Purchase What I'm Currently Renting

[Dylon May]

I now have the opportunity to purchase the home that my family and I currently live in. The property manager is also willing to do a seller finance deal. I'm not sure how that works, so can you fill me in on what that means, and what that entails especially now in this economy? Would that be a good idea to do seller financing?

What would be my next step? She's already given me a sales price, however she did say that they are willing to negotiate down. Where would I go to look up comparables in my neighborhood without having access to what real estate agents have access to? We will not get a real estate agent involved, because we want to keep money in our pockets. 

I really need a step-by-step guide on where I should go from here. I am a newbie investor, and a newbie home buyer, and I do not want these people taking advantage of my family and I with our first purchase. Let me know your thoughts!
