Looks like you've already assessed some aspects.
Other aspects include:
The price might be even lower in 2-3 years.
Borrow the money at all-time low interest for a mortgage (CM suggests either holding a house debt-free or with a large mortgage).
Put some retirement funds into PMs, if possible, for stabilty.
Don't allow too much of your net worth to be invested in real estate. I guess you're in the 45-55 age bracket so planning to have the home debt free at retirement and being about 50% of net worth at that time is a good proportion, in my opinion.

Currently renting a house, which I can buy for below current market value. House is extremely well built, but a bit larger than is required as the kids are floating in and out with college. Lot is small, but due to neighborhood arrangement, get a lot of rain run-off where the garden is located.

What are some of the opinions here?
