Is there a particular saint

Is there a particular saint to pray to for discernment?
Yesterday we went to look at a house that someone mentioned was free out of the blue. Moving to the country was something we have always wanted to do for years now, but figured “we would someday”. It is not a desire I have had until we moved to upstate NY. I am not sure if it is an age thing, a child rearing thing, or the fact that once you see how incredibly beautiful New York state is, you feel sad returning back to the city because you feel short changed.
We saw this house yesterday and it is a dream come true. Thirty acres to open the back door and say “boys”( remember I have three so far) “go outside and play”. I cannot do that here in Albany. No neighbors complaining about how noisy we are, no teenage boys next door making nasty remarks about how he should “come over and visit me” because I had so many babies. This house would save us literally $375 a month in housing costs alone, and probably another $200 in heating costs a month. I could put my children in all the activities I wanted to with the extra denaro. My husband could go back to school 6 miles away instead of 40. Although he would be trading a 20 minute commute to work for a 50 minute one.
So what is the problem? Number one, I am afraid to make such a huge decision on the curtails of our marital problems. However, all the problems my husband was stressed about, or so he said, this literally takes care of them. Maybe that will help (so he can get some). Number two, I have been dying to move to the country, now that I may, this city girl is intimidated by the idea of having no neighbors.
It seems like a chance from God, but I just need to pray for discernment to know for sure.
