First - I am a Realtor that lives and works in Springfield, Mass.
Second - with regards to the market for single family homes in East Springfield. Buyers are generally "lazy" with regards to the fact that they would prefer to buy a house in move in condition that will remind them of the homes on HGTV. If you leave things like the kitchen, carpets, paint colors, etc for them to pick - they will just move on to the next house. So if you rehab, keep that in mind that you should rehab as close to 100% as possible of the visual items.
Specifically on the stats - in the past six months in East Springfield...
23 houses sold between $100,000 and $149,999 (87 days on market)
8 houses sold between $150,000 and $199,999 (141 days on market)
3 houses sold between $200,000 and $249,999 (50 days on market)
1 house sold between $250,000 and $299,999 (5 days on market)
Just so you know - there are currently 24 houses on the market in East Springfield between $150,000 and $199,999 ~ or roughly 18 months worth of inventory based on the past six months worth of sales. So if this is the range you are looking at than you better make sure you have location and condition in your favor so you are one of the ones that sells in the next six months. Also, do not get greedy. Price the house to sell, not to make a killing.
