Hi 2TP. I would say no on the lawn maintenance because you do the chores where you live (so what if they don't include a lawn, or maybe they do, but it's for the sake of argument). You would love to be living in your house and would do those chores if you can live at home, but since she wants you to live elsewhere your chore duty is all used up at your place.
It is tempting to think that the money you're saving is your own money by doing it yourself. That makes sense if you're in a temporary stage. But if she's going to live there indefinitely and you're not, she needs to be independent and learn how to do the maintenance or pay someone to do it.
That is how I would approach it if it were me. Alternatively, I would charge her 80% or so of what market rate for the services is. Have her get a quote or two and pay you to do the job.
But I'd rather see you back in the house and taking care of it, personally.
