Boston (Weston MA) Flip Question!

[Art Campbell]

So my partner and I are in talks with an owner in Weston MA about a 3b/2ba. Is got good bones but hes asking 575k for a 1 acre property. We think the ARV is somewhere around 850k and the total rehab (fresh interior / some exterior / some hardscape, holding costs, investor waterfall, etc) will sit somewhere around 210k and 6 months time. The property is on a fairly busy road though and we arent sure about the deal.

Anyone familiar with the area?
