Hi Jerilyn,
Congratulations on your decision to flip houses! You mentioned contract assignments....do you plan on wholesaling? If so this is one of the fastest ways to generate cash flow.
As far as the Attorney goes, you want to make sure that the Attorney you choose is investor friendly. If he or she is not then find another one. This is critical if you are flipping houses.
In regard to "Assignments" it is pretty straight forward. Make sure you get a non-refundable deposit from your cash buyer in the amount of at least $2,000 with a very short (1 day) inspection period. This insures that they will close and if they don't you can hopefully get an extention.
I personally wholesale and cherry pick the best deals to fix and flip using funding from private lenders. If you don't have private money you may wany to consider finding a money partner in the beginning.
Holding properties takes time and money, so If I were just starting out in a new areaI would focus on building a cash buyers list and finding deals. Then cherry pick the best deals to rehab and after you get some deals (and cash) under your belt, hold a property as a rental, providing it has nice cash flow.
I hope this helps!
