not sure that you are still looking for answers to this question or exactly what type of property you are looking for but many believe that Spring is a good time to list their home. TODAY is the FIRST day of SPRING !
I'd watch for a bump in the inventory. Especially now that we Realtors can take pretty photos of homes without SNOW in them !!!
Now that the 'crazy' market has ended, we seem to be back to the typical New England seasonal patterns -which means that we should see more inventory start hitting the market pretty soon. Typically in the Spring, many realize that there are more Buyers looking. What many fail to also see is that there is thypically a wave of inventory that ALSO comes at this time of year (usually a few weeks behind the first wave of buyers).
Given that Leominster, MA is one of the 1st affordble places within a reasonable commute of Boston, I see it to be an excellent value.
