Hi Phil,
This would be fine as-is, but I have some suggestions (which you shoud feel free to ignore
)
It's sometimes helpful to start of right away with what you want.
I'm writing to request an exception to the policy on the number of homes in Foxford that can be rented. I have been a resident here since 2001.
I think that "recently married" and "six months ago" are redundant, but not to an appalling level.
I would put the part about your parents right after "My wife and I do not want to sell our home because my parents are retiring in two to three years and have ...our home. Therefore, we would like to hold the property for them so they can live closer to us, and rent it out in the meantime. (You can then delete the part about "do not want to sell our home.")
Congratulations on your marriage, and good luck with the house.
