Thanks everyone for your replies. Given the neighborhood, the 6 acre lot would be divided into three 2 acre lots and each lot would have a 2,000 single family home. I think what really hit home for me (from your replies) was the fact that a 10 day due diligence period doesn't fly for land development (which makes sense).
@Karen Margrave I really like the idea of partnering with someone that knows about sub-division and land development. Unfortunately, my network only includes other investors that have done traditional flips. Do you have any contacts in the Philadelphia that have this experience and might be interested?
@Matthew Paul What would an option on the property look like? I understand the concept but how would I right that up in a contract? Would it be a clause within a purchase agreement for the existing house or is it a separate agreement?
The estate is selling these 2 properties separately, so I'm looking at the house on the 2 acre lot this afternoon. I'll also have a better idea of what the 6 acre lot looks like.
