Can/do you make low ball offers?

[Fabian Friedrich]

As noticed in other threads it seems hard to find good cash flowing deals in NoVa.

Often times I would have to buy 10-15% below the listing price to make numbers work.

Is it worth making an actual offer at that price (e.g. 220k vs. 250k listed) or would this be offending/lead to negative reputation?

Is it a good idea to spend time. Keeping properties first or just shooting off a low offer based on data available?
