Things like having them paint the other walls not involved in the slab leak or buying me more laminate for other rooms at their wholesale price.

Catching a single one is a different story entirely.You'll need to know who owns a property, how to locate the owner, convince them to sell, know what paperwork is involved, how to use it, MONEY, and how you'll benefit once the property becomes your responsibility.Hope you sort this out and make this work for you.

Can someone share their knowledge and experience and maybe provide examples on how to draft/shape an offer where seller financing is involved.

it's really no different than a house or duplex,  just that it involves extra items.  

Last year I was very anxious as to the whole closing and escrow process and dealing with contracts (I would research into it and  people would make it seem insignificant at times when explaining their deals) But while taking this online Pre-licensure course,  I've gotten a much better idea as to the process of escrow and the things involved.

A receiver being involved means they've declared bankruptcy. 

Also I'm not sure when I should start looking for a title company and when I should get them involved in this process.

I love real estate and have been involved since I was about 10 years old, cleaning homes after they were newly built.  

So, my first flip involved my finding the property and bringing in a partner who happened to be a friend of mine and a general contractor.

I'm sure that all of your hard work will pay off in a big way in the end because it is a great site for anyone involved in RE for any reason.
