Price aside, what is the down payment and the loan specifics. If you are interest only, or anything other than 20% down with a fixed traditional, you won’t survive the very real possibility that this is not the bottom, even if it goes flat you lose. It is totally normal for a young couple to be house poor for a few years. The stress of resetting payments is far greater than the stress you get from a young woman with a child and her instinct to “nest.”
If you truly can afford it, 4-s is very nice for a young family and will always be. I think that because so many of the homes were purchased during the peak, it has room to fall and waiting until after the summer has passed will be worth it.
