  
>  handsome ハンサム

> [one or more factors that make one popular etc.]だからね

This is a common phrase to acknowledge someone for being pretty good in some
way (popular, smart, etc.) either in front of them or when gossiping about
them.

It's basically "It makes sense how he's popular with women when you know that
he's single and handsome."

Japanese people fill in that sentence like this in their minds:

> 独身でハンサムだからそりゃモテるよね

  * そりゃ slang for "of course," "naturally," "then" 
  * モテる "to be popular with the opposite sex"

In the sentence you wrote, it sounds like the speaker is talking to their
friends about how some guy they know is popular.
