There is a solid comp two doors down that sold for 160k, we are trying our best to bring our property up to par with that renovation. 

So if the home sold for $100,000 and you owed $30,000, you would keep $70,000 when you sell it. 

I put the ARV around, what I believe, a very  conservative $140k for the area based off what I saw some homes recently sold for.

If he hadn't sold, he'd still be out of pocket $20k.

If you hold firm and lose and find out the deal sold for $1000 more than you offered... you really lost out, IMO.

If you use it and it saves you time and gives you a tool for the rest of your life -it's priceless. 

The last time the house sold was back in 2010 for ~144k. 3 family house in question has its issues(older home, older heating systems probably)  but I would like to own it as it would: 1. eliminate my driveway/snowplowing issues 2. add to rental portfolio 3 increase monthly income 4.

I witnessed this on a flip I sold in Philly and this post motivated me to look back at the details. 

It hasnt sold for six months. 

@Rob Drum Yes, Google Maps has been a wonderful tool!
