Deciding when to make an offer

[Nathan Churchill]

Hello, BP! I've started my journey into real-estate and my wife and I are in search of our first deal. We've looked at a couple of properties, but both ended up being a bit more work than we wanted for the price that was being asked.

I'm wondering, when you find a property you like do you usually make an offer based on what numbers work for you? For example, if there's a house listed for $90k, but the numbers don't work until a $70k purchase price do you go ahead and offer $70k and just see what happens? Is there any downside to making low-ball offers?

What's your trigger to make an offer on a property, low-ball or not?
