How do you decide which houses to buy and rehab?

We search for homes in distress in one of the neighborhoods where we work. We look for houses that will have an impact on a given street or block when we have completed our work. We aim to “cluster” the houses close to other homes under rehabilitation. That might mean investing near a home that a landlord is rehabilitating. It might mean working with other nonprofit or for-profit housing developers. It may also mean that we simply purchase multiple homes in a given area. Frankly, we also seek out houses that we can afford.
