My brother is a master carpenter but since he retired has not so much as lifted a hammer and has no intention of doing so . It was never something he really loved doing .
It’s OK as long as it works out even stevens but resentment can build up if one sides got nothing to give back and just use friends and family as a free service
My old man’s in the building trade and he’d help anyone out but some people get cheeky
And my son’s a techie and people do expect him to fix their computer problems
As a rough guide, if it’s something you’d usually pay for and there’s no favour you can do for them back in the near future, then I think you should pay them, tax not withstanding!
I have recently drawn up some plans for a pair of semi’s for my builder and they were passed 1st submission. He did some work on a couple of properties for me without money changing hands, if that is what you mean.
I used to belong to a skill share group. We offered our skills / effort for credits, not cash. So, for example, I might offer some gardening or hypnosis to say Sue & get a massage or some sewing done in return by Kate, or Terry.
It was a community & we could only draw once we had put in. But it worked for me & many others.
