I think most regionals reserve rules will give you about 12 days off per month, usually 2-3 days off at a time. I work for Eagle, and they allow reserve pilots to swap days, so you can sometimes wind up with a string of 6-7 days off if you get lucky. The further away from base you live, the worse your QOL will be (especially on reserve).

Once you get off reserve and can hold a regular line it would probably be working 4 day trips, with 3 days off in between. We have an FO who commutes from Ireland, and he swaps his trips around so he works a 4 day, with 1-2 days off then another 4 day usually winding up with 6-8 days off at the beginning or end of the month. Depending on your finance situation, you can drop trips (unpaid) to get more time off if you prefer.

It might be difficult, but if you have to do it... good luck!
