Purchasing a property in Pittsburgh through seller finance

[Joshua Smith]

Good evening,

My wife and I have the opportunity to purchase our first investment property, her mom's house.  We are newbies in the game and we want to do seller financing to take over the mortgage.  We live in the Pittsburgh area, and her house is in an up and coming neighborhood.  Her mother is having mobility issues and we feel like this could be a great chance for us to take, while improving her quality of life.  With some TLC, this is a diamond in the rough!  I have been researching this topic and have consulted another investor friend of mine.  However, any further insight on the topic or directions I need to look at, or steps to take, would all be great.  Thank you.
