P.S. when there has been a fire generally the city is involved, that means everything needs to bring brought up to current codes. I don't think your first deal should be this. It is very hard to do because it is like building 2 new houses. Sometimes it is even harder!!!
My first deal was a burn out, I bought it for 14,000. But here is the catch, I paid $1 and then the $13,999 when I sold it, It cost me about $30,000 and sold it and make $27,000. I was a punk 23 year old kid in the late 70's.
I had to deal with city inspectors and do everything to what they said. What a hassle!!!
Permit for everything!!! sometimes they would re schedule and then the property/project got delayed.
Unless you buying this for pennies on the dollar, I would re consider your first deal doing this!
The owner most likely got 70% of total value in a check. But the owner still has to deal with 2 units basically un safe etc for months, and demo of same is a lot of cash to remove.
